Enrolment and voting are related but separate
The Commonwealth electoral system uses an electoral roll to determine who is enrolled and which electorate they vote in. Eligible Australian citizens are generally required to enrol and keep their enrolment details current. The AEC maintains the federal roll and provides tools for checking and updating enrolment.
Compulsory voting operates once an election is held. It is therefore useful to distinguish the ongoing duty to maintain enrolment from the election-time obligation to vote.
Why address details matter
House of Representatives elections are based on geographic divisions, so a voter's enrolled address determines which House contest they participate in. The address also affects state or territory representation and the electoral information sent to the voter.
A change of address can therefore change the electorate in which a person is enrolled. During an election period, statutory roll-close deadlines can affect how late changes are processed, so current AEC guidance matters.
What compulsory voting means
At federal elections and referendums, enrolled electors are generally required to vote. The AEC administers non-voter processes after an election and can contact people whose names were not marked as having voted. There are statutory procedures for responding to those notices.
Compulsory voting does not mean an elector is required to support a particular candidate or party. The secrecy of the ballot protects the political choice made by the voter.
The electoral roll and integrity
An accurate electoral roll supports both participation and election integrity. The AEC uses enrolment processes, data matching and other lawful administrative mechanisms to maintain the roll. Political parties and candidates may receive access to electoral-roll information under rules set by law.
Claims about the roll should be checked against the AEC and electoral legislation rather than campaign rhetoric. The rules governing enrolment, access and objections are detailed and can change through legislation.
Where to check your position
People can use the AEC's official enrolment services to check whether they are enrolled and update details. During an election, the AEC also publishes key dates, enrolment deadlines and voting options.
This page is general information only. If a person has received a non-voter notice or needs advice about a specific legal obligation, the AEC or an appropriately qualified adviser should be consulted.
