Commonwealth Electoral Act 1918
The Commonwealth Electoral Act 1918 is the principal legislation governing federal elections in Australia. It establishes the framework for the enrolment of voters, the conduct of elections, the registration of political parties, the regulation of election funding and disclosure, and the administration of the Australian Electoral Commission (AEC). The Act provides for compulsory voting (introduced in 1924), preferential voting for the House of Representatives, and proportional representation by single transferable vote for the Senate. The Act has been amended numerous times, including to extend the franchise to Indigenous Australians (1962), to lower the voting age to 18 (1973), and to introduce public funding of election campaigns (1984).
Legal area: Constitutional and governance law establishes the framework of government, electoral processes, and the rule of law, including the separation of powers and federal-state relations.

Significance
The Commonwealth Electoral Act 1918 is fundamental to Australian democracy. Compulsory voting, one of Australia’s distinctive electoral features, produces turnout rates above 90%. The Act’s preferential voting system encourages coalition-building and preference negotiation. The independent Australian Electoral Commission, established under the Act, is widely respected for its integrity. The Act has been the subject of significant litigation, including challenges to the exclusion of prisoners from voting (Roach v Electoral Commissioner, 2007) and the conduct of electoral redistributions.
