The last entitlement determination was made on 29 September 2011. A total of 150 seats will be contested at the next federal election for the House of Representatives in accordance with the following table.
|New South Wales||48 seats|
|Western Australia||15 seats|
|South Australia||11 seats|
|Australian Capital Territory||2 seats|
|Northern Territory||2 seats|
The determination is published within 13 months after the first sitting of the next House of Representatives.
A separate Redistribution Committee is established for each State or Territory in which a redistribution has commenced. The Commonwealth Electoral Act requires that each Redistribution Committee must consist of the following people:
Each Committee has the task of producing a proposed set of boundaries and names for electoral divisions for the House of Representatives in that particular State or Territory.
A Redistribution Committee must develop a set of proposals for dividing each state or territory into a number of divisions equal to its entitlement in the House of Representatives. In developing its proposals, the Committee must remain within the numerical quotas for current and projected enrolment. The Committee also shall give due consideration to:
Boundaries are drawn so that, as far as practicable, three and a half years after the redistribution has been completed, the enrolment in each electoral division should not vary from the State average by more than 3.5%. Note that the Electoral Act provides separate provisions for the projection time if another redistribution is expected sooner than seven years.
The augmented Electoral Commission for the state or territory considers any objections and makes the final determination. The final report of the augmented Electoral Commission is tabled in the parliament.
Electors affected by changes to divisional boundaries will be notified of this change before the next federal election.
The enrolment of new electors and changes to existing enrolments are implemented immediately following the 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.
Note: If a by-election is held prior to the next federal election, the by-election will be conducted on existing boundaries not the redistributed boundaries.
If the writ for an election was issued before the completion of a redistribution and there was no change to the number of electoral divisions for the state or territory, the election would be contested on the old boundaries. The work of the Redistribution Committee would continue irrespective of the election.
If the writ for an election was issued before the completion of a redistribution which was occurring due to a change of entitlement, a mini-redistribution would be held (The Electoral Act s.76). A mini-redistribution takes place as follows:
