When is the next redistribution of my state or territory due?

Updated: 13 July 2020

The Commonwealth Electoral Act 1918 (the Electoral Act) requires that a redistribution process should be undertaken when:

  • the number of members of the House of Representatives to which a state or territory is entitled has changed,
  • the number of electors in more than one-third of the electoral divisions in a state (or one of the electoral divisions in the Australian Capital Territory or the Northern Territory) deviates from the average divisional enrolment by over ten per cent for a period of more than two months, or
  • a period of seven years has elapsed since the last redistribution process was determined.

Indicative timing

Unless a redistribution is required to start earlier or is deferred, the next redistribution will be due to commence within 30 days after seven years have elapsed since the most recent redistribution was determined.
