The '''Australian Defence Force''' ('''ADF''') is the [[Armed forces|military organisation]] responsible for the defence of [[Australia]] and its [[national interests]]. It consists of three [[Military branch|services]]: the [[Royal Australian Navy]] (RAN), the [[Australian Army]] and the [[Royal Australian Air Force]] (RAAF). The ADF has a strength of just over 90,000 personnel and is supported by the [[Department of Defence (Australia)|Department of Defence]] alongside other civilian entities also members of the [[Australian Defence Organisation]].

During the first decades of the 20th century, the [[Australian Government]] established the armed services as separate organisations, with each service having an independent [[chain of command]]. In 1976, the government made a strategic change and established the ADF to place the services under a single headquarters. Over time, the degree of integration has increased, and tri-service headquarters, logistics, and training institutions have supplanted many single-service establishments. The ADF has been deployed around the world in combat, [[peacekeeping]] and disaster-relief missions.

The ADF is technologically sophisticated but relatively small for its landmass. The ADF has 58,909 full-time active-duty personnel and 33,269 active [[military reserve force|reservists]]. The ADF has the largest military in Oceania, although it is smaller than most Asian military forces. The ADF is supported by a significant budget by worldwide standards and is well equipped and trained, with defence spending at 2.02% of GDP.

===Formation===

By 1870, each of the then Australian colonies [[Colonial forces of Australia|maintained their own military forces]]. On 1 January 1901, the colonies [[Federation of Australia|federated into a new nation]] and on 1 March 1901, these colonial forces were amalgamated to establish the [[Australian Army]] and Commonwealth Naval Forces.<ref>{{Cite web |title=The Australian Army |url=https://www.awm.gov.au/learn/understanding-military-structure/army |access-date=2024-02-16 |website=Australian War Memorial}}</ref><ref>{{Cite web |last=Greg |first=Swinden |date=2011-06-14 |title=Australasian Naval Forces and Commonwealth Naval Forces |url=https://navyhistory.au/australasian-naval-forces-and-commonwealth-naval-forces/ |access-date=2024-02-16 |website=Naval Historical Society of Australia |language=en-AU}}</ref>{{sfn|Grey|2008|p=67}} In 1911, the government established the [[Royal Australian Navy]], which absorbed the Commonwealth Naval Force.{{sfn|Dennis et al|2008|p=467}} The Army established the [[Australian Flying Corps]] in 1912 which was separated to form the [[Royal Australian Air Force]] in 1921.{{sfn|Dennis et al|2008|pp=61, 457}} The services were not linked by a single chain of command, as they each reported to their own separate Minister and had separate administrative arrangements. The three services saw action around the world during [[Military history of Australia during World War I|World War I]] and [[Military history of Australia during World War II|World War II]], and took part in conflicts in Asia during the [[Cold War]].{{sfn|Horner|2007|pp=145–150}}

The importance of [[joint warfare]] was made clear to the Australian military during World War II when Australian naval, ground and air units frequently served as part of single commands. Following the war, several senior officers lobbied for the appointment of a [[commander in chief|commander-in-chief]] of the three services. The government rejected this proposal and the three services remained fully independent.{{sfn|Horner|2001|p=42}} The absence of a central authority resulted in poor coordination between the services, with each service organising and operating under different [[military doctrine]].{{sfn|Horner|2001|p=44}}

The need for an integrated command structure received more emphasis due to inefficient arrangements [[Military history of Australia during the Vietnam War|during the Vietnam War]] which at times hindered the military's efforts.{{sfn|Horner|2001|p=44}} In 1973, the Secretary of the [[Department of Defence (Australia)|Department of Defence]], [[Arthur Tange]], submitted a report to the Government that recommended the unification of the separate departments supporting each service under a single ''Department of Defence,'' and the creation of the position of Chief of the Defence Force Staff. The government accepted these recommendations, and the Australian Defence Force was established on 9 February 1976.{{sfn|Horner|2001|p=47}}

===Defence of Australia era===
[[Image:Kangaroo 89.jpg|thumb|left|alt=A group of men wearing green military uniforms walking across barren ground.|Australian soldiers lead a column of American troops during Exercise Kangaroo '89, which was held in northern Australia.{{sfn|Horner|2001|p=65}}]]
Until the 1970s, Australia's military strategy centred on the concept of "forward defence", in which the role of the Australian military was to co-operate with allied forces to counter threats in Australia's region. In 1969, when the United States began the [[Guam Doctrine]] and the British withdrew [[east of Suez]], Australia developed a defence policy which emphasised self-reliance and the defence of continental Australia. This was known as the [[Defence of Australia Policy]]. Under this policy, the focus of Australian defence planning was to protect Australia's northern maritime approaches (the Air-Sea Gap) against enemy attack.{{sfn|Tewes|Rayner|Kavanaugh|2004}} In line with this goal, the ADF was restructured to increase its ability to strike at enemy forces from Australian bases and to counter raids on continental Australia. The ADF achieved this by increasing the capabilities of the RAN and RAAF and relocating regular Army units to northern Australia.{{sfn|Horner|2001|p=72}}

At this time, the ADF had no military units on operational deployment outside Australia. In 1987, the ADF made its first operational deployment as part of [[Operation Morris Dance]], in which several warships and a rifle [[Company (military)|company]] deployed to the waters off [[Fiji]] in response to the [[1987 Fijian coups d'état]]. While broadly successful, this deployment highlighted the need for the ADF to improve its capability to rapidly respond to unforeseen events.{{sfn|Horner|2001|pp=225–227}}

Since the late 1980s, the Government has increasingly called upon the ADF to contribute forces to peacekeeping missions around the world. While most of these deployments involved only small numbers of specialists, several led to the deployment of hundreds of personnel. Large peacekeeping deployments were made to [[Australian contribution to UNTAG|Namibia]] in early 1989, [[Australian contribution to UNTAC in Cambodia 1992–1993|Cambodia]] between 1992 and 1993, [[Operation Solace|Somalia]] in 1993, [[United Nations Assistance Mission for Rwanda|Rwanda]] between 1994 and 1995 and [[Bougainville Province|Bougainville]] in 1994 and from 1997 onwards.{{sfn|Horner|2001|pp=228–255}}

The [[Australian contribution to the 1991 Gulf War]] was the first time Australian personnel were deployed to an active war zone since the establishment of the ADF. Although the warships and [[Clearance Diving Team (RAN)|clearance diving team]] deployed to the [[Persian Gulf]] did not see combat, the deployment tested the ADF's capabilities and command structure. Following the war the Navy regularly deployed a [[List of recent Australian warship deployments to the Middle East|frigate to the Persian Gulf or Red Sea]] to enforce the [[Iraq sanctions|trade sanctions imposed on Iraq]].{{sfn|Horner|2001|pp=231–237}}

===East Timor deployment===

In 1996, [[John Howard]] led the [[Liberal Party of Australia|Liberal Party's]] election campaign and became prime minister. Subsequently, there were significant reforms to the ADF's force structure and role. The new government's defence strategy placed less emphasis on defending Australia from direct attack and greater emphasis on working in co-operation with regional states and [[Foreign relations of Australia|Australia's allies]] to manage potential security threats.{{sfn|Horner|2001|pp=95–96}} From 1997 the Government also implemented a series of changes to the ADF's force structure to increase the proportion of combat units to support units and improve the ADF's combat effectiveness.{{sfn|Horner|2001|pp=93–95}}

The ADF's experiences during the [[International Force for East Timor|deployment to East Timor in 1999]] led to significant changes in Australia's defence policies and, an enhancement of the ADF's ability to conduct operations outside Australia. This successful deployment was the first time a large ADF force had operated outside of Australia since the Vietnam War and revealed shortcomings in its ability to mount and sustain such operations.<ref>{{cite news |first=Jenny |last=Sinclair |title=Operation Chaos |url=http://www.theage.com.au/articles/2002/11/19/1037490107525.html |work=[[The Age]] |date=19 December 2002 |access-date=6 July 2007 |archive-date=29 April 2012 |archive-url=https://web.archive.org/web/20120429222024/http://www.theage.com.au/articles/2002/11/19/1037490107525.html |url-status=live }}</ref>

In 2000, the Government released a new Defence White Paper, ''Defence 2000&nbsp;– Our Future Defence Force'', that placed a greater emphasis on preparing the ADF for overseas deployments. The Government committed to improve the ADF's capabilities by improving the readiness and equipment of ADF units, expanding the ADF and increasing [[Real versus nominal value (economics)|real]] Defence expenditure by 3% per year;{{sfn|Thomson|2005|p=11}} in the event, expenditure increased by 2.3% per annum in real terms in the period to 2012–13.{{sfn|Thomson|2012|p=25}} In 2003 and 2005, the ''Defence Updates'' emphasised this focus on expeditionary operations and led to an expansion and modernisation of the ADF.{{sfn|Thomson|2006|pp=7–8}}

===Iraq and Afghanistan===
Since 2000, the ADF's expanded force structure and deployment capabilities have been put to the test on several occasions. Following the [[11 September attacks|11 September 2001 terrorist attacks]] on the United States, Australia committed a [[special forces]] task group and an [[air-to-air refuelling]] aircraft to operations in [[Afghanistan]], and naval warships to the Persian Gulf as [[Operation Slipper]].{{sfn|Dennis et al|2008|pp=8–9}} In 2003, approximately 2,000 ADF personnel, including a special forces task group, three warships and 14 [[F/A-18 Hornet]] aircraft, took part in the [[Australian contribution to the 2003 invasion of Iraq|invasion of Iraq]].{{sfn|Dennis et al|2008|p=248}}

The ADF was subsequently involved in the reconstruction of Iraq. From 2003 until 2005 this was mainly limited to a [[Security Detachment Iraq (Australia)|Security Detachment]] which protected the Australian embassy, the attachment of officers to multi-national headquarters, small numbers of transport and maritime patrol aircraft, and teams of air traffic controllers and medical personnel.<ref name="Fielding Concluding Australia's Military Commitment in Iraq">{{cite web|last1=Fielding|first1=Marcus|title=Concluding Australia's Military Commitment in Iraq|url=http://www.mhhv.org.au/?p=340|publisher=Military History and Heritage Victoria|access-date=31 December 2016|archive-date=31 December 2016|archive-url=https://web.archive.org/web/20161231170415/http://www.mhhv.org.au/?p=340|url-status=live}}</ref> From 2005 until 2008 a [[battalion]]-sized Australian Army battle group (initially designated the [[Al Muthanna Task Group]], and later [[Overwatch Battle Group (West)]]) was stationed in southern Iraq. In addition, teams of ADF personnel were deployed to train Iraqi military units. In line with a 2007 election commitment, the [[Rudd government (2007–10)|Rudd government]] withdrew combat-related forces from Iraq in mid-2008, and most of the remaining Australian units left the country the next year.<ref name="Fielding Concluding Australia's Military Commitment in Iraq" /><ref name="SBS Iraq timeline">{{cite web|title=Timeline: Australian troops in Iraq|url=http://www.sbs.com.au/news/article/2008/06/02/timeline-australian-troops-iraq|website=SBS News|publisher=SBS|access-date=31 December 2016|date=23 August 2013|archive-date=1 January 2017|archive-url=https://web.archive.org/web/20170101002610/http://www.sbs.com.au/news/article/2008/06/02/timeline-australian-troops-iraq|url-status=live}}</ref>

The ADF also undertook several operations in Australia's immediate region during the 2000s. In 2003, elements of all three services were dispatched to [[Solomon Islands]] as part of the [[Regional Assistance Mission to the Solomon Islands]]. Regular deployments of Australian forces continued to the islands until 2017.<ref>{{cite news|last1=O'Malley|first1=Nick|title=As RAMSI ends, Solomon Islanders look to the future|url=http://www.smh.com.au/world/as-ramsi-ends-solomon-islanders-look-to-the-future-20170621-gww2g1.html|access-date=14 January 2018|work=The Sydney Morning Herald|date=24 June 2017|archive-date=14 January 2018|archive-url=https://web.archive.org/web/20180114113447/http://www.smh.com.au/world/as-ramsi-ends-solomon-islanders-look-to-the-future-20170621-gww2g1.html|url-status=live}}</ref> Between December 2004 and March 2005, 1,400 ADF personnel served in Indonesia as part of [[Operation Sumatra Assist]], which formed part of Australia's response to the devastating [[2004 Indian Ocean earthquake]].{{sfn|Bullard|2017|p=512}} In May 2006, approximately 2,000 ADF personnel deployed to East Timor in [[Operation Astute]] following unrest between elements of the [[Timor Leste Defence Force]].{{sfn|Dennis et al|2008|p=193}} This deployment concluded in March 2013.<ref>{{cite news|last1=AAP|title=East Timor Operation Astute formally ends|url=http://www.theaustralian.com.au/news/latest-news/east-timor-operation-astute-formally-ends/news-story/ebd5a598fa73c0a97aecfa064036f4c2?sv=da978007173976bf54becf03bd690bb0|access-date=14 January 2018|work=The Australian|date=27 March 2013}}</ref>

From 2006 until 2013 a battalion-sized Australian Army task force operated in [[Urozgan Province]], Afghanistan; this unit was primarily tasked with providing assistance for reconstruction efforts and training Afghan forces, but was frequently involved in combat. In addition, Special Forces Task Groups were deployed from 2005 to 2006 and 2007 until 2013. Other specialist elements of the ADF, including detachments of [[Boeing CH-47 Chinook|CH-47 Chinook]] helicopters and RAAF radar and air traffic control units, were also periodically deployed to the country.<ref name="APH Afghanistan chronology as of 2010">{{cite web|last1=Brangwin|first1=Nicole|last2=Rann|first2=Anne|title=Australia's military involvement in Afghanistan since 2001: a chronology|url=http://www.aph.gov.au/About_Parliament/Parliamentary_Departments/Parliamentary_Library/pubs/BN/1011/MilitaryInvolvementAfghanistan|publisher=Parliament of Australia|access-date=31 December 2016|date=16 July 2010|archive-date=17 September 2014|archive-url=https://web.archive.org/web/20140917020242/http://www.aph.gov.au/About_Parliament/Parliamentary_Departments/Parliamentary_Library/pubs/BN/1011/MilitaryInvolvementAfghanistan|url-status=live}}</ref><ref name="APH Afghanistan facts and figures as of 2013">{{cite web|last1=Church|first1=Nathan|title=Australia at war in Afghanistan: updated facts and figures|url=http://www.aph.gov.au/About_Parliament/Parliamentary_Departments/Parliamentary_Library/pubs/rp/rp1314/AfghanistanFactsUpdated|publisher=Parliament of Australia|access-date=31 December 2016|date=13 December 2013|archive-date=31 December 2016|archive-url=https://web.archive.org/web/20161231170408/http://www.aph.gov.au/About_Parliament/Parliamentary_Departments/Parliamentary_Library/pubs/rp/rp1314/AfghanistanFactsUpdated|url-status=live}}</ref> A total of 40 ADF personnel were killed in Afghanistan between 2002 and 2013, and 262 wounded.<ref name="Defence Battle casualties in Afghanistan">{{cite web|title=Battle casualties in Afghanistan|url=http://www.defence.gov.au/operations/afghanistan/personnel.asp|publisher=Department of Defence|access-date=31 December 2016|archive-date=14 January 2017|archive-url=https://web.archive.org/web/20170114060656/http://defence.gov.au/Operations/Afghanistan/personnel.asp|url-status=live}}</ref> Following the withdrawal of the combat forces in 2013, ADF training teams have continued to be stationed in the country to train Afghan forces.<ref>{{cite web|title=Operation HIGHROAD|url=http://www.defence.gov.au/operations/afghanistan/|publisher=Department of Defence|access-date=31 December 2016|archive-date=1 January 2017|archive-url=https://web.archive.org/web/20170101001248/http://www.defence.gov.au/operations/afghanistan/|url-status=live}}</ref>

The [[Australian Labor Party]] (ALP) governments led by prime ministers [[Kevin Rudd]] and [[Julia Gillard]] between 2007 and 2013 commissioned two defence white papers, which were published in 2009 and 2013. The 2009 document, ''[[Defending Australia in the Asia Pacific Century: Force 2030]]'', had a focus on responding to China's rapidly growing influence. It included commitments to expand the RAN, including acquiring twelve submarines, and increasing defence spending by three percent per year in real terms. This increase in spending did not occur, however.{{sfn|Edwards|2016|pp=20–21}} The ''Defence White Paper 2013'' had similar strategic themes, but set out a more modest program of defence spending which reflected the government's constrained finances. As part of an election commitment, the  [[Coalition (Australia)|Liberal–National Coalition]] [[Abbott government]] commissioned a further defence white paper that was published in 2016.{{sfn|Edwards|2016|p=21}} This document also included a commitment to expand the ADF's size and capabilities.{{sfn|Thomson|2016|p=vi}} There has generally been [[bipartisan]] agreement between the ALP and the Liberal–National Coalition on the ADF's role since the mid-1970s. Both political groupings currently support the ADF's focus on expeditionary operations, and the broad funding target set out in the ''2016 Defence White Paper''.{{sfn|Thomson|2017|p=7}} The ADF's broad [[force structure]] has also experienced little change since the 1980s. For instance, throughout this period the Army's main combat formations have been three [[brigade]]s and the RAAF has been equipped with around 100 combat aircraft. Most of the equipment used by the services has been replaced or upgraded, however.{{sfn|Jennings|2016|pp=114, 137}}

It is stated in the ''2016 Defence White Paper'' that Australia's changing security environment will lead to new demands being placed on the Australian Defence Force. Although it is not expected that Australia will face any threat of direct attack from another country, terrorist groups and tensions between nations in East Asia pose threats to Australian security. More broadly, the Australian Government believes that it needs to make a contribution to maintaining the rules-based order globally. There is also a risk that [[climate change]], weak economic growth and social factors could cause instability in South Pacific countries.{{sfn|Australian Government|2016|pp=16–17}}

The ADF has developed strategies to respond to Australia's changing strategic environment. The ''2016 Defence White Paper'' states that "the Government will ensure Australia maintains a regionally superior ADF
with the highest levels of military capability and scientific and technological sophistication". To this end, the government intends to improve the ADF's combat power and expand the number of military personnel. This will include introducing new technologies and capabilities. The ADF is also seeking to improve its intelligence capabilities and co-operation between the services.{{sfn|Australian Government|2016|pp=18–20}}

Beginning in August 2014, RAAF combat forces, an Army special forces task force and an Army training unit were deployed to the Middle East during [[Operation Okra]] as part of the international [[war against the Islamic State]]. The RAAF aircraft conducted air strikes in Iraq and Syria and provided airborne command and control and air-to-air refuelling for the coalition forces. The special forces advised the [[Iraqi Army]] and the training unit trained Iraqi soldiers.<ref>{{cite web |last1=Westra |first1=Renee |title=Syria: Australian military operations |url=https://www.aph.gov.au/About_Parliament/Parliamentary_Departments/Parliamentary_Library/pubs/rp/rp1718/SyriaMilitaryOps |website=Parliamentary Library |publisher=Parliament of Australia |access-date=25 April 2023 |language=en-AU |date=20 September 2017}}</ref> The RAAF combat aircraft completed operations in January 2018, and the other aircraft were withdrawn in September 2020.<ref>{{cite news |title=RAAF completes last strike mission over Iraq |url=https://australianaviation.com.au/2018/01/raaf-completes-last-strike-mission-over-iraq/ |access-date=25 April 2023 |work=Australian Aviation |date=16 January 2018 |language=en-AU}}</ref><ref>{{cite web |title=Australian aircraft complete Middle East mission |url=https://www.minister.defence.gov.au/minister/lreynolds/media-releases/australian-aircraft-complete-middle-east-mission |website=Media release |publisher=Senator the Hon Linda Reynolds CSC |access-date=9 September 2020 |date=25 April 2023}}</ref> The Army training force departed in mid-2020.<ref>{{cite web |title=Task Group Taji operation a success |url=https://www.army.gov.au/our-news/media-releases/task-group-taji-operation-success |website=Media release |publisher=Australian Army |access-date=25 April 2023 |date=5 June 2020}}</ref>

The Australian Government believes that the country's strategic circumstances are worsening due to the threat posed by China. This has led to decisions to expand the ADF and enhance its ability to participate in high intensity combat. The ''2020 Defence Strategic Update'' called for the ADF's efforts to be focused on the [[Indo-Pacific]] region. It also concluded that there was no longer a ten-year period of strategic warning before Australia could be involved in a major war.

The election of the ALP [[Albanese government]] in May 2022 did not significantly change Australia's defence posture, as the ALP and Coalition parties have broadly similar defence policies. This includes an agreement on China posing a threat to Australia's security. The main difference is that the ALP sees [[climate change]] as an important security issue.<ref>{{cite news |last1=Hurst |first1=Daniel |title=Peter Dutton casts Coalition as stronger than Labor on defence as election nears – so how different are they? |url=https://www.theguardian.com/australia-news/2022/mar/19/peter-dutton-casts-coalition-as-stronger-than-labor-on-defence-as-election-nears-so-how-different-are-they |access-date=25 April 2023 |work=The Guardian |date=18 March 2022}}</ref>{{sfn|International Institute for Strategic Studies|2023|p=216}} After coming to power, the Albanese government commissioned the [[Defence Strategic Review]] that was publicly released in April 2023.

This includes transitioning the ADF from its traditional structure of a "balanced force" capable of a range of activities to a "focused force" tailored mainly to protecting Australia from military attack or [[coercion]]. As part of this change, the review recommended reducing the planned size of the Army's mechanised forces and expanding its long-range firepower.

Under the current ADF command structure the day-to-day management of the ADF is distinct from the command of military operations.{{sfn|Khosa|2011|p=13}} The services are administered through the ADO, with the head of each service (the [[Chief of Navy (Australia)|Chief of Navy]], [[Chief of Army (Australia)|Chief of Army]] and [[Chief of Air Force (Australia)|Chief of Air Force]]) and the service headquarters being responsible for raising, training and sustaining combat forces. Each chief is also the CDF's principal adviser on matters concerning the responsibilities of their service.

While the individual members of each service ultimately report to their service's Chief, the Chiefs do not control military operations. Control of ADF operations is exercised through a formal command chain headed by the CJOPS, who reports directly to the CDF. The CJOPS commands the [[Headquarters Joint Operations Command (Australia)|Headquarters Joint Operations Command]] (HQJOC) as well as temporary joint task forces. These joint task forces comprise units assigned from their service to participate in operations or training exercises.{{sfn|Khosa|2011|p=14}}{{sfn|Thomson|2017|p=35}}

Operational command of the ADF is exercised by HQJOC, which is located at a purpose-built facility near [[Bungendore, New South Wales|Bungendore]], New South Wales. This is a joint headquarters comprising personnel from the three services and includes a continuously manned Joint Control Centre. HQJOC's main role is to "plan, monitor and control" ADF operations and exercises, and it is organised around groups of plans, operations and support staff. HQJOC also monitors the readiness of the ADF units which are not assigned to operations and contributes to developing Australia's military doctrine.{{sfn|Khosa|2011|p=14}}

As well as HQJOC, the ADF has permanent joint operational commands responsible to the CJOPS. Joint Operations Command (JOC) includes the two headquarters responsible for patrolling Australia's maritime borders on a day-to-day basis, [[Northern Command (Australia)|Northern Command]] and [[Maritime Border Command (Australia)|Maritime Border Command]]. Other JOC units include the Joint Movements Group and the Air and Space Operations Centre. Individual ADF units and Joint Task Groups are assigned to JOC during operations, and HQJOC includes officers responsible for submarine and special operations forces.{{sfn|Khosa|2010|pp=13–15}}

In 2023, after the release of the [[Defence Strategic Review (DSR)]] and a recommendation to consolidate the ADF's guided weapons and explosive ordnance (GWEO) across the services, leading to the creation of the Guided Weapons and Explosive Ordnance Group (GWEOG), and the appointment of Air Marshal Leon Phillips, OAM as its head.

The ADF maintains stockpiles of ammunition, fuel and other supplies. Since the late 1990s, ammunition for the three services has been stored in a network of facilities managed by the JLC.{{sfn|Department of Defence|2017|p=1}} The creation of a GWEO Group moved the responsibility of acquisition and sustainment of Explosive Materiel within the ADF from JLC and CASG to itself.<ref>{{Cite web |title=Guided Weapons and Explosive Ordnance Enterprise {{!}} Business & Industry {{!}} Defence |url=https://www.defence.gov.au/business-industry/industry-capability-programs/guided-weapons-explosive-ordnance-enterprise |access-date=2024-02-17 |website=defence.gov.au}}</ref> The ADF also holds several months' worth of fuel for the Navy's vessels and several weeks' worth for aircraft and vehicles.

The increasing role of the [[private sector]] forms an important trend in the ADF's logistics arrangements. During the 1990s many of the ADF's support functions were transferred to the private sector to improve the efficiency with which they were provided. Since these reforms most of the "garrison" support services at military bases have been provided by [[Private military company|private firms]]. The reforms also led to many of the ADF's logistics units being disbanded or reduced in size.{{sfn|Horner|2001|pp=265–279}} Since this time private firms have increasingly been contracted to provide critical support to ADF units deployed outside Australia. This support has included transporting equipment and personnel and constructing and supplying bases.{{sfn|Thomson|2005a|pp=30–32}}

==Military intelligence and surveillance==
The Australian Defence Force's [[Military intelligence|intelligence]] collection and analysis capabilities include each of the services' intelligence systems and units, two joint civilian-military [[List of intelligence gathering disciplines|intelligence gathering]] agencies and two strategic and operational-level [[intelligence analysis]] organisations.{{sfn|Horner|2001|p=150}}<ref>{{cite web|title=The Australian Intelligence Community|url=https://www.igis.gov.au/australian-intelligence-community|publisher=Inspector-General of Intelligence and Security|access-date=8 January 2018|archive-date=23 February 2019|archive-url=https://web.archive.org/web/20190223020420/https://www.igis.gov.au/australian-intelligence-community|url-status=dead}}</ref>

Each of the three services has its own intelligence collection assets.{{sfn|Horner|2001|p=150}} RAN doctrine stresses the importance of collecting a wide range of information and combining it to inform decisions.

The [[Defence Intelligence and Security Group|Defence Strategic Policy and Intelligence Group]] within the Department of Defence supports the services and co-operates with the civilian agencies within the [[List of Australian intelligence agencies|Australian Intelligence Community]]. This Group consists of the [[Australian Geospatial-Intelligence Organisation]] (AGO), [[Australian Signals Directorate]] (ASD) and [[Defence Intelligence Organisation]] (DIO). The AGO is responsible for [[GEOINT|geospatial intelligence]] and producing maps for the ADF, the ASD, originally the Defence Signals Directorate, is Australia's [[signals intelligence]] agency, and the DIO is responsible for the analysis of intelligence collected by the other intelligence agencies. The three agencies are headquartered in Canberra, though the AGO has staff in [[Bendigo, Victoria|Bendigo]] and the ASD maintains permanent signals collection facilities in other locations.{{sfn|Khosa|2011|p=125}}

The ASD also includes the [[Australian Intelligence Community#Australian Cyber Security Centre|Australian Cyber Security Centre]] (ACSC) which is responsible for protecting Defence and other Australian Government agencies against [[cyberwarfare]] attacks.

[[Demographics of Australia|Australian demographic trends]] will put pressure on the ADF in the future.{{sfn|Henry|2005|p=19}} Excluding other factors, the ageing of the Australian population will result in smaller numbers of potential recruits entering the Australian [[labour market]] each year. Some predictions are that population ageing will result in slower economic growth and increased government expenditure on pensions and health programs. As a result of these trends, the ageing of Australia's population may worsen the ADF's manpower situation and may force the Government to reallocate some of the Defence budget.{{sfn|Henry|2005|pp=22–23}} Few young Australians consider joining the military and the ADF has to compete for recruits against private sector firms which are able to offer higher salaries.{{sfn|Grey|2008|p=280}}

The number of ADF personnel has changed over the last 20 years. During the 1990s the strength of the ADF was reduced from around 70,000 to 50,000 permanent personnel as a result of budget cuts and the outsourcing of some military functions. The ADF began to grow from 2000 after the defence white paper released that year called for an expansion to the military's strength, though the size of the military decreased between the 2003–04 to 2005–06 financial years due to problems with attracting further recruits. By 2009–10 the ADF was above its budgeted size, leading to reductions until 2014–15. The size of the ADF grew between the 2014–15 and 2016–17 financial years.{{sfn|Thomson|2017|p=64}} The ADF has not met its recruitment targets over the period since the 1995–96 financial year.{{sfn|Thomson|2017|p=65}}

Whilst the ADF is the largest military in Oceania,{{sfn|Hardy|2013|p=195}} it is small compared to most Asian military forces ranking 8th out of 27 countries in Asia in 2024 according to the [[Lowy Institute]].<ref>{{cite news |last1=Vyas |first1=Heloise |title=Australia has become more powerful in Asia as Russia's influence falters.

Both the number of personnel in the ADF and the share of the Australian population this represents is smaller than that in many countries in Australia's immediate region. Several [[NATO]] member countries, including France and the United States, also have a higher share of their population in the military.{{sfn|Thomson|2005|pp=4–5}} This is a continuation of long-term trends, as outside of major wars Australia has always had a relatively small military. The size of the force is a result of Australia's relatively small population and the military being structured around a maritime strategy focused on the RAN and RAAF rather than a manpower-intensive army.{{sfn|Thomson|2005|p=5}}{{sfn|Australian Government|2014|p=33}}

In March 2022, Prime Minister Scott Morrison announced that by 2040 the strength of the ADF would grow by around 30% to be almost 80,000 permanent personnel. The expansion is estimated to cost at least A$38 billion which includes increasing the number of APS personnel.<ref>{{cite press release |author1=Prime Minister Scott Morrison |title=Defence workforce to grow above 100,000 |url=https://www.pm.gov.au/media/defence-workforce-grow-above-100000 |website=Prime Minister of Australia |date=10 March 2022}}</ref><ref>{{cite news |last1=Hellyer |first1=Marcus |title=Where will Defence find 18,500 more people? |url=https://www.aspistrategist.org.au/where-will-defence-find-18500-more-people/ |access-date=7 May 2022 |work=The Strategist |publisher=The Australian Strategic Policy Institute |date=17 March 2022}}</ref>

===Reserves===

Each of the branches of the ADF has a reserve component. These forces are the [[Royal Australian Naval Reserve]], [[Australian Army Reserve]] and [[Royal Australian Air Force Reserve]].{{sfn|Australian National Audit Office|2001|p=11}} The main role of the reserves is to supplement the permanent elements of the ADF during deployments and crises, including [[natural disaster]]s. This can include attaching individual reservists to regular units or deploying units composed entirely of reserve personnel.{{sfn|Australian National Audit Office|2001|p=29}} As reservists serve on a part-time basis, they are less costly to the government than permanent members of the ADF, but the nature of their service can mean that reservists have a lower level of readiness than regular personnel and require further training before they can be deployed.{{sfn|Australian National Audit Office|2001|p=30}} It has historically proven difficult to set a level of training requirements which allows reservists to be rapidly deployable yet does not act as a disincentive to recruitment and continued participation.{{sfn|Dennis et al|2008|p=46}} Successive governments since the 1960s have also been reluctant to use the "call out" powers to require reservists to undertake active service.<ref>{{cite web|last1=Smith|first1=Hugh|title=A 'total force' at last?

There are two main categories of reserve personnel; those in the active reserve and those in the standby reserve.<ref name="Year_Book_Aust_2009-10_people">{{cite web |author=Australian Bureau of Statistics |year=2010 |title=People |url=http://www.abs.gov.au/AUSSTATS/abs@.nsf/Lookup/6D4CD661FDBA3226CA25773700169C59?opendocument |url-status=live |archive-url=https://web.archive.org/web/20110312161143/http://abs.gov.au/AUSSTATS/abs@.nsf/Lookup/6D4CD661FDBA3226CA25773700169C59?opendocument |archive-date=12 March 2011 |access-date=18 July 2010 |work=Year Book Australia, 2009–10 |publisher=Australian Bureau of Statistics |location=Canberra}}</ref> Members of the active reserve have an annual minimum training obligation.{{sfn|Australian National Audit Office|2001|p=31}} Reservists can volunteer to undertake more than the minimum periods of training and active service.{{sfn|Defence People Group|2017|p=6}} Members of the standby reserve are not required to undertake training, and would only be called up in response to a national emergency or to fill a specialised position. Most standby reservists are former full-time members of the ADF.{{sfn|Australian National Audit Office|2001|p=58}}{{sfn|Defence People Group|2017|p=11}}

While Australian Naval Reserve personnel are assigned to permanent units, most members of the Army Reserve and Air Force Reserve are members of reserve units. Most of the RAAF's reserve units are not intended to be deployed, and reserve personnel are generally attached to regular air force units during their periods of active service.{{sfn|Australian National Audit Office|2001|pp=36, 61, 65, 76}}<ref>{{cite web|title=Air Force Reserves|date=3 November 2017|url=https://www.airforce.gov.au/our-people/careers/reserves|publisher=Royal Australian Air Force|access-date=26 January 2018|archive-date=27 January 2018|archive-url=https://web.archive.org/web/20180127084046/https://www.airforce.gov.au/our-people/careers/reserves|url-status=live}}</ref> The Army Reserve is organised into permanent combat and support units, though most are currently manned at levels well below their authorised strengths and are not capable of deploying as formed units.{{sfn|Smith|2014|pp=42–43}}

The ADF's increased activities since 1999 and shortfalls in recruiting permanent personnel has led to reservists being more frequently called to active service.{{sfn|Grey|2008|p=280}} This has included large scale domestic deployments, which have included providing security for major events such as the [[2000 Summer Olympics]] and responding to natural disasters. Large numbers of reserve personnel have also been deployed as part of ADF operations in Australia's region; this has included the deployment of Army Reserve [[Company (military unit)|rifle companies]] to East Timor and the Solomon Islands. Smaller numbers of reservists have taken part in operations in locations distant from Australia.{{sfn|Department of Defence|2009|p=90}} Notably, companies of the Army Reserve 1st Commando Regiment were regularly deployed to Afghanistan as part of the Special Operations Task Group.<ref>{{cite web|title=1st Commando Regiment|url=https://www.army.gov.au/our-people/units/special-operations-command/1st-commando-regiment|publisher=Australian Army|access-date=31 December 2017|archive-date=31 December 2017|archive-url=https://web.archive.org/web/20171231103353/https://www.army.gov.au/our-people/units/special-operations-command/1st-commando-regiment|url-status=live}}</ref>

===Training===
[[File:ADFA Aerial.jpg|thumb|The Australian Defence Force Academy in Canberra]]
Individual training of Australian servicemen and women is generally provided by the services in their own training institutions. Each service has its own training organisation to manage this individual training. Where possible, however, individual training is increasingly being provided through tri-service schools.{{sfn|Horner|2001|p=281}}

Military academies include {{HMAS|Creswell}} for the Navy, [[Royal Military College, Duntroon]], for the Army, and the [[Officers' Training School RAAF|Officers' Training School]] for the Air Force. The [[Australian Defence Force Academy]] is a tri-service university for officer cadets of all services who wish to attain a university degree through the ADF. Navy recruit training is conducted at {{HMAS|Cerberus|naval base|6}}, Army recruits are trained at the [[Army Recruit Training Centre]] and Air Force recruits at [[RAAF Base Wagga]].{{sfn|Horner|2001|pp=294–301}}

===Women in the ADF===
{{Main|Women in the Australian military}}
Women first served in the Australian military during World War II when each service established a separate female branch. The RAAF was the first service to fully integrate women into operational units, doing so in 1977, with the Army and RAN following in 1979 and 1985 respectively.{{sfn|Horner|2001|pp=321–324}} The ADF initially struggled to integrate women, with integration being driven by changing Australian social values and Government legislation rather than a change in attitudes within the male-dominated military.{{sfn|Beaumont|2001|p=357}}

The number of positions available to women in the ADF has increased over time. Although servicewomen were initially barred from combat positions, these restrictions began to be lifted in 1990.{{sfn|Foreign Affairs, Defence and Trade Group|2000}} In September 2011 Minister for Defence Stephen Smith announced that the Cabinet had decided to remove all restrictions on women serving in combat positions, and that this change would come into effect within five years. This decision was supported by the CDF and the chiefs of the services.<ref>{{cite news|last=Thompson|first=Jeremy|title=Women cleared to serve in combat|url=http://www.abc.net.au/news/2011-09-27/women-on-the-frontline/2946258|date=27 September 2011|access-date=27 September 2011|newspaper=ABC News|archive-date=27 September 2011|archive-url=https://web.archive.org/web/20110927222526/http://www.abc.net.au/news/2011-09-27/women-on-the-frontline/2946258|url-status=live}}</ref> Serving women became able to apply for all positions on 1 January 2013 except special forces roles in the Army which became open to women in January 2014.<ref name="Lifting of gender restrictions">{{cite press release|title=Lifting of gender restrictions in the Australian Defence Force|url=http://news.defence.gov.au/2013/02/01/lifting-of-gender-restrictions-in-the-australian-defence-force/|publisher=Department of Defence|date=1 February 2013|access-date=3 February 2013|url-status=dead|archive-url=https://web.archive.org/web/20130324001506/http://news.defence.gov.au/2013/02/01/lifting-of-gender-restrictions-in-the-australian-defence-force/|archive-date=24 March 2013|df=dmy-all}}</ref><ref name="Johnston2014">{{cite speech |author1=Minister for Defence, Senator David Johnston |title=Minister for Defence – Opening address - Defence Women in Peace and Security Conference |url=https://www.minister.defence.gov.au/minister/david-johnston/speeches/minister-defence-opening-address-defence-women-peace-and-security |event=2014 Defence Women in Peace and Security Conference |access-date=15 March 2021 |date=16 June 2014 |archive-date=24 April 2021 |archive-url=https://web.archive.org/web/20210424214941/https://www.minister.defence.gov.au/minister/david-johnston/speeches/minister-defence-opening-address-defence-women-peace-and-security |url-status=live }}</ref> In January 2016, civilian women became able to be directly recruited to all positions.<ref>{{cite press release |title=Landmark moment for women in the ADF |url=https://www.pmc.gov.au/news-centre/office-women/landmark-moment-women-adf |website=Department of the Prime Minister and Cabinet |access-date=15 March 2021 |date=24 October 2018 |archive-date=14 March 2021 |archive-url=https://web.archive.org/web/20210314153441/https://pmc.gov.au/news-centre/office-women/landmark-moment-women-adf |url-status=live }}</ref>

Despite the expansion in the number of positions available to women and other changes which aim to encourage increased female recruitment and retention, the growth in the proportion of female permanent defence personnel has been slow.{{sfn|Thomson|2017|p=80}} In the 1989–1990 financial year women made up 11.4% of the ADF personnel. In the 2008–2009 financial year women occupied 13.5% of ADF positions. During the same period the proportion of civilian positions filled by women in the Australian Defence Organisation increased from 30.8% to 42.8%.{{sfn|Khosa|2010|p=79}} In 2023–2024, women made up 20.7% of the ADF's permanent force. The proportion of women in the permanent force differs by service: 15.3% of members of the Army are women, compared to 24.1% of the RAN and 27% for the RAAF.{{sfn|Department of Defence|2025b|p=9}} In 2024, the ADF adopted targets to increase the proportion of women in the ADF's permanent force to 25% by 2030 and the proportion of women in the services by 2030 of: 28% in the RAN, 18% in the Army and 35% in the RAAF.{{sfn|Department of Defence|2025b|p=11}}<ref>{{cite news |last1=Powell |first1=Sian |title=ADF aims for more women to serve by 2030 |url=https://www.theaustralian.com.au/special-reports/defence/adf-aims-for-more-women-to-serve-by-20300/news-story/1fc1f9405e17dfcef28b9bbd9b20669a |access-date=9 November 2025 |work=[[The Australian]] |publisher=[[News Corp Australia]] |date=16 October 2025}}</ref>

There continue to be concerns over the incidence of sexual abuse and gender-based discrimination in the ADF. In 2014 the [[Defence Abuse Response Taskforce]] estimated that around 1,100 currently-serving ADF personnel had abused other members of the military, and recommended that a [[royal commission]] be conducted to investigate long-running allegations of sexual abuse and assault of servicewomen at the Australian Defence Force Academy.<ref name="Government to seriously consider call for royal commission">{{cite news|last1=Wroe|first1=David|title=Defence abuse: Government to 'seriously' consider call for royal commission into abuse at the Australian Defence Force Academy|url=http://www.smh.com.au/federal-politics/political-news/defence-abuse-government-to-seriously-consider-call-for-royal-commission-into-abuse-at-the-australian-defence-force-academy-20141126-11u1jq.html|access-date=5 December 2014|work=The Sydney Morning Herald|date=26 November 2014|archive-date=28 November 2014|archive-url=https://web.archive.org/web/20141128184620/http://www.smh.com.au/federal-politics/political-news/defence-abuse-government-to-seriously-consider-call-for-royal-commission-into-abuse-at-the-australian-defence-force-academy-20141126-11u1jq.html|url-status=live}}</ref> In 2013 Chief of Army General David Morrison publicly released a video in which he warned against gender-based discrimination, and stated that he would dismiss members of the Army who engaged in such conduct.<ref name="Morrison tells troops to respect women or get out">{{cite news|title=Chief of Army David Morrison tells troops to respect women or 'get out'|url=http://www.abc.net.au/news/2013-06-14/chief-of-army-fires-broadside-at-army-over-email-allegations/4753208|access-date=5 December 2014|work=ABC News|date=14 June 2014|archive-date=4 January 2015|archive-url=https://web.archive.org/web/20150104021115/http://www.abc.net.au/news/2013-06-14/chief-of-army-fires-broadside-at-army-over-email-allegations/4753208|url-status=live}}</ref>

===Ethnic and religious composition===
[[File:RAAF airman constructing a Joint Direct Attack Munition in February 2017.jpg|thumb|alt=A man wearing a blue T-shirt with a military logo working on a green bomb|A RAAF airman assembling a bomb]]
A high percentage of ADF personnel are drawn from the [[Anglo-Celtic Australian|Anglo-Celtic]] portion of Australia's population. In 2011 the proportion of ADF personnel born in Australia and the other predominately Anglo-Celtic countries was higher than this population group's share of both the Australian workforce and overall population.{{sfn|Thomson|2017|pp=77–79}} As a result, analyst Mark Thomson has argued that the ADF is unrepresentative of Australia's society in this regard and that recruiting more personnel from other ethnic backgrounds would improve the ADF's language skills and cultural empathy.{{sfn|Thomson|2009|pp=47–49}} In 2013, the ADF launched the ''Defence Diversity and Inclusion Strategy 2012-2017'' to recruit more volunteers from culturally and linguistically diverse backgrounds and to improve statistics collection.{{sfn|Defence People Group|2014|pp=18–19}}

On 30 June 2025, 3.9% of ADF permanent personnel and 3.0% of Reserves were [[Indigenous Australians]].{{sfn|Department of Defence|2025a|p=147}} The ''[[Reconciliation Action Plan|Defence Reconciliation Action Plan 2019-2022]]'' had aimed to increase the number of Indigenous Australians the ADF recruits and to improve their retention rate, and had set a target of 5% Indigenous representation by 2025.{{sfn|Department of Defence|2020|p=105}} Restrictions on Indigenous Australians' ability to enlist in the military existed until the 1970s, though hundreds of Indigenous men and women had joined the military when restrictions were reduced during the world wars. By 1992 the representation of Indigenous Australians in the ADF was equivalent to their proportion of the Australian population, though they continue to be under-represented among the officer corps. Two of the Army's three Regional Force Surveillance Units ([[NORFORCE]] and the [[Far North Queensland Regiment|51st Battalion, Far North Queensland Regiment]]) are manned mostly by Indigenous Australian reservists.{{sfn|Dennis et al|2008|pp=3–5}} In 2015 Indigenous Australians made up around 2% of ADF personnel, which was smaller than the Indigenous share of the total Australian population.{{sfn|Thomson|2017|pp=78–79}}

In line with trends across the broader Australian population, the proportion of ADF personnel who are not religious has increased considerably over recent years. The proportion of ADF personnel who reported that their religion was Christianity in service censuses and human relations databases decreased from around 66% in 2003 to just over 52% in 2015. Over this period, the proportion who stated that they do not have a religious affiliation increased from 31% to 47%. Only 1% of ADF members reported having a non-Christian religious affiliation in 2015.{{sfn|Hoglin|2016|pp=20–23}} In 2023 it was reported that 80% of new ADF recruits did not have religious beliefs.<ref>{{cite news |last1=Shepherd |first1=Tory |title=ADF has 108 evangelical chaplains with each representing just 15 members |url=https://www.theguardian.com/australia-news/2023/jul/30/adf-has-108-evangelical-chaplains-with-each-representing-just-15-members |access-date=30 July 2023 |work=The Guardian |date=30 July 2023}}</ref>

{{Main|Sexual orientation and gender identity in the Australian military}}
Australia allows gay men and lesbians to serve openly. Openly gay and lesbian personnel were banned from the ADF until November 1992 when the Australian Government decided to remove this prohibition. The heads of the services and most military personnel opposed this change at the time, and it caused considerable public debate.{{sfn|Grey|2008|p=275}}{{sfn|Dennis et al|2008|p=264}} Opponents of lifting the ban on gay and lesbian personnel argued that doing so would greatly harm the ADF's cohesiveness and cause large numbers of resignations. This did not eventuate, and the reform caused few problems.{{sfn|Dennis et al|2008|pp=264–265}} A 2000 study found that lifting the ban on gay service did not have any negative effects on the ADF's morale, effectiveness or recruitment and retention, and may have led to increased productivity and improved working environments.{{sfn|Belkin|McNichol|2000|pp=2–3}} Few members of the ADF [[Coming out|came out]] as lesbian, gay or bisexual until the late 1990s, however, and those who did were not always welcomed by their comrades.{{sfn|Riseman|2018|pp=36–38}}

ADF personnel in same-sex relationships experienced discriminatory treatment until the 2000s. This included Defence not recognising same-sex spouses, which prevented these couples from receiving the financial entitlements available to opposite-sex couples and could be a barrier to the spouse being treated as their partner's [[next of kin]].{{sfn|Riseman|2018|p=38}} The ADF officially recognised same-sex relationships in 2005, and since 1 January 2009 these couples [[Same-sex unions and military policy#Australia|have had the same access]] to military retirement pensions and superannuation as opposite-sex couples.{{sfn|Riseman|2018|p=41}}<ref>{{cite news|title=Defence law changes recognise same-sex couples|url=http://abc.gov.au/news/stories/2008/12/18/2450532.htm?site=news|access-date=5 September 2010|work=ABC News|date=18 December 2010|archive-date=5 November 2011|archive-url=https://web.archive.org/web/20111105154651/http://abc.gov.au/news/stories/2008/12/18/2450532.htm?site=news|url-status=live}}</ref> [[Transgender]] personnel have been permitted to serve in the ADF since 2010, and are provided with support when necessary.{{sfn|Riseman|2018|pp=42–43}}<ref>{{cite news|last=Farr|first=Malcolm|title=Army leader General David Morrison wants to defeat sexism|url=http://www.news.com.au/national-news/army-leader-general-david-morrison-wants-to-defeat-sexism-after/story-fncynjr2-1226663795362|access-date=16 June 2013|newspaper=News.com.au|date=14 June 2013|archive-date=15 June 2013|archive-url=https://web.archive.org/web/20130615022637/http://www.news.com.au/national-news/army-leader-general-david-morrison-wants-to-defeat-sexism-after/story-fncynjr2-1226663795362|url-status=live}}</ref> Despite the removal of restrictions on gay and lesbian personnel, harassment and discrimination continued to occur; for instance a 2013 survey found that 10% of gay soldiers had experienced discrimination and more than 30% hid their sexuality.<ref>{{cite news|last1=McPhedran|first1=Ian|title=Gay soldiers safe from harassment but hide sexuality, survey finds|url=http://www.news.com.au/national/gay-soldiers-safe-from-harassment-but-hide-sexuality-survey-finds/news-story/fd40b4ae74f3409ebe33a332675ff45f|access-date=1 January 2018|work=news.com.au|date=9 September 2013|archive-date=15 October 2017|archive-url=https://web.archive.org/web/20171015172513/http://www.news.com.au/national/gay-soldiers-safe-from-harassment-but-hide-sexuality-survey-finds/news-story/fd40b4ae74f3409ebe33a332675ff45f|url-status=live}}</ref> The ADF has actively encouraged the inclusion of LGBTI personnel since the mid-2010s, with its leadership highlighting the importance of the issue and the military justice system being strongly used to prevent harassment and discrimination.

The Royal Australian Navy has two main bases; [[Fleet Base East]] (HMAS ''Kuttabul'') in Sydney and [[Fleet Base West]] (HMAS ''Stirling'') near Perth. The Navy's operational headquarters, Fleet Headquarters, is located adjacent to Fleet Base East. The majority of the Navy's patrol boats are based at {{HMAS|Coonawarra}} in [[Darwin, Northern Territory|Darwin]], Northern Territory, with the remaining patrol boats and the hydrographic fleet located at {{HMAS|Cairns|naval base|6}} in [[Cairns]].

The Australian Army's regular units are concentrated in a few bases, most of which are located in Australia's northern states. The Army's operational headquarters, Forces Command, is located at [[Victoria Barracks, Sydney|Victoria Barracks]] in Sydney. Most elements of the Army's three regular brigades are based at [[Robertson Barracks]] near Darwin, [[Lavarack Barracks]] in [[Townsville]], Queensland, and [[Gallipoli Barracks]] in Brisbane. The 1st Division's Headquarters is also located at Gallipoli Barracks. Other important Army bases include the [[Oakey Army Aviation Centre|Army Aviation Centre]] near [[Oakey, Queensland|Oakey]], Queensland, [[Holsworthy Barracks]] near Sydney, [[Woodside Barracks]] near [[Adelaide, South Australia|Adelaide]], South Australia, and [[Campbell Barracks (Australia)|Campbell Barracks]] in Perth.

The Royal Australian Air Force maintains several air bases, including three which are only occasionally activated. The RAAF's operational headquarters, [[RAAF Air Command|Air Command]], is located at [[RAAF Base Glenbrook]] near Sydney. The Air Force's combat aircraft are based at [[RAAF Base Amberley]] near [[Ipswich, Queensland|Ipswich]], Queensland, [[RAAF Base Tindal]] near [[Katherine, Northern Territory|Katherine]], Northern Territory, and [[RAAF Base Williamtown]] near [[Newcastle, New South Wales|Newcastle]], New South Wales. The RAAF's maritime patrol aircraft are based at [[RAAF Base Edinburgh]] near Adelaide and most of its transport aircraft are based at [[RAAF Base Richmond]] in Sydney. RAAF Base Edinburgh is also home to the control centre for the [[Jindalee Operational Radar Network]]. Most of the RAAF's training aircraft are based at [[RAAF Base Pearce]] near Perth with the remaining aircraft located at [[RAAF Base East Sale]] near [[Sale, Victoria|Sale]], Victoria, and RAAF Base Williamtown. The RAAF also maintains a network of bases in northern Australia to support operations to Australia's north.

In addition to its military role, the ADF contributes to domestic security as well as disaster relief efforts in Australia and overseas. These functions are primarily the responsibility of civilian agencies, and the ADF's role in them requires specific justification and authorisation.{{sfn|Dennis et al|2008|p=178}}

Elements of the ADF are frequently [[Military aid to the civil power|called out]] to contribute to relief efforts following natural disasters in Australia or overseas. The ADF's role in these efforts is set out in Australia's emergency management plans. The ADF typically contributes specialist capabilities, such as engineers or transport, to support the civil authorities.{{sfn|Australian National Audit Office|2014|pp=11–13, 39}} For major disasters, this can involve a large-scale deployment of personnel and assets. While the ADF has a commitment to assist relief efforts, several defence white papers have specified that this is a secondary responsibility to the force's focus on maintaining combat capabilities. As a result, requests for assistance have to be balanced against military priorities.{{sfn|Australian National Audit Office|2014|pp=30–31}} No elements of the ADF are specifically tasked with or equipped for disaster relief efforts.{{sfn|Australian National Audit Office|2014|p=39}}

The ADF can also be tasked with providing aid to civil authorities outside of natural disasters; for instance in response to [[industrial action]] or to assist civilian police maintain law and order. This rarely occurs, however, and most Australians consider the use of military personnel to break strikes or undertake law enforcement to be inappropriate.<ref>{{cite web|last1=Ward|first1=Elizabeth|title=Call Out the Troops: an examination of the legal basis for Australian Defence Force involvement in 'non-defence' matters|url=http://www.aph.gov.au/About_Parliament/Parliamentary_Departments/Parliamentary_Library/pubs/rp/RP9798/98rp08|publisher=Parliament of Australia|access-date=1 January 2017|date=1997|archive-date=1 January 2017|archive-url=https://web.archive.org/web/20170101232155/http://www.aph.gov.au/About_Parliament/Parliamentary_Departments/Parliamentary_Library/pubs/rp/RP9798/98rp08|url-status=live}}</ref>{{sfn|Sutton|2017|pp=42}} Due to the political sensitivities associated with strike breaking, the ADF conducts little planning or other preparations for this role and the ''Defence Act'' explicitly states that reservists may not be called out or deployed in response to industrial action.{{sfn|Dennis et al|2008|p=179}}

The scale of these deployments and the disruption they have caused to military training has led to suggestions that either elements of the Army Reserve be dedicated to disaster relief or a separate civilian organisation be established to take on the duties the ADF is undertaking.<ref>{{cite news |last1=Heanue |first1=Siobhan |title=Putting troops on the frontline of pandemics, natural disasters means less time to train for war |url=https://www.abc.net.au/news/2020-08-27/troops-on-pandemic-bushfire-frontline-cant-train-for-war/12593126 |access-date=29 August 2020 |work=ABC News |date=27 August 2020 |archive-date=17 January 2021 |archive-url=https://web.archive.org/web/20210117191624/https://www.abc.net.au/news/2020-08-27/troops-on-pandemic-bushfire-frontline-cant-train-for-war/12593126 |url-status=live }}</ref><ref>{{cite news |last1=RMIT ABC Fact Check |title=How is the Australian Defence Force assisting states during COVID-19? |url=https://www.abc.net.au/news/2020-08-12/fact-check-defence-force-coronavirus-fact-file-hotel-quarantine/12522492?nw=0 |access-date=29 August 2020 |work=ABC News |date=12 August 2020 |archive-date=28 August 2020 |archive-url=https://web.archive.org/web/20200828143206/https://www.abc.net.au/news/2020-08-12/fact-check-defence-force-coronavirus-fact-file-hotel-quarantine/12522492?nw=0 |url-status=live }}</ref>

The ADF makes a significant contribution to Australia's domestic maritime security. ADF ships, aircraft and Regional Force Surveillance Units conduct patrols of northern Australia in conjunction with the [[Australian Border Force]] (ABF). This operation, which is code-named [[Operation Resolute]], is commanded by the [[Maritime Border Command (Australia)|Maritime Border Command]] which is jointly manned by members of the ADF and ABF. This operation involves a considerable proportion of the ADF's assets, with the forces assigned typically including two major naval vessels, multiple patrol boats, Regional Force Surveillance Unit patrols and AP-3 Orion aircraft.<ref>{{cite web|title=Operation Resolute|url=http://www.defence.gov.au/Operations/BorderProtection/default.asp|publisher=Department of Defence|access-date=2 January 2017|archive-date=13 January 2017|archive-url=https://web.archive.org/web/20170113191911/http://defence.gov.au/Operations/BorderProtection/default.asp|url-status=live}}</ref> The ADF also often contributes to [[search and rescue]] efforts coordinated by the [[Australian Maritime Safety Authority]] and other civilian agencies.{{sfn|Dennis et al|2008|p=178}}<ref>{{cite web|title=Search and rescue arrangements in Australia|url=https://www.amsa.gov.au/safety-navigation/search-and-rescue/search-and-rescue-arrangements-australia|publisher=Australian Maritime Safety Authority|access-date=16 January 2018|archive-date=17 January 2018|archive-url=https://web.archive.org/web/20180117132735/https://www.amsa.gov.au/safety-navigation/search-and-rescue/search-and-rescue-arrangements-australia|url-status=live}}</ref>

While the ADF does not have a significant nation-building role, it provides assistance to remote [[Indigenous Australian]] communities through the [[Army Aboriginal Community Assistance Program]]. Under this program, which has been conducted since 1997, an [[Royal Australian Engineers|engineer squadron]] works with one community for several months each year to upgrade local infrastructure and provide training.<ref>{{cite web|title=Army Indigenous Initiatives|url=https://www.army.gov.au/our-people/army-indigenous-community/army-indigenous-initiatives|publisher=Australian Army|access-date=31 December 2017|archive-date=1 January 2018|archive-url=https://web.archive.org/web/20180101135258/https://www.army.gov.au/our-people/army-indigenous-community/army-indigenous-initiatives|url-status=live}}</ref> The ADF also took part in the [[Northern Territory National Emergency Response|intervention in remote Northern Territory Indigenous communities]] between June 2007 and October 2008. During this operation more than 600 ADF personnel provided logistical support to the Northern Territory Emergency Response Task Force and helped conduct child health checks.<ref>{{cite news|title=Military to end role in NT intervention|url=http://www.smh.com.au/national/military-to-end-role-in-nt-intervention-20081031-5f8i.html|access-date=31 December 2017|work=The Sydney Morning Herald|date=31 October 2008|archive-date=1 January 2018|archive-url=https://web.archive.org/web/20180101082433/http://www.smh.com.au/national/military-to-end-role-in-nt-intervention-20081031-5f8i.html|url-status=live}}</ref>

The ADF shares responsibility for [[counter-terrorism]] with civilian law enforcement agencies. Under ''Australia's Counter-Terrorism Strategy'', the [[Law enforcement in Australia|state and territory police]] and emergency services have the primary responsibility for responding to any terrorist incidents on Australian territory. If a terrorist threat or the consequences of an incident are beyond the capacity of civilian authorities to resolve, the ADF may be called out to provide support following a request from the relevant state or territory government. The Commonwealth Government has responsibility for responding to offshore terrorist incidents.{{sfn|Council of Australian Governments|2015|p=17}} ADF liaison officers are posted to civilian law enforcement agencies, and the military offers specialised training to police counter-terrorism teams.<ref>{{cite news|last1=Greene|first1=Andrew|title=Defence Force to take greater role in responding to domestic terrorism|url=http://www.abc.net.au/news/2017-07-17/defence-to-take-greater-role-in-domestic-terrorism-response/8713868|access-date=31 December 2017|work=ABC News|date=17 July 2017|archive-date=25 January 2018|archive-url=https://web.archive.org/web/20180125122907/http://www.abc.net.au/news/2017-07-17/defence-to-take-greater-role-in-domestic-terrorism-response/8713868|url-status=live}}</ref> To meet its counter-terrorism responsibilities the ADF maintains two elite [[Tactical Assault Group (Australia)|Tactical Assault Groups]], the Special Operations Engineer Regiment as well as a company-sized high readiness group in each [[Australian Army Reserve|Army Reserve]] brigade and the [[1st Commando Regiment]]. ADF intelligence assets also work with other Australian Government and police agencies to counter foreign terrorist threats.{{sfn|Smith|Bergin|2006|p=7}}{{sfn|Australian Government|2016|p=72}} While these forces provide a substantial counter-terrorism capability, the ADF does not regard domestic security as being part of its "core business".{{sfn|Smith|Bergin|2006|p=13}}
