I t won't take long for Malcolm Turnbull to notch up the first broken promise of his new term in office. It is not something the returned Prime Minister will relish - or a promise that he can, directly, avoid breaking.
"As you know I have said that the ministry I led to the election, will be the ministry I lead after the election," he said.
"Regrettably, several ministers have not been returned and so there will be some changes."
Junior ministers Wyatt Roy and Peter Hendy - both Turnbull backers who have lost their seats - will have to be replaced.
Tourism Minister Richard Colbeck is also not guaranteed a return to the Senate.
But it is not as simple as replacing those who lost.
The junior coalition party, the Nationals, did better than expected at the election and are expected to jockey for a an extra Cabinet position after a partyroom meeting today.
And there are calls for Mr Turnbull to offer plum roles to conservatives as an olive branch that could help deliver stability in a party that will govern on a knife edge.
While juggling the competing interests, Mr Turnbull should remember that WA voters went to the polls in the belief that WA Liberals would remain in some of the most influential positions in Canberra.
WA missed out on the lucrative election promises bestowed on other States and electorates eyed by party electioneers on both sides, especially Townsville, which was pledged $100 million for a sport stadium during the campaign.
The biggest inequity for WA remains the carve-up of the GST and it is essential the State continues to have a strong voice in Cabinet. WA's senior Liberals, led by ministers Julie Bishop, Mathias Cormann, Christian Porter and Michaelia Cash, must retain their positions to continue to lobby for a fair share of the GST pie.
Labor did not have any West Australians in its senior leadership team before the election and must rectify that situation now.
The loss of former resources minister Gary Gray, who retired before the election, will be keenly felt as he was a tireless advocate for the State.
While there is no WA Labor MP with the depth of experience that Mr Gray had, Bill Shorten has some strong contenders from the west for his shadow cabinet.
The first choice is probably Tim Hammond, who succeeded Alannah MacTiernan in the seat of Perth. 
An ALP vice-president and former barrister, Mr Hammond appears ready-made for a substantial portfolio.
Mr Shorten should not stop at one West Australian and also look at the potential talents of Matt Keogh, Anne Aly and others.
