A senior WA-based Liberal Minister has acknowledged the Turnbull Government has to woo back voters in the west, amid anger over the state's continued low share of GST revenue.

Justice Minister Michael Keenan made the comments ahead of a prolonged visit by Malcolm Turnbull and his Cabinet to Western Australia next week — just the Prime Minister's second trip to Perth in 11 months.

Mr Turnbull will visit Perth and a handful of regional centres during his week-long stay.

His last visit to Perth in February was dominated by debate over the state's GST share, amid continued anger about WA's dwindling share of revenue from the tax.

WA gets just 34 per cent of what would be its per capita GST share, a figure much lower than any other state.

Mr Keenan admitted the GST would be a big issue for the trip, but denied it would overshadow the Cabinet's visit.

"I know there is disappointment," Mr Keenan said.

"It will be a good opportunity for the PM and Cabinet to hear that directly."

Liberals in WA have long been concerned a feeling among voters that the Government has failed to resolve the GST problem could hurt the party at the ballot box — with several key seats held by narrow margins.

The seats belonging to Mr Keenan, Social Services Minister Christian Porter and Aged Care Minister Ken Wyatt are among those that would be in doubt if there was a swing away from the Liberals at the next election.

But Mr Keenan defended the Liberals' handling of the GST issue, pointing to a series of top-up payments made to WA and the Productivity Commission's ongoing review of the distribution model.

"We are the only political party that has acknowledged the problem, we are the only political party that has done anything about it and we are the only ones that have got a strategy to fix it over time," Mr Keenan said.

"We have returned over $3.5 billion to the WA state budget."

Show us the money: Wyatt

Treasurer Ben Wyatt said Mr Turnbull would be "run out of town" unless he came with more money for WA.

He suggested the Commonwealth boost funding for the state's proposed Metronet public transport system to make partial amends for the GST situation.

"It is time to stop topping that up to make up for the fact that WA is, by and large, funding three to four other states," Mr Wyatt said.

"Western Australians aren't interested in a listening tour, they are interested in a visit for the Prime Minister that actually results in some decisions that benefit West Australians."

Earlier this year, the Commonwealth agreed to redirect funds previously set aside for the Perth Freight Link to other infrastructure projects in WA — including part of the McGowan Government's Metronet public transport plan.

Treasurer Scott Morrison said there would be no announcements on the GST during his visit to WA — citing the ongoing Productivity Commission review — but admitted the Government would hear plenty about the issue.

"The real measure of this visit is to shut up and listen, and that is what we are going to do," Mr Morrison told 6PR.
