The '''House of Assembly''' is the [[lower house]] of the [[bicameralism|bicameral]] [[Parliament of South Australia]], the [[upper house]] being the [[South Australian Legislative Council|Legislative Council]].

==Overview==
The House of Assembly was created in 1857, when South Australia attained self-government. The development of an elected legislature — although only men could vote — marked a significant change from the prior system, where legislative power was in the hands of the Governor and the Legislative Council, which was appointed by the Governor.

In 1895, the House of Assembly [[Constitutional Amendment (Adult Suffrage) Act 1894|granted women the right to vote and stand for election]] to the legislature. South Australia was the second place in the world to do so after [[New Zealand]] in 1893, and the first to allow women to stand for election.<ref>{{Cite web |url=https://www.parliament.sa.gov.au/education/teachers/Documents/Women's%20Petition%20Photograph.pdf |title=Women's Suffrage Petition 1894: parliament.sa.gov.au |access-date=8 January 2016 |archive-date=29 March 2011 |archive-url=https://web.archive.org/web/20110329160732/http://www.parliament.sa.gov.au/education/teachers/Documents/Women%27s%20Petition%20Photograph.pdf |url-status=dead}}</ref> (The first woman candidates for the South Australia Assembly ran in 1918 general election, in Adelaide and Sturt.<ref>History of South Australia Elections, House of Assembly, volume 1</ref>)

[[File:'South Australian Parliament; the House of Assembly', c. 1867.jpg|thumb|A painting of the House of Assembly meeting in Old Parliament House in 1867]]
From 1857 to 1933, the House of Assembly was elected from multi-member districts, commonly known as "[[South Australian Electoral Districts|seats]]", with each district returning between one and six members. The size of the Assembly varied during this time—36 members from 1857 to 1875, 46 members from 1875 to 1884, 52 members from 1884 to 1890, 54 members from 1890 to 1902, 42 members from 1902 to 1912, 40 members from 1912 to 1915 after the [[Northern Territory]] was ceded to federal administration, and 46 members from 1915 to 1938. In 1938, the Assembly was reduced to 39 members, elected from single-member districts.

The House of Assembly has had 47 members since the [[1970 South Australian state election|1970 election]], elected from single-member districts: currently 34 in the [[Adelaide]] metropolitan area and 13 in rural areas. These seats are intended to represent approximately the same population in each electorate. Voting is by [[Instant-runoff voting]] and [[preferential voting]] with complete preference allocation, as with the equivalent federal chamber, the [[Australian House of Representatives]]. All members face re-election approximately every four years. The most [[2022 South Australian state election|recent election]] was held on 19 March 2022.

The House is presided over by a Speaker, who, as of the passage of the ''Constitution (Independent Speaker) Amendment Act 2021'', is constitutionally banned from being a member of a registered political party outside of a "relevant election period".<ref>Constitution (Independent Speaker) Amendment Act 2021</ref>

[[File:Playmander Map.svg|thumb|A map of South Australian electorates 1955-69, during the height of the Playmander]]
Another distinctive aspect of the history of the South Australian Parliament was the "[[Playmander]]", a [[gerrymander|gerrymandering system]] that instituted a pro-rural electoral [[Apportionment (politics)|malapportionment]] introduced by the incumbent [[Liberal and Country League]] (LCL) government, and in place for 32 years from 1936 to 1968.<ref>[https://archive.today/20120709065419/http://www.history.sa.gov.au/history/Democracy%20Conference/JaenschPARTIES.pdf Labor and Liberal Parties, SA, Dean Jaensch] {{Webarchive|url=https://web.archive.org/web/20221206011920/https://archive.ph/2012.07.09-065419/http://www.history.sa.gov.au/history/Democracy%20Conference/JaenschPARTIES.pdf |date=6 December 2022 }}, "A 2:1 ratio of enrolments in favour of the rural areas was in force from 1936."</ref> The already entrenched rural overweighting was increased to a 2:1 ratio, the number of MPs was reduced to 39 and the multi-member seats were abandoned for single-member seats. The House of Assembly now consisted of 26 low-population rural seats, which due to population shifts, were holding up to a 10-to-1 advantage over the 13 high-population metropolitan seats, even though rural seats contained only a third of South Australia's population. At the peak of the malapportionment in [[1968 South Australian state election|1968]], the rural seat of [[Electoral district of Frome|Frome]] had 4,500 formal votes, while the metropolitan seat of [[Electoral district of Enfield|Enfield]] had 42,000 formal votes.<ref name="access">{{cite news |last=Jaensch |first=Dean |title=Community access to the electoral processes in South Australia since 1850 |year=2002 |publisher=South Australian State Electoral Office |url=http://www.ecsa.sa.gov.au/publications?view=document&id=479 |archive-url=https://web.archive.org/web/20160308203426/http://www.ecsa.sa.gov.au/publications?view=document&id=479 |archive-date=8 March 2016}}</ref>

[[Australian Labor Party (South Australian Branch)|Labor]] won enough parliamentary seats to form government just once during the Playmander against the odds − in [[1965 South Australian state election|1965]]. Labor won comprehensive majorities of the statewide [[Two-party-preferred vote|two-party]] vote whilst failing to form government in [[1944 South Australian state election|1944]], [[1953 South Australian state election|1953]], [[1962 South Australian state election|1962]] and [[1968 South Australian state election|1968]].<ref name="access" />

More equitable boundaries were subsequently put in place following the [[1968 South Australian state election|1968]], [[1975 South Australian state election|1975]], and [[1989 South Australian state election|1989]] elections.<ref name="access" />

Most legislation is initiated in the House of Assembly. The party or coalition with a majority of seats in the lower house is invited by the Governor to form government. The leader of that party becomes [[Premier of South Australia]], and their senior colleagues become ministers responsible for various portfolios. As Australian MPs almost always vote along party lines, almost all legislation introduced by the governing party will pass through the House of Assembly.

[[File:South Australian House of Assembly Ballot Paper.png|thumb|150px|South Australian House of Assembly ballot paper]]
As with the federal parliament and Australian other states and territories, voting in the Assembly is compulsory for all those over the age of 18. Voting in the House of Assembly had originally been voluntary, but this was changed in 1942.

While [[South Australia]]'s total population is 1.7 million, 1.3 million of them live in Adelaide. Over 75% of the state's population resides in the metropolitan area. As a result, Adelaide accounts for 72% (34 of 47) of the seats in the chamber. The dominance of Adelaide, combined with a lack of comparatively-sized rural population centres, results in the metropolitan area frequently deciding election outcomes. At the [[2014 South Australian state election|2014 election]] for example, although the state-wide [[Two-party-preferred vote|two-party vote]] (2PP) was 47.0% Labor v 53.0% Liberal, the metropolitan area recorded a 2PP of 51.5% Labor v 48.5% Liberal.<ref>Metropolitan 2PP correctly calculated by adding raw metro 2PP vote numbers from the 34 metro seats, both Labor and Liberal, then dividing Labor's raw metro 2PP vote from the total, which revealed a Labor metropolitan 2PP of 51.54%. Obtained raw metro 2PP vote numbers from ECSA [http://www.ecsa.sa.gov.au/publications?view=document&id=1006 2014 election statistics] {{Webarchive|url=https://web.archive.org/web/20160307214109/http://www.ecsa.sa.gov.au/publications?view=document&id=1006 |date=7 March 2016 }}, ECSA [http://www.ecsa.sa.gov.au/elections/state-elections/past-state-election-results/7678?view=result 2014 Heysen election] {{Webarchive|url=https://web.archive.org/web/20141211062918/http://www.ecsa.sa.gov.au/elections/state-elections/past-state-election-results/7678?view=result |date=11 December 2014 }} and ABC [http://www.abc.net.au/elections/sa/2014/fisher/ 2014 Fisher by-election] {{Webarchive|url=https://web.archive.org/web/20201114231927/http://www.abc.net.au/elections/sa/2014/fisher/ |date=14 November 2020 }}.</ref>
