Territorial evolution of Australia
Template:Use Australian English Template:Use dmy dates Template:Short description
The first colonies of the British Empire on the continent of Australia were the penal colony of New South Wales, founded in 1788, and the Swan River Colony (later renamed Western Australia), founded in 1829. Over the next few decades, the colonies of New Zealand, Queensland, South Australia, Van Diemen's Land (later renamed Tasmania), and Victoria were created from New South Wales, as well as an aborted Colony of North Australia. On 1 January 1901, these colonies, excepting New Zealand, became states in the Commonwealth of Australia. Since federation, the internal borders have remained mostly stable, except for the creation of some territories with limited self-government: the Northern Territory from South Australia, to govern the vast, sparsely populated centre of the country; the split of the Northern Territory into Central Australia and North Australia, and then the quick merger of those back into the Northern Territory; and the Australian Capital Territory, a federal district ceded from New South Wales.
Outside of the continent, Queensland attempted an expansion into New Guinea, but British authorities rejected this; the claim would later be made a British protectorate and ceded to Australia. The League of Nations mandated northeast New Guinea to Australia after World War I, as well as Nauru, which was placed under joint Australian-British-New Zealand jurisdiction. These mandates (and, later, United Nations trust territories) became the independent nations of Nauru and Papua New Guinea in the mid-20th century. Australia has also obtained several small island territories, mainly from earlier British colonies, and has a large claim on Antarctica.

Colonial period
| Date | Event | Map |
|---|---|---|
| 25 April 1787 | The Colony of New South Wales was created as a penal colony by the Kingdom of Great Britain in Australia east of 135° east.[1] Word of the establishment was proclaimed in Australia by Governor Arthur Phillip on 7 February 1788.[2] The commission included "all the islands adjacent in the Pacific Ocean" within the latitudes of 10°37' south and 43°39' south, which included most of New Zealand.[1] | Map of British claims to Australia; for details, refer to adjacent text |
| 11 July 1810 | Macquarie Island was discovered by Frederick Hasselborough, who claimed it for the United Kingdom and declared it part of New South Wales.[3][4] | Map of British claims to Australia; for details, refer to adjacent text |
| 16 July 1825 | New South Wales was extended west to 129° east, so that it would include a trading post set up on Melville Island; and the borders of the "islands adjacent in the Pacific Ocean" were moved north to 39°12' south, now including only a small part of New Zealand.[5] | Map of British claims to Australia; for details, refer to adjacent text |
| 3 December 1825 | The southern islands of New South Wales were made the Colony of Van Diemen's Land.[6][7] | Map of British claims to Australia; for details, refer to adjacent text |
| 2 May 1829 | A colony commonly known as the Swan River Colony was founded in the remainder of Australia outside of New South Wales.[8] Most documents calling for the colony's foundation make no mention of a name, apart from its location at the "Port on the Western Coast of New Holland, at the Mouth of the River called 'Swan River', with the adjacent Territory",[9] and that a settlement should be formed "within the Territory of 'Western Australia'".[10] However, the law calling for the creation of the colony does appear to specify that it should be called "Western Australia".[11] | Map of British claims to Australia; for details, refer to adjacent text |
| 6 February 1832 | The legal instrument required to formally appoint James Stirling governor of the Colony of Western Australia was proclaimed, and this is commonly held as the date that the Swan River Colony was renamed Western Australia.[12][13] | Map of British claims to Australia; for details, refer to adjacent text |
| 19 February 1836 | The portion of New South Wales between 132° east and 141° east, and south of 26° south, was made the Province of South Australia.[14] The actual landing and proclamation occurred on 28 December 1836.[15] Its border with New South Wales south of the Murray River would be erroneously surveyed roughly Script error: No such module "convert". west of 141° east, and the resulting disputes with the colonies and, later, states that share that border would not be fully resolved until 1914.[16] | Map of British claims to Australia; for details, refer to adjacent text |
| 15 June 1839 | The islands of New Zealand were annexed to New South Wales.[17][18] The action was proclaimed on 14 January 1840.[19] | Map of British claims to Australia; for details, refer to adjacent text |
| 16 November 1840 | The Colony of New Zealand was chartered and split from New South Wales.[20][21] | Map of British claims to Australia; for details, refer to adjacent text |
| 26 September 1844 | Norfolk Island was transferred from New South Wales to Van Diemen's Land.[22] | Map of British claims to Australia; for details, refer to adjacent text |
| 17 February 1846 | The half of New South Wales north of 26° south was made the Colony of North Australia.[23][24][25] | Map of British claims to Australia; for details, refer to adjacent text |
| 28 December 1847 | Following a change in government in the United Kingdom, North Australia was merged back in to New South Wales.[23][25] This is the date Queen Victoria revoked the letters patent establishing North Australia, but it was not proclaimed in Australia until 16 January 1849. | Map of British claims to Australia; for details, refer to adjacent text |
| 1 July 1851 | The portion of New South Wales south of the Murray River and a line from the headwaters of the river to Cape Howe was made the Colony of Victoria.[26] | Map of British claims to Australia; for details, refer to adjacent text |
| 1 January 1856 | Van Diemen's Land was renamed Tasmania, as a way to get away from its past as a penal colony.[27] | Map of British claims to Australia; for details, refer to adjacent text |
| 1 November 1856 | Norfolk Island was split from Tasmania, becoming its own colony.[28] Some sources say this occurred the previous day,[29] but the Norfolk Island Act 1913 states it was on this day. | Map of British claims to Australia; for details, refer to adjacent text |
| 6 June 1859 | The portion of New South Wales north of 29° south, the Dumaresq and Macintyre Rivers, and several mountain ridges, and east of 141° east, was made the Colony of Queensland.[30] | Map of British claims to Australia; for details, refer to adjacent text |
| 10 October 1861 | The portion of New South Wales west of South Australia was transferred to South Australia by letters patent. The act of parliament was passed on 22 July 1861.[31] | Map of British claims to Australia; for details, refer to adjacent text |
| 13 March 1862 | The portion of New South Wales north of South Australia and east of 138° east was transferred to Queensland.[32] | Map of British claims to Australia; for details, refer to adjacent text |
| 6 July 1863 | The region of New South Wales north of South Australia was transferred to South Australia.[33] | Map of British claims to Australia; for details, refer to adjacent text |
| 30 May 1872 | All islands lying within Script error: No such module "convert". of Queensland were annexed to the colony by letters patent.[34] This was done primarily to incorporate the Torres Strait Islands, which were starting to be claimed by New South Wales. It is unknown which specific islands may have already been considered part of Queensland, and the map included with the letters patent contained errors, such as including Melville Island in Queensland.[35] | too vague to map |
| 21 July 1879 | The Torres Strait Islands were specifically annexed to Queensland.[34][35] | Map of British claims to Australia; for details, refer to adjacent text |
| 17 June 1880 | Macquarie Island was made a constituent part of the Colony of Tasmania through Letters Patent for the Governor of Tasmania.[36] | Map of British claims to Australia; for details, refer to adjacent text |
| 4 April 1883 | Queensland claimed southeast New Guinea as a dependency, though the British government rejected the claim.[37] | Map of British claims to Australia; for details, refer to adjacent text |
| 6 November 1884 | The British Empire declared southeast New Guinea as a protectorate, removing it from immediate Queensland control, though the colony still largely administered it.[38] | Map of British claims to Australia; for details, refer to adjacent text |

Proposed boundary change to the Australian Capital Territory
In September 2022, it was announced the border between the Australian Capital Territory and New South Wales would change for the first time since it was created in 1911.[89] ACT chief minister Andrew Barr said NSW premier Dominic Perrottet had agreed to a proposed border change for 330 hectares of land.[90]
