form. If a change of address causes an individual to move to another electorate (electoral division), they are legally obliged to notify the AEC within 8 weeks. The AEC monitors house and apartment sales and sends a reminder (and the forms) to new residents if they have moved to another electorate, making compliance with the law easier. The AEC conducts periodic door-to-door and postal campaigns to try to ensure that all eligible persons are registered in the correct electorate. An individual has 8 weeks after turning 18 to register and the 8-week period also applies to update of details. Failure to enrol or update details can incur a fine.
