Proposed boundary changes 'biased': MLA

Labor MLA Mick Murray would face an uphill battle to retain his Collie-Preston seat in the WA Parliament if the Liberal Party's suggestion for a boundary reshuffle is adopted.

The Liberal Party has called for Mr Murray's power base hometown of Collie to be moved into the neighbouring seat of Wagin, held by the National Party's Terry Waldron.

Mr Murray's seat - also containing Australind and Eaton - would then be renamed Preston under the Liberal proposal.

Mr Murray told the Bunbury Herald the move was "biased" because the Liberals wanted to claim his seat.

"Honestly, every time we have a redistribution, the Liberals trot out the same thing," Mr Murray said.

But Liberal Party WA director Ben Morton said it made sense for Collie and Boddington to be shifted into the Upper House's Agricultural region.

"We think it is a very obvious and natural submission," Mr Morton said.

The Labor Party has suggested minor changes only to electoral boundaries in the South West and the National Party wants no change at all.

The submissions have been made for the Electoral Distribution Commissioners' review of WA electoral boundaries, which will come into effect at the 2017 State Election.

Submissions closed last week, with the proposed boundaries set to be released in July and the final boundaries released no later than November 30.

Each of the 59 electorates in WA must have about 25,000 constituents in each district, though there are some exceptions for seats of an area greater than 100,000sq km.

In a discussion paper, the EDC identified three options for boundary changes - including major change, incremental change or no change to boundaries.
