Prime Minister Scott Morrison has raised funds for the Liberal party's depleted coffers, campaigned in three of WA's top four battleground electorates and spruiked his GST fix during a three-day visit to the state.
Mr Morrison went to Stirling, Swan and Hasluck within the first 24 hours of the trip, and while he didn't make it to Pearce, he made sure he was flanked at the first event by the MP for the outer metro seat, Attorney-General Christian Porter.
Hasluck is the Liberals' most at-risk seat, held by Ken Wyatt with a margin of just 2.1 per cent.
Both Pearce and Swan, held by Steve Irons, have a 3.6 per cent margin, and while Michael Keenan holds Stirling with a bigger margin of 6.1 per cent, the seat is considered potentially in peril.
One MP who didn't need the prime minister to lift her profile was Julie Bishop, who holds the very safe seat of Curtin with a whopping 18.2 per cent margin.
But she still appeared alongside him in the Henderson shipbuilding district on Wednesday, when he congratulated her for her 20-year anniversary in office - a somewhat awkward moment given Ms Bishop refused to be part of his cabinet after last month's leadership spill.
As usual, Mr Morrison spent most of the trip talking about GST reform.
It's only known to an exclusive few, however, what he told a fundraiser breakfast run by the conservative 500 Club.
The event raised much-needed cash for the Liberals, who cried poor in deciding not to contest the recent Perth and Fremantle by-elections.
The decision was criticised by many in the party - including Senator Dean Smith, who appeared alongside Mr Morrison at several events this week - but it certainly freed up resources for sandbagging those other four vulnerable seats.
Former prime minister Malcolm Turnbull is not expected to remain the party's most generous donor.
