A state election will be held on 16 March 2030 to elect the members of the 57th Parliament of South Australia. All 47 seats in the House of Assembly (lower house) will be up for election, along with 11 of the 22 seats in the Legislative Council (upper house).

The incumbent Labor government, led by Premier Peter Malinauskas, is expected to seek a third four-year term in government. It is expected that they will be challenged by the Liberal Party, led by Opposition Leader Ashton Hurn, and One Nation, led by Cory Bernardi. It is expected that the Greens and other minor parties and independents will contest the election.

South Australia has compulsory voting, with full-preference instant-runoff voting for single-member electorates in the lower house, and optional preference single transferable voting in the proportionally represented upper house. The election will be conducted by the Electoral Commission of South Australia (ECSA), an independent body answerable to Parliament, and will be held on the same day as the South Australian First Nations Voice election.

Background Previous election

At the previous election in March 2026, the Labor Party, led by Peter Malinauskas, was returned to government for a second four-year term, winning 34 seats in the House of Assembly, enough for a ten-seat majority. The Liberal Party, won only 5 seats and formed the official opposition. The crossbench consisted of four members of One Nation, and four independents: Geoff Brock, Matt Schultz, Travis Fatchen, and Lou Nicholson.

In the Legislative Council, Labor gained a tenth seat, remaining the largest party in the upper house. Following the election, Labor MLC Reggie Martin was elected to the chamber's presidency, meaning that Labor required two additional votes to pass legislation. The Liberals were reduced to six seats, and the Greens remained steady at two. One Nation won three seats, and Connie Bonaros, the last remaining SA Best MP, was defeated.

Composition of Parliament

In May 2026, at the first sitting of the newly-elected Parliament, Labor MP Nat Cook was elected as Speaker of the House of Assembly and temporarily left the Labor Party, as is required for the role of Speaker. In June 2026, Sarah Game defected from her own party to join Family First, on the same night that her Bill proposing new limits on late term abortions was being debated in Parliament.

Electoral system Members of the House of Assembly are elected by instant-runoff voting using full preferential voting. Each electoral district elects a single member.

Members of the Legislative Council are elected by proportional representation using a single transferable vote. Members serve staggered eight-year terms with half of the Council elected at each state election.

Upcoming redistribution As required under the South Australian Constitution, the South Australian Electoral Districts Boundaries Commission must re-draw the boundaries of the House of Assembly electoral districts after each election.

Election date The last state election was held on 21 March 2026 to elect members for the House of Assembly and half of the members in the Legislative Council. In South Australia, section 28 of the Constitution Act 1934, as amended in 2001, directs that parliaments have fixed four-year terms, and elections must be held on the third Saturday in March every four years unless this date falls the day after Good Friday, occurs within the same month as a federal election, or the conduct of the election could be adversely affected by a state disaster. Section 28 also states that the Governor may also dissolve the Assembly and call an election for an earlier date if the government has lost the confidence of the Assembly or a bill of special importance has been rejected by the Legislative Council. Section 41 states that both the Council and the Assembly may also be dissolved simultaneously if a deadlock occurs between them.

The Electoral (Miscellaneous) Amendment Act 2013 introduced set dates for writs for general elections in South Australia. The writ sets the dates for the close of the electoral roll and the close of nominations for an election. The Electoral Act 1985 requires that, for a general election, the writ be issued 28 days before the date fixed for polling (S47(2a)) and the electoral roll be closed at 12 noon, six days after the issue of the writ (S48(3(a)(i))). The close of nominations will be at 12 noon three days after the close of rolls (Electoral Act 1985 S48(4)(a) and S4(1)). Issue of writ Contents of writ Interpretation
