The WA Nationals say the federal party should consider a split from the Coalition.

The Nationals candidate Tony Crook is expected to win the seat of O'Connor from long-standing Liberal MP Wilson Tuckey.

He has vowed to act as an independent WA National and says he will not form part of a Coalition.

Mr Crook campaigned on a commitment to try to implement WA's Royalties for Regions scheme at a national level.

The Nationals's state president Colin Holt has told the ABC, Mr Crook will be putting WA first.

"Unless the needs of Western Australia are met in this parliament, then you can't expect Tony Crook to just freely give support," he said.

Mr Crook says while he hopes to be in a position to start negotiating with the major parties, it is early days yet.

"We need to be in that discussion, we've claimed to be an independent voice in Canberra proudly representing the WA Nationals and regional Western Australia," he said.

"That was on the agenda from day one, no one could ever doubt that it wasn't."

Mr Crook says the party will formulate its negotiating position shortly.

"We stand proudly as the WA Nationals and we've been aiming for exactly what might be panning out," he said.

"But, there's a lot of water to go under the bridge yet, the parliament's not set yet so there's a lot to presume and a lot to hope for but I think we need to get that done and dusted first."

The WA Nationals are allied to the federal Nationals party but are not required to vote along party lines.

In WA, the Nationals are also in an alliance with the Liberal party in a minority government.

Mr Holt says it is a model that works.

" We've stamped ourselves as an alternative in WA and we think that's what the Federal guys should be doing and looking at it more closely," he said.

"I think the voters out there want a third independent voice and I think that's probably shown with the Green vote in this election."
