A poll predicting a Labor win in the WA election is disappointing for the Liberals but two-term Premier Colin Barnett says the party is still in the game because of undecided voters.
A Galaxy poll commissioned by Seven West Media shows Labor has a 54 to 46 per cent lead over the Liberal-National alliance on a two-party preferred basis.
"I'm a little bit disappointed but I think it confirms what most polls have indicated, and while there's been a great deal of variability within the polls, it's clear that the Labor party has been in front," Mr Barnett told reporters.
"A large number of voters, maybe 15-20 per cent, have yet to decide how they're going to vote so we're still in this game."
Mr Barnett has previously labelled Opposition Leader Mark McGowan boring and took a similar swipe on Sunday.
"Mark's OK, he works hard but I tell you what, Western Australia is headed for mediocrity," he said.
The premier again accused Labor of being at the behest of the unions, which had helped attack the Liberals in advertisements and would "want a direct say in all government decisions".
"Probably two-thirds of a McGowan cabinet will be recent union officials," he said.
It was fitting, then, that Labor embraced its roots with former trade union chief and prime minister Bob Hawke being interviewed by Mr McGowan at a town hall forum in the CBD.
Mr Hawke, who led the country after serving just two years in parliament, gave Mr McGowan advice for if he were to seize power on his second attempt this Saturday.
"Politicians are always thinking about talking. But listening is a very important part of leadership," he told the 49-year-old.
Federal Labor leader Bill Shorten is expected to return to Perth for the campaign's final week but Prime Minister Malcolm Turnbull won't.
His recent visit flopped because he was seen to have backtracked on a promise to fix the GST system that short-changes WA.
Mr Barnett said he was unfazed.
"No that's fine. He came over and paid a visit, John Howard made a visit, a few federal ministers have come over, it's good, but this is a state campaign so we're running on our record as a state government."
One Nation leader Pauline Hanson flew in on Sunday night for a full week of campaigning in WA, mainly in the regions.
The poll shows One Nation on nine per cent.
"I do believe we will win seats in the upper house, especially as the Libs are preferencing us before the Nats and Labor," Senator Hanson told ABC TV.
She also called a third candidate to quit over the Liberal deal, Ray Gould, a Labor stooge for his public outburst.
"He has come across to One Nation as a disgruntled person."
Mr Barnett said he didn't regret the deal.
"It doesn't mean in any way that I support One Nation candidates or One Nation policies because in most areas, I do not," he said.
