Veteran West Australian state MP Mick Murray has revealed his plans to stand down at the next election, after marking two decades in parliament.

The lower house member for Collie-Preston was first elected in 2001 and currently serves as minister for sports and recreation, seniors and ageing, and volunteering.

He'll remain in those positions until the 2021 state election, Premier Mark McGowan announced on Sunday after Mr Murray revealed he would not-recontest his seat.

"Mick is most recognised as a fierce, straight-talking advocate for the people of Collie-Preston," Mr McGowan said.

"I recent years, Mick has fought on behalf of his community to ensure Collie has a prosperous future, at a time of great uncertainty due to the changing local economy."

The electorate south of Perth includes suburbs of Bunbury as well as the towns of Collie, Capel, Donnybrook and Kirup.

At the 2017 election Mr Murray received 49.48 per cent of total votes and retained his seat with 64.71 per cent on a two-party preferred basis
