Liberal leader Colin Barnett says Nationals voters would expect a Coalition government.
With no party likely to get an absolute majority after yesterday's election, much depends on the Nationals and independents who will hold the balance of power in the lower house.
Neither Mr Barnett nor Premier Alan Carpenter have claimed victory or conceded defeat. There was no vote counting today, with the WA Electoral Commission to resume tomorrow, but at this stage there has been a 6pc swing against Labor.
Labor believes the result is a lot closer than it appears at present and is not conceding seats such as Riverton, Morley or Kwinana, while it is in front in seats such as North West and Collie-Preston.
The Nationals, which will have four seats, would normally be expected to form a coalition with the Liberals.
Both parties could be able to form a majority with the help of Liberal-leaning independents if Labor does lose some of those seats.
But Nationals leader Brendon Grylls has refused to bow from his stance of supporting the major party which backed his "Royalties for regions" plan, which would see 25pc of the State's mineral royalties quarantined to be spent in regional areas.
"Rather than talking about being a minister at the front bench, I need the two major political parties, Labor and Liberal, to focus on... royalties for regions," Mr Grylls said.
"Once we have put that on the table and seen some agreement from either Labor or Liberal then we can discuss the mechanics of how we put that together."
Neither major party had "shown any interest" in the plan.
However, Mr Barnett who had tried unsuccessfully to call Mr Grylls this morning, said Nationals voters would expect a Coalition government.
He hoped to meet with Mr Grylls either later today or tomorrow. Mr Carpenter will meet with Mr Grylls this afternoon.
"If you look at last night's election results, the first conclusion that must be drawn is that electors rejected the Labor government," Mr Barnett said.
"I wouldn't say (the Liberals are in the) box seat, but I think the Liberal Party is in a stronger position (than Labor)."
"I believe both Nationals party and Liberal party voters want to see a new government, and they want to see a Liberal Party-Nationals Party government of some sort."
A "lot of money" was already spent on regional areas, "but clearly voters have expressed at the ballot box not enough is spent on country towns", Mr Barnett said.
"The towns developed in the 60s and 70s have not been kept up," he said.
"I'm certainly willing to increase funding to regional areas (but) I'm not going to debate here amounts of money."
Any government needed to be stable, otherwise it would be "the worst outcome" for the state.
"I wish I had the result. This is frustrating... like a tied Grand Final," he said.
He was confident the Liberals could work with Carol Adams, who could win the seat of Kwinana as an independent after missing out on preselection for Labor. Liberal preferences could see her overtake Labor candidate Roger Cook.
Mr Barnett ruled out seeking support from former Labor MP John Bowler, who is expected to win the seat of Kalgoorlie on Liberal preferences.
However, Mr Barnett conceded the Liberals would have won the seat had he been able to persuade former leader Matt Birney not to retire from politics.
