Frustrated and disempowered, Chris Shannon is among a small but possibly crucial percentage of West Australians lining up behind the resurgent One Nation party.

Chris and his partner Anita from Baker's Hill, east of Perth, say they will be opting for Pauline Hanson's party if it fields candidates at the state election in March.

"The Liberal Party don't listen, the Labor Party don't listen," Mr Shannon told the ABC.

"What else are people going to do?"

Polling has shown support for One Nation has surged since the July federal election, and the party would secure 6 per cent of the Lower House vote in Western Australia.

And its preferences could have an impact on the election outcome.

Mr Shannon, a software developer, has voted Liberal in the past, even handing out how-to-vote cards for the party in New South Wales.

The 50-year-old has also been known to vote for Labor.

But he says he has lost faith in the major parties, and is scathing about the performance of WA's Liberal-National alliance.

"I think the economy in Western Australia is completely stuffed," he said.

"How can you have all those companies taking all those resources, making trillions of dollars on their sale and end up with ... Western Australia $36 billion in a deficit.

"And claim under your state constitution that somehow you have provided good government?"

Mr Shannon voted for One Nation's WA senator Rod Culleton at the federal poll, mainly because of the former farmer's crusade for a royal commission into the banking sector.

The couple, who say they are themselves victims of "mortgage fraud", do not approve of the party's anti-Muslim stance, but agree with enough other policies.

"I see non-representative government everywhere I look," Mr Shannon said.

"Being the only alternative that seems to be interested in listening to the people of Australia, the constituency, asking them what they want and then formulating policy upon the responses it's getting, I will be voting for that."

'Disaffected voters' in country regions

But One Nation has not yet registered as a party in WA, and time is running out.

Political analyst Peter Kennedy said if it does meet the November 1 deadline and field candidates, the impact could be significant.

"In a sense they are a bit dysfunctional but in another sense the supporters don't worry about that," Mr Kennedy said.

"I think One Nation's impact will be strongest in the country and that's where the Liberal and National [parties] will be slugging it out in many seats.

"That's where I think most disaffected voters are."

Analysts point to the 2001 state election, when amidst angry anti-racism protests the party achieved nearly 10 per cent of the statewide vote, and Liberal Premier Richard Court lost government after two terms.

Former One Nation MP Frank Hough, who won his Upper House seat that year, can see the parallels.

"We could feel when One Nation kicked off, we could feel that there was going to be a change," Mr Hough said.

"You could feel it in the air.

"They were seriously disillusioned with the Richard Court government.

"The whole sentiment today is a blueprint.

"The Premier would probably feel that in his bones now."

Colin Barnett said there was clearly support for One Nation, given the state had just voted in one of the party's four senators, but he is not worried.

"I'm not stressing about One Nation," Mr Barnett told reporters this week.

"My opponent is the Labor Party.

"That's the contest."

But Mr Kennedy points to history and the power of the anti-major-party protest vote.

"It was Richard Court's Liberal-National party government which felt the full brunt of One Nation's decision in 2001 to preference against sitting members," he said.

"If they decide to do that again this time, it might be Labor who will be the beneficiaries."
