State elections

South Australian state elections are held on the 3rd Saturday in March every 4 years.

The next state election will be held on Saturday 19 March 2022. Voting is compulsory.

To find out more about enrolling, nominating and voting visit 2022 State Election.


A by-election is held when a seat in the House of Assembly of the South Australian Parliament becomes vacant. A by-election can occur at any time, so it is important to keep your name and address up to date on the electoral roll.

If a by-election is held in the electoral district in which you are enrolled, it is compulsory to vote.
