Redistribution of Western Australia into electoral divisions

Updated: 8 February 2016

Chapter 1 - Background and context

This chapter outlines the legislative requirements of the redistribution from the release of the Redistribution Committee’s proposed redistribution to the determination of the names and boundaries of electoral divisions by the augmented Electoral Commission.

  1. A redistribution of electoral divisions is the process where electoral divisions and their boundaries and names are reviewed, and may be altered, to ensure, as near as practicable:
    • each state and territory gains representation in the House of Representatives in proportion to its population, and
    • there is a similar number of electors in each electoral division for a given state or territory.

Compliance with legislative requirements

  1. 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 (relative population change),
    • 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 more than ten per cent for a period of more than two months, or
    • a period of seven years has elapsed since the last redistribution was determined.1
  2. The procedures to be followed in conducting a redistribution process are also specified in the Electoral Act. Appendix A summarises the legislative requirements that have been followed in conducting this redistribution. Each of these requirements is discussed in further detail in this Chapter.

Background to this redistribution

  1. The steps followed from the commencement of the redistribution of Western Australia to the release of the Redistribution Committee’s proposed redistribution are outlined in Chapter 1 of the Redistribution Committee’s report: Proposed redistribution of Western Australia into electoral divisions.2

Requirement to conduct a redistribution of electoral divisions in Western Australia and commencement

  1. On Thursday 13 November 2014, the then acting Electoral Commissioner made a determination under sub-section 48(1) of the Electoral Act of the number of members of the House of Representatives to which each state and territory would be entitled at the next general election.3
  2. As a result of this determination, Western Australia’s entitlement has increased from 15 to 16 members of the House of Representatives.
  3. In accordance with sub-section 59(1) of the Electoral Act, the Electoral Commission published a notice in the Commonwealth Government Notices Gazette (the Gazette) on Monday 1 December 2014 directing the commencement of a redistribution of Western Australia into 16 electoral divisions.

Current enrolment quota

  1. Section 65 of the Electoral Act requires the Electoral Commissioner, as soon as practicable after the redistribution process commences, to determine the current enrolment quota using the following formula:

Number of electors enrolled in Western Australia as at the end of the day on which the redistribution commenced (Monday 1 December 2014)


Number of members of the House of Representatives to which Western Australia is entitled

  1. In calculating this quota, sub-section 65(2) of the Electoral Act provides that:
    • where the result is less than 0.5, the number is rounded down to the nearest whole number, or
    • where the result is equal to or greater than 0.5, the number is rounded up to the nearest whole number.
  2. Table A shows the figures used to calculate the current enrolment quota and the resultant range of the permissible maximum and minimum number of electors in an electoral division (discussed further in the section titled ‘Statutory requirements for the making of a redistribution’).
Table A: Current enrolment quota and permissible range for Western Australia
Number of electors enrolled in Western Australia as at the end of the day on which the redistribution commenced (Monday 1 December 2014) 1 504 413
Number of members of the House of Representatives to which Western Australia is entitled 16
Current enrolment quota for Western Australia 94 026
Permissible maximum number of electors in an electoral division
(current enrolment quota + 10 per cent)
103 428
Permissible minimum number of electors in an electoral division
(current enrolment quota – 10 per cent)
84 623
  1. The then acting Electoral Commissioner signed a written instrument on Monday 8 December 2014, as required by sub-section 65(1) of the Electoral Act, determining the current enrolment quota of electors for the purposes of the redistribution to be 94 026.
  2. As part of the redistribution process, the augmented Electoral Commission is required to ensure that the number of electors in an electoral division does not vary by more than or less than 10 per cent from the current enrolment quota (see Appendix B).

Enrolment projections and projected enrolment quota

  1. When determining a redistribution, the augmented Electoral Commission is required by paragraph 73(4)(a) of the Electoral Act to ensure, as far as practicable, that the number of electors enrolled in an electoral division at the projection time will not vary by more than or less than 3.5 per cent of the projected enrolment quota.4 The projected enrolment quota is calculated using the following formula:

Estimated total number of electors enrolled in Western Australia at the projection time (Wednesday 8 February 2017)


Number of members of the House of Representatives to which Western Australia is entitled

  1. Table B shows the figures used to calculate the projected enrolment quota and the resultant range of the permissible maximum and minimum number of electors in an electoral division at the projection time (discussed further in the section titled ‘Statutory requirements for the making of a redistribution’).
Table B: Projected enrolment quota and permissible range for Western Australia
Estimated total number of electors enrolled in Western Australia at the projection time (Wednesday 8 February 2017) 1 594 973
Number of members of the House of Representatives to which Western Australia is entitled 16
Projected enrolment quota for Western Australia 99 686
Permissible maximum number of electors in an electoral division at the projection time (projected enrolment quota + 3.5 per cent) 103 175
Permissible minimum number of electors in an electoral division at the projection time (projected enrolment quota – 3.5 per cent) 96 197

Release of proposed redistribution of Western Australia

  1. Sub-section 66(1) of the Electoral Act requires the Redistribution Committee to make a proposed redistribution, with section 67 further requiring that written reasons for the proposed redistribution be provided.
  2. In its report Proposed redistribution of Western Australia into electoral divisions, the Redistribution Committee outlined its proposed redistribution of Western Australia and in Chapter 2 explained the reasons for its proposal.5 On Friday 21 August 2015, this report was made available on the Australian Electoral Commission (AEC) website and at each office of the AEC in Western Australia.
  3. In addition, and as required by sub-section 68(1) of the Electoral Act, the following information was also made available at each AEC office in Western Australia from Friday 21 August 2015:

    • copies of the 27 suggestions and 16 comments on suggestions made to the Redistribution Committee.

Invitation for interested parties to submit objections and comments on objections

  1. The Redistribution Committee is required by sub-sections 68(1) and (2) of the Electoral Act to draw attention to the redistribution material able to be viewed at AEC offices in Western Australia and to invite written objections relating to the proposed redistribution of Western Australia and written comments on objections via:
    • a notice published in the Gazette on a Friday
    • a notice published in two newspapers circulating throughout Western Australia, and
    • notices published in such regional newspapers circulating in regions affected by the proposed redistribution as determined by the Redistribution Committee.6
