2026 South Australian state election

The 2026 South Australian state election will be held on 21 March 2026 to elect the 56th Parliament of South Australia. All 47 seats in the House of Assembly will be up for election, along with 11 of the 22 seats in the Legislative Council.

The incumbent Labor government, led by Premier Peter Malinauskas, will seek a second four-year term in government. They will be challenged by the Liberal Party, led by Opposition Leader Ashton Hurn. In addition to the two major parties, the Greens and One Nation will be contesting every lower house electorate. Several other minor parties and independents will also contest the election in both houses. This election will see 436 candidates across both houses, the most in the state's history.

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.
