Elections in Australia are the processes by which representatives to the Parliament of Australia, state and territory legislatures, and local councils are chosen. They involve the interaction of institutions such as the Australian Electoral Commission, political organisations like the Australian Labor Party and the Liberal Party of Australia, and judicial oversight from courts including the High Court of Australia and state supreme courts. The practices reflect a mix of British-derived parliamentary traditions, innovations such as preferential ballots, and Indigenous enfranchisement struggles tied to instruments like the Commonwealth Electoral Act 1918.
Australian federal elections use a combination of electoral mechanisms: preferential voting (instant-runoff voting) in single-member districts for the House of Representatives and a proportional system based on the single transferable vote for the Senate. The Commonwealth Electoral Act 1918 and subsequent amendments govern redistributions administered by the Australian Electoral Commission. Redistributions reference criteria from cases such as Roach v Electoral Commissioner and procedures mirrored in state redistribution authorities like the Western Australian Electoral Commission. Ballot design and above/below the line voting follow precedents from controversies seen in other jurisdictions like the Tasmanian Legislative Council elections and reforms after the 1998 Australian federal election Senate ticket issues.
Federal elections determine membership of the Parliament of Australia and the selection of the Prime Minister of Australia through confidence in the House of Representatives. Key moments include the double dissolutions provided under section 57 of the Constitution of Australia, such as the 1975 Australian constitutional crisis and the 2016 double dissolution. Federal contests feature major parties like the Australian Greens, the National Party of Australia, and minor and micro-parties including One Nation and the Liberal Democratic Party. Campaigns are shaped by media institutions like the Australian Broadcasting Corporation and commercial networks implicated during elections including in events resembling the 1993 Australian federal election and the 2019 Australian federal election.
States and territories operate distinct systems: the New South Wales Electoral Commission administers elections for the New South Wales Legislative Assembly using optional preferential voting, while the Victorian Electoral Commission and the Electoral Commission of Queensland implement local variants. The Northern Territory Legislative Assembly and the Australian Capital Territory Legislative Assembly have adopted forms of proportional representation and the Hare-Clark electoral system used in Tasmania and the Australian Capital Territory. Historical episodes such as the Playmander in South Australia and reforms following the Wright-Patman-style inquiries have produced redistribution rules comparable to federal practice.
Local government elections are managed by state and territory electoral bodies such as the Electoral Commission of Queensland and involve councils like City of Sydney, Brisbane City Council, and Melbourne City Council. Indigenous enfranchisement evolved through cases and legislation including the Commonwealth Franchise Act 1902 and later reforms influenced by advocacy groups such as the Aboriginal and Torres Strait Islander Commission and campaigns linked to figures like Eddie Mabo. Mechanisms for Indigenous representation include reserved positions in some jurisdictions and discussions around treaties like those pursued in Victoria and the Northern Territory; issues intersect with land rights instruments such as the Native Title Act 1993.
Major parties—the Australian Labor Party, Liberal Party of Australia, and the National Party of Australia—compete with minor parties and independents such as the Australian Greens and Centre Alliance. Campaign finance is regulated in part by the Commonwealth Electoral Act 1918 and overseen by the Australian Electoral Commission alongside scrutiny from bodies like the Australian Electoral Officers’ Council. Campaign tactics include preference deals exemplified during the 1990s in Australian politics and digital strategies scrutinised in inquiries similar to international probes into Cambridge Analytica-style activities. Political advertising, postal voting controversies, and preselection battles often involve trade unions such as the Australian Council of Trade Unions and business groups like the Business Council of Australia.
The Australian Electoral Commission administers federal elections, referendums, and redistribution processes; state equivalents include the Victorian Electoral Commission and the Electoral Commission of Queensland. Judicial review may be sought in the High Court of Australia and state supreme courts for disputes such as those arising under the Constitution of Australia and statutory provisions. Integrity frameworks involve bodies like the Commonwealth Ombudsman and laws including the Commonwealth Electoral Act 1918 and state electoral acts; historical reforms responded to events akin to the 1949 Australian federal election and scandals prompting regulatory change.
Voting is compulsory for Australian citizens aged 18 and over, a policy originating from early 20th-century reforms and legal affirmation in cases like Roach v Electoral Commissioner. Disenfranchisement issues historically affected groups including Indigenous Australians, women prior to reforms following the Commonwealth Franchise Act 1902, and residents of territories addressed in decisions such as Attorney-General (Cth); Ex parte McKinlay-style litigation. Eligibility and enrolment are regulated by the Australian Electoral Commission under the Commonwealth Electoral Act 1918, with penalties for non-voting and provisions for absentee and postal voting used in circumstances like the COVID-19 pandemic in Australia.
