Like federal elections, South Australia has compulsory voting, uses 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.
Date
The last state election was held on 19 March 2022 to elect members for the House of Assembly and half of the members in the Legislative Council.[1]
Section 28 of the Constitution Act 1934, as amended in 2001, states that parliaments have fixed four-year terms, with elections to 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.[2]
