Mr Grylls and Liberal leader Colin Barnett were due to meet at WA's Parliament House this morning, following a meeting of Mr Grylls and Labor leader Alan Carpenter yesterday.

The meetings come as WA's vote continues to be counted, with no clear leader and the Nationals the likely key to either major party forming government.

Mr Barnett said he expected an amicable discussion but Mr Grylls has said his team was not allied to either of the major parties.

Mr Barnett said that Mr Grylls was in a pivotal position, but had a strong responsibility on his shoulders to ensure the will of the people was carried out.

"He now is a significant player in West Australian government in the coming term," Mr Barnett said.

Mr Barnett said it was not just a matter of talking about an amount of money the Nationals wanted for the royalties for regions program, but also discussing the approach a new government would take.

"I think firstly it's about principle and the direction we will take if we do find ourselves in government," Mr Barnett said.

The Liberals and Nationals had historically governed together successfully, Mr Barnett said.

But Mr Grylls said talk of a backlash from his voter base if he joined with Labor to form government was not a consideration.

"We do not have an allegiance to Liberal and we do not have an allegiance to Labor," he said.

"I do not feel pressured by anyone that we have to do a deal with the Liberals."

Mr Grylls said he would be pressing for incentives for mining exploration, a substantial regional housing program and the best outcome for regional people.

Edith Cowan University political analyst Dr Harry Phillips said whatever way the Nationals went they would have to have a licence in the agreement with Alan Carpenter or Colin Barnett to differentiate on a couple of key issues sensitive to the Nationals.

Dr Phillips said Labor had been damaged in the election and the Nationals had a delicate decision to make.

"If they find they are signing up an alliance with a party that may be on the slide, that is a great danger and this strategy may rebound on them," Dr Phillips said.

He said there was slightly greater safety for the Nationals in supporting a Liberal-led alliance with Colin Barnett.
