Elected Premier

Lionel Hill
Labor

Each district elected multiple members. This election saw the change from first past the post (plurality) to instant-runoff (preferential) voting, which also meant that electors cast a single vote rather than multiple votes. With 30 of 46 seats in the House of Assembly, the election remains South Australian Labor's biggest seat win.
