Prime Minister Malcolm Turnbull denies he has neglected Western Australia, despite visiting the state just once in nearly a year.

As Mr Turnbull prepares to return to WA for a visit next month — his first since February — the Prime Minister also sought to deflect blame for inaction on the GST distribution to Federal Labor.

Mr Turnbull's only visit to the state since last August was a one-day stop in February ahead of the state election, a trip senior Liberals privately lamented as unhelpful to the state campaign.

But the Prime Minister rejected suggestions he had not paid enough attention to WA.

"I've spent a lot of time in Western Australia and I'll be there again for the best part of a week very shortly," Mr Turnbull told 6PR.

"Western Australia is very much part of my life. I can assure you I am not a stranger there."

Mr Turnbull will also be the main guest at a Liberal fundraiser during his multi-day visit, with attendees charged $40 to attend.

His upcoming visit is certain to prompt more questions about his government's plans for the GST distribution system, after pledging last year to introduce a "floor" level for each state's share.

That came after years of lobbying from WA, which has long complained about its low share of GST revenue, but the proposal is yet to proceed.

But Mr Turnbull sought to deflect the blame for that to Labor, saying change would not progress without a consensus.

"What we need is to put the acid on the Labor Party and say to them when are you going to stop simply taking pot shots at the Liberals?" he said.

"We have got to be able to persuade all Australians the arrangements are currently unfair."

But McGowan Government Minister David Templeman said Mr Turnbull clearly did not understand how "peeved" West Australians were, saying it was "ridiculous and ludicrous" to blame Labor.

"The Prime Minister comes across here, gives us lip service and then doesn't come back for six months," the Local Government Minister said.

"His ongoing treatment of Western Australia demonstrates how little he thinks of this state."

WA is receiving just 34 per cent of what would be its per capita share of GST revenue this year, a figure much lower than any other state.
