Elections

In South Australia, whole of state council elections (called periodic elections) are held every 4 years for all 68 councils except the Municipal Council of Roxby Downs, which operates under its own administration.

If an elected position on a council becomes vacant between periodic elections, ECSA may conduct a supplementary election (often described as a by-election). A vacancy can occur due to death, illness, resignation, or any other circumstances according to the Local Government (Elections) Act 1999.

Responsibilities as a member of a council

Councils are responsible for many of the services that make South Australia such a great place to live and work, including libraries, playgrounds, sporting facilities and rubbish and recycling.

Becoming a councillor or mayor means you will help shape a wide range of policies and decisions that will impact the short and long-term future of your local community.

More information can be found on the council elections website.

By-elections

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.
