The redistribution of federal electoral boundaries in South Australia commenced on 12 January 2011. South Australia is entitled to 11 members in the House of Representatives.
The Commonwealth Electoral Act 1918 (the Electoral Act) provides that the Electoral Commission shall commence a redistribution if a period of seven years has elapsed since the state was last distributed into Electoral Divisions (paragraph 59(2)). The Electoral Act also provides that the redistribution must be commenced within 30 days after the expiration of that seven year period. The last redistribution of South Australia was determined on 17 December 2003.
The Electoral Commission has also decided that the enrolment projection time for the purpose of the redistribution will be 21 January 2015.
The indicative timetable for the conduct of the redistribution is available. The redistribution is expected to be finalised (determined) on 16 December 2011.
Further details about the South Australian redistribution will be posted on the AEC website progressively throughout the year.
Members of the public will be invited to contribute suggestions about the redistribution during April and May. A further period of consultation will begin in August, after the proposed redistribution is announced.
General information about redistributions can be viewed at the redistribution FAQ.
The enrolment of new electors and changes to existing enrolments are implemented immediately following the redistribution determination of new boundaries. However, for the purpose of electing members of Parliament, the new boundaries do not come into effect until the next federal election.
If a by-election is held prior to the next federal election, the by-election will be conducted on existing boundaries.
If the writs for a federal election are issued before the completion of the South Australian redistribution, the election will be contested on the current boundaries. The redistribution process would continue irrespective of the election.
