Elections in Australia

Elections in Australia take place periodically to elect the legislature of the Commonwealth of Australia, as well as for each Australian state and territory and for local government councils. Elections in all jurisdictions follow similar principles, although there are minor variations between them. The elections for the Australian Parliament are held under the federal electoral system, which is uniform throughout the country, and the elections for state and territory Parliaments are held under the electoral system of each state and territory.

Part IV of Chapter 1 of the Australian Constitution briefly deals with eligibility for voting and election to the federal Australian Parliament. It does not prescribe how elections should be conducted. Election campaigns and associated political advertisements are subject to some regulation. Public funding of political parties and party registration was introduced in 1983.

Voting for the federal and each state and territory parliament is compulsory for Australian citizens over the age of 18. Voting is almost entirely conducted using paper ballots. The informal vote is not usually significant, but a donkey vote is more common, and may have a deciding impact in marginal seats.
