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

Mick Murray never held it by much except in 2005. And of course 2017 in the landslide.
