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 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.[1] (The first woman candidates for the South Australia Assembly ran in 1918 general election, in Adelaide and Sturt.[2])

From 1857 to 1933, the House of Assembly was elected from multi-member districts, commonly known as "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, 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 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 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".[3]

Another distinctive aspect of the history of the South Australian Parliament was the "Playmander", a gerrymandering system that instituted a pro-rural electoral malapportionment introduced by the incumbent Liberal and Country League (LCL) government, and in place for 32 years from 1936 to 1968.[4] 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, the rural seat of Frome had 4,500 formal votes, while the metropolitan seat of Enfield had 42,000 formal votes.[5]
Labor won enough parliamentary seats to form government just once during the Playmander against the odds − in 1965. Labor won comprehensive majorities of the statewide two-party vote whilst failing to form government in 1944, 1953, 1962 and 1968.[5]
More equitable boundaries were subsequently put in place following the 1968, 1975, and 1989 elections.[5]
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.
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 election for example, although the state-wide 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.[6]
Donald Allan Dunstan was an Australian politician who served as the 35th premier of South Australia from 1967 to 1968, and again from 1970 to 1979. He was a member of the House of Assembly (MHA) for the division of Norwood from 1953 to 1979, and leader of the South Australian Branch of the Australian Labor Party from 1967 to 1979. Before becoming premier, Dunstan served as the 38th attorney-general of South Australia and the treasurer of South Australia. He is the fourth longest serving premier in South Australian history.
The Parliament of South Australia is the bicameral legislature of the Australian state of South Australia. It consists of the 47-seat House of Assembly and the 22-seat Legislative Council. General elections are held every 4 years, with all of the lower house and half of the upper house filled at each election. It follows a Westminster system of parliamentary government with the executive branch required to both sit in parliament and hold the confidence of the House of Assembly. The parliament is based at Parliament House on North Terrace in the state capital of Adelaide.
The Liberal Movement (LM) was a South Australian political party which existed from 1973 to 1976, and was a forerunner to the Australian Democrats.
The Bjelkemander was the term given to a system of malapportionment in the Australian state of Queensland in the 1970s and 1980s. Under the system, electorates were allocated to zones such as rural or metropolitan and electoral boundaries drawn so that rural electorates had about half as many voters each as metropolitan ones. The Country Party, a rural-based party led by Joh Bjelke-Petersen, was able to govern uninhibited during this period due to the 'Bjelkemander' and the absence of an upper house of Parliament.
Since 1970, the South Australian House of Assembly — the lower house of the Parliament of South Australia — has consisted of 47 single-member electoral districts consisting of approximately the same number of enrolled voters. The district boundaries are regulated by the State Electoral Office, according to the requirements of the South Australian Constitution and are subject to mandatory redistributions by the South Australian Electoral Districts Boundaries Commission in order to respond to changing demographics.
