Introduction

Under the provisions of the Constitution, the electors of Australia are required to have equal electoral representation. The Commonwealth Electoral Act 1918, requires the Australian Electoral Commissioner to determine: the number of divisions for each state and territory; the quota of electors for each state and territory; and, the minimum and maximum allowable voters in each division of a state or territory.⁽¹⁾

On 17 November 2005, the Electoral Commissioner determined that a redistribution was necessary in the states of Queensland and New South Wales (NSW).⁽²⁾ Continuing high population growth in Queensland and slower than average population growth in NSW means that this redistribution will increase the number of electoral divisions in Queensland to 29 and decrease the number in NSW to 49.⁽³⁾

The proposed boundaries for each state were released on 23 June 2006 (Queensland)⁽⁴⁾ and 30 June 2006 (NSW).⁽⁵⁾ After consideration of objections, the final determination for both States is expected to be announced on 30 November 2006.

This Research Note describes the proposed redistributions. The possible electoral impact—by converting the two-party preferred (2PP) vote from the 2004 Federal Election onto the proposed boundaries⁽⁶⁾—is discussed and a revised electoral pendulum is attached.

QUEENSLAND

At the last redistribution in 2003 the population growth in Queensland was centred in the far south-east corner (resulting in the creation of the new outer metropolitan division of Bonner). Since then, the greater population growth has been in the coastal areas from the Sunshine Coast to Cairns. There is also high continuing growth in the region around south-west Brisbane and Ipswich.

The Redistribution Committee believed that this large population growth, which is projected to continue, in the North/Central Queensland divisions of Herbert, Capricornia and Hinkler (and extending down into the Sunshine Coast) meant the new division should be situated in this region.

New division of Wright

A new division of Wright—named after the poet and social and environmental activist, Judith Wright (1915–2000)—is proposed for Central Queensland based on the coastal city of Gladstone and extending westward as far as Winton.

Wright has been created mainly from the current division of Hinkler, with large portions of Maranoa and Capricornia and a very small contribution from Wide Bay. It is not surprising that Wright is notionally a fairly safe Coalition (National Party) division with an estimated 2PP vote of 56.8 per cent.

Major vote changes

Table 1 compares the 2004 2PP votes with these proposals. There are two divisions—Bonner and Ryan—that are unchanged and a number of others, mainly in and around Brisbane, are largely unchanged. However, there are four divisions with changes in their 2PP vote of 2.0 percentage points or more—Blair (5.5 per cent to ALP), Hinkler (3.4 per cent to Coalition), Oxley (2.6 per cent to Coalition) and Fisher (2.0 per cent to ALP). Despite this, no divisions have notionally changed party status.

Note: Kennedy is a notional LP/NP division on a two-party preferred basis but is held by an Independent.

The division of Blair has experienced the largest notional change, moving it from a safe to a marginal Liberal Party division. It has lost Coalition voting areas to Dickson and Maranoa while picking up Ipswich Labor voting areas from Oxley. Hinkler loses half of its electors to the new division of Wright (helping to make Wright a notional National Party division); however, Hinkler has picked up Hervey Bay National Party voters from Wide Bay, turning it into a fairly safe National Party division. Oxley is still a fairly safe Labor division, but has mainly lost ALP voters, from Ipswich, to Blair while picking up Liberal voters from Moreton. Fisher has remained a very safe Liberal division, but has lost a higher proportion of Coalition voters to Longman than it has picked up from Fairfax.

Next redistribution in Queensland 

The Redistribution Committee has decided that the next projection date for enrolments will be only one year after the expected 30 November 2006 determination of this redistribution. ⁽⁷⁾The current trend in Queensland’s population growth leads the Committee to believe that Queensland may be entitled to an additional electoral division at the next determination expected in November 2008.

NEW SOUTH WALES

The shares of the State’s enrolment in the northern and southern coastal areas are projected to continue to grow while the north-west will decline. Greater Sydney, as a whole, is also declining slightly despite the pockets of growth in the outer metropolitan areas.

Loss of an electoral division

As the inland areas of NSW have been growing more slowly than the rest of the State, and the Federation divisions of Parkes and Gwydir have ‘the lowest projected enrolment and the greatest variation from the State average,’ it was decided that ‘there were insufficient electors … to retain these two divisions.’⁽⁸⁾

The proposal is to abolish Gwydir, which means that nearly 81 300 currently enrolled voters need to be transferred to other divisions. These voters have been spread between five existing divisions (the number transferred shown in brackets): Parkes (47 919), Calare (20 129), Hunter (9 039), New England (4 023), and Macquarie (158).

Major vote changes

The loss of an electoral division and the consequential transfer of its electors can have a major impact on many other electoral divisions. The Redistribution Committee has needed to move 695 000 electors, or 16 per cent of total enrolled, to other divisions. The estimated electoral impact of the proposed boundary changes can be seen in Table 2.
