Essential information about the Northern Territory redistribution

Updated: 2 February 2016

Why is the Northern Territory undergoing a redistribution?

The Northern Territory is undergoing a redistribution because more than seven years have elapsed since the last redistribution.

Sub-section 59(2) of the Commonwealth Electoral Act 1918 (the Electoral Act) specifies 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.

The most recent redistribution of the Northern Territory was determined on 19 September 2008. A redistribution was therefore required to commence within 30 days of 19 September 2015.

The redistribution formally commenced on 15 October 2015.

Will the boundaries of the electoral divisions change?

The boundaries of the electoral divisions will definitely change. There are two numerical ranges the Electoral Act specifies for electoral divisions:

  • as far as practicable, the number of electors enrolled in each electoral division in the Northern Territory at the projection time would not be more than plus or minus 3.5 per cent of the projected enrolment quota (paragraph 73(4)(a) of the Electoral Act)
    • As far as practicable, the number of electors enrolled in each electoral division in the Northern Territory at the projection time of 7 August 2020 must be between 68 214 and 73 162.
  • the number of electors enrolled in each electoral division in the Northern Territory would not be more than plus or minus 10 per cent of the current enrolment quota (sub-section 73(4) of the Electoral Act)
    • The number of electors enrolled in each electoral division in the Northern Territory must be between 58 308 and 71 264.

On the boundaries in place when the redistribution started on 15 October 2015, the number of electors enrolled in both the Divisions of Lingiari and Solomon meet the requirement to be not more than plus or minus 10 per cent of the current enrolment quota (see Figure 1). However, neither electoral division meets the requirement to be not more than plus or minus 3.5 per cent of the projected enrolment quota at the projection time, (see Figure 2) as:

  • the Division of Lingiari is less than the permissible minimum number of projected electors at the projection time of 7 August 2020, and
  • the Division of Solomon is more than the permissible maximum number of projected electors at the projection time of 7 August 2020.

As a consequence, the Redistribution Committee will be required to adjust the boundaries of both current electoral divisions so that the requirements of the Electoral Act can be met.

Will the names of the electoral divisions change?

The names of the electoral divisions may or may not change.

Individuals and organisations are able to propose alternative names for electoral divisions at two stages of the redistribution process:

  • the suggestions and comments on suggestions stage, and
  • the objections and comments on objections stage.

The Redistribution Committee will consider any ideas it receives in suggestions and comments on suggestions advocating a change of name for an electoral division and in their proposed redistribution will indicate whether it has or has not proposed changing the name of an electoral division, together with reasons for the proposal.

Individuals and organisations can object to the Redistribution Committee's proposed names of electoral divisions. Any ideas received in objections and comments on objections advocating a change of name for an electoral division will be considered by the augmented Electoral Commission for the Northern Territory, who is ultimately responsible for determining the names of the electoral divisions in the Northern Territory.

Why are Christmas Island and Cocos (Keeling) Island included in this redistribution?

Under section 56A of the Electoral Act, until such time as the Territory of the Christmas Islands or the Territory of Cocos (Keeling) Island is entitled to a member of the House of Representatives, each Territory is to be included in an electoral division in the Northern Territory.

As part of a determination on 13 November 2014 of the number of members of the House of Representatives to which each state and territory will be entitled at the next federal general election, it was determined that:

  • the Territory of Christmas Island was not entitled to a member of the House of Representatives, and
  • the Territory of Cocos (Keeling) Island was not entitled to a member of the House of Representatives.

Christmas Island and Cocos (Keeling) Island will therefore need to be located in the same electoral division in the Northern Territory.

When the redistribution commenced on 15 October 2015, Christmas Island and Cocos (Keeling) Island were located in the Division of Lingiari.

Will the redistribution be implemented before the 2016 federal election?

Changes to electoral divisions as a result of this redistribution will apply from the day on which a notice of determination is published in the Commonwealth Notices Government Gazette. This notice will be published on 7 February 2017.

The electoral divisions which will apply at the 2016 federal election will therefore be the same as those which applied at the 2013 federal election.
