Election Day 17 March

The 2018 South Australian state election will elect members to the 54th Parliament of South Australia on 17 March 2018.

All 47 seats in the House of Assembly or lower house, whose current members were elected at the 2014 election, and 11 of 22 seats in the Legislative Council or upper house, last filled at the 2010 election, are now vacant.

The record-16-year-incumbent Australian Labor Party (SA) government, currently led by Premier Jay Weatherill, will seek a fifth four-year term against the opposition Liberal Party of Australia (SA), currently led by Opposition Leader Steven Marshall.

Also aspiring to win seats in the lower house, is Nick Xenophon's new SA Best party.
