Collie-Preston – WA 2025

ALP 23.3%

Incumbent MP
Jodie Hanns, since 2021.

South West. Collie-Preston lies to the south of Perth, covering the Collie, Dardanup and Donnybrook-Balingup local government areas, and part of the Capel council area. The coal-mining town of Collie is the largest population centre in the electorate.

Collie-Preston shifted south, gaining Balingup and Mullalyup from Warren-Blackwood and losing Peppermint Grove to Vasse and a small area to Murray-Wellington.

The seat of Collie-Preston is the successor to the seat of Collie, which existed under that name from 1904 until the name was changed to Collie-Wellington in 2005 and then Collie-Preston in 2008.

The seat was held by Labor continuously for eighty-one years from 1908 until 1989.

In 1989, the seat was by the National Party’s Hilda Turnbull. Turnbull defeated Labor candidate Mick Murray in 1993 and 1996. In 2001, Murray defeated Turnbull by 34 votes.

In 2005, Murray was re-elected to the renamed seat, and a combination of a friendly redistribution and a 6.7% swing saw him hold the seat with a 9.3% margin.

Most of Murray’s margin was wiped out in the 2008 redistribution, but Murray held on with a small positive swing, leaving him with a 1% margin. He was re-elected by only 56 votes in 2013, but won more comfortably in 2017.

Murray retired in 2021, and Labor’s Jodie Hanns won the seat with ease.


  • Jodie Hanns (Labor)
  • Assessment
    Collie-Preston looks like it has a large margin, but it is Labor’s 29th-safest seat. If there was a sufficient swing to bring the election result close to being in doubt, Collie-Preston would be one of those key seats that would decide whether Labor could retain its majority.

    1. Something really needs to be done about the dividing of Australind into 2 districts as a former resident I can tell you that it should be in 1

    2. I have never resided in this area, but looking purely at primary vote numbers, it seems like Balingup’s high primary for the Greens and Nationals is very out of step with the rest of the electorate. Maybe it’s better off being in Warren-Blackwood with its neighbours Nannup and Bridgetown, both of which have more similar voting patterns to Balingup than anywhere else in Collie-Preston.

    3. @Wilson I heard that last election a lot of locals of the Balingup area attempted to vote in Donnybrook because it’s the same local gov area and many simply had no idea it had been divided between seats

    4. This would surely have to be the only coal mining area that is voting more pro-Labor now than it did 10 years ago?

    5. @mostly imagine how people in Australind feel it depends on which side of the main road you live to which district your in

    6. I believe you can technically build a second seat out of the Bunbury suburbs like Australind and Eaton but to do that you would also have to create a seat that combines the remainder of Murray Wellington and Collie Preston and I doubt the WAEC wants to deal with more regional anger after this cycle

    7. @mostly the main problem is putting all of Australind together as I suggested you put all of Australind together with Dardanup and collie. Problem solved Murray Wellington then moves into the dawesville gap

    8. A theoretical marginal seat which needs a 23% swing to change hands. Shows there is a long way to go for
      The libs to be competitive

    9. What effects could the end of coal fired power have on this seat and the vote in collie. If the libs brought nuclear power here could that sway votes

    10. The issue is whether the Libs are willing to sacrifice Nedlands, Churchlands, Cottsloe etc to potentially win this seat. I expect Teals do campaign against both parties since State Labor does not have a 2030 target and WA is the only state where emissions have increased since 2005.

    11. @Nimalan that is a valid point as those seats are very important for the Liberals. I expect WA Labor to announce a 2030 target soon and the Coalition will follow suite.

      It’s risky because this is a very working-class industrial seat and Collie itself has always heavily voted Labor. It’s like the Cessnock or Gladstone of WA. On the other hand, those seats Nimalan mentioned are affluent, blue-ribbon beachside seats in the northwestern suburbs of Perth, comparable to seats like Manly and Vaucluse in Sydney or Surfers Paradise on the Gold Coast.

    12. Just to give context, in 2022 (even with a progressive leader, in this case Albo, though WA did swing to Labor because of Mark McGowan, a more centrist Premier, on the state level), Collie voted heavily Labor:

      Labor TPP in Collie booths:

      * Collie: 67.77% (+6.98%)
      * Collie Central: 68.55% (+10.75%)
      * Collie North: 71.04% (+9.35%)
      * Collie PPVC: 67.25% (+8.24%)
