Redistributions

The NT covers approximately 1,620,000 square kilometres and has 25 Legislative Assembly divisions; each represented by one elected Member of the Legislative Assembly. Electoral divisions are very different in geographical size and can range from as little as four square kilometres to almost 450,000 square kilometres. However, each division has approximately the same number of electors, around 5,000.

Electoral divisions may also be know as constituencies, electorates or seats - the term electorate can also refer to the electors enrolled in that division.

What is a redistribution?

In accordance with Part 8, division 2, s138(2) of the Electoral Act, the redistribution process must start and finish as soon as practicable two years and six months after election day for the previous general election. The boundaries of each division are reviewed and changed, if necessary, so that the number of electors in each division are as near to equal as practicable. Any changes become effective at the next general election.

The redistribution process is managed by the Redistribution Committee and consists of the following members:

  • the Electoral Commissioner
  • the Surveyor-General
  • the Auditor-General
  • the appointed member (a person who has served as, or is qualified for appointment as, a Supreme Court Judge or Local Court Judge, is not a member of a political party and does not have a recent political affiliation).

NOTE: The appointed member is the Chairperson of the Redistribution Committee.

This committee:

  • calls for public suggestions
  • publishes those suggestions and invites comments on those suggestions
  • publishes a first proposed redistribution after considering suggestions and comments received
  • calls for objections to the first proposed redistribution
  • prepares the second redistribution and invites objections
  • considers objections, decides redistribution and prepares a redistribution report.

The redistribution is carried out in accordance with the Electoral Act and the Northern Territory (Self-Government) Act. It is an impartial and transparent process, free of political interference and provides several opportunities for public participation; any individual or organisation has the opportunity to present suggestions, comments or objections to the committee.

When is the next redistribution?

The next redistribution of NT Legislative Assembly electoral boundaries is in 2019. A notice, inviting public suggestions, will be placed in the Gazette and Territory newspapers on 26 February 2019. Suggestions are to be given to the committee, in writing, within 30 days after the notice is published.

History of redistributions in the NT

A partly elected, partly nominated Legislative Council was established for the governance of the Northern Territory between 1947 and 1974. Five redistributions were carried out – the first in 1947 for six elected members, the second in 1959 when the number of elected members was increased to eight, 1962 when Aboriginals were given the vote, 1965 and lastly in 1968 when elected members increased to eleven.

The first distribution into 19 electoral divisions for a wholly elected legislature for the Northern Territory was established by the Minister for the Territory in early 1974 and reported in September 1974. A redistribution in 1977 took account of population movements following Cyclone Tracy.

Following self-government in 1978, electoral terms were extended from three to a maximum of four years. Set-term elections every four years became effective in 2012.

Early distributions were carried out by a three person Distribution Committee, comprising the Chief Electoral Officer, the Surveyor-General and a person appointed by the Administrator. Suggestions were submitted to the committee which released a proposed map, received objections and forwarded a report to the Minister for tabling in, and the approval of, the legislature.

The following table indicates all electoral boundary deliberations for a wholly elected Northern Territory Legislative Assembly since 1974.

Object, principles and matters to be considered in redistribution

The Redistribution Committee is constituted under and operates in accordance with the Electoral Act and the Northern Territory (Self-Government) Act.

Object of redistribution

The object of a redistribution is to ensure that, at the time of the next general election, the number of electors in each proposed division is as near to equal as practicable.

Principles of redistribution

To satisfy the object of redistribution, the Redistribution Committee must have regard to the following principles:

    (a) the physical area of a division containing rural and remote areas should be as small as practicable

    (b) the demographic characteristics of a division should be as uniform as practicable

    (c) the geographic features of a division should be as uniform as practicable

    (d) each identifiable community should be included in only one division if practicable

    (e) subject to paragraphs (a) to (d), changes to existing division should minimise the number of electors being transferred from one division to another.

Naming of division during redistribution:

    (1) The name of a division must not be changed by a redistribution unless the existing name is no longer appropriate.

    (2) If a new name is proposed for a division, the use of locality names should be avoided.

Matters to be considered in redistribution

The committee must consider the following matters as set out in section 140 of the Electoral Act in achieving the object of a redistribution:

    (1) The number of electors in each proposed division meets the requirement of section 13(4) of the Northern Territory (Self Government) Act relating to divergence from one-fifth of a quota.

    (2) In addition, the Redistribution Committee must give proper consideration to the following matters:

    • (a) community of interests in each proposed division, including economic, social and regional interests
    • (b) types of communication and travel in each proposed division, with special reference to disabilities arising out of remoteness or distance
    • (c) the trend of population changes in the Territory
    • (e) the area of each proposed division
    • (f) the physical features of each proposed division
    • (g) the existing boundaries of the following:
    • (h) all suggestions and comments.

Preparing second proposed redistribution : After giving proper consideration to all objections, the Redistribution Committee, as soon as practicable after the 30 days, must prepare the second proposed redistribution of the Territory into divisions. The second proposed redistribution must include proposed names for the proposed divisions. Electoral Act s145A
Inviting objections to second proposed redistribution : If the second proposed redistribution would result in the following, the Redistribution Committee must invite objections to the second proposed redistribution.
  • if a second proposed redistribution would result in the sum of the number of electors either added to or removed from a division being greater than 15% of the total number of electors in a division at the time the quota is calculated.
  • if, in the opinion of the Redistribution Committee, a second proposed redistribution involves significant change in a matter to which the committee must give consideration (see matters to be considered in redistribution - Electoral Act s140(2)(a), (c), (e), (f) or (g))

If the Redistribution Committee invites objections to a second proposed redistribution the committee must make available for public inspection maps showing the names and boundaries of all proposed divisions and publish a notice in the Gazette and Territory newspapers inviting objections to the second proposed redistribution.

Despite the above, the Redistribution Committee is not required to invite objections to the second proposed redistribution if the committee is of the opinion that:

  • holding a second objection period would cause major inconvenience or have other serious consequences, such as causing a delay to a scheduled general election
  • the second proposed redistribution is the only feasible option because there has been a natural disaster or another event causing extraordinary demographic movement. (Electoral Act s145B(2)(a), (b))
