Western Australia's Liberal opposition is continuing to withhold its policy costings despite a surge in early voting for next weekend's election.
More than 200,000 West Australians have already cast their ballots ahead of the March 13 poll.
Friday is the deadline for policies to be submitted to Treasury for costing but the Liberals have indicated they won't be using the agency.
Opposition Leader Zak Kirkup says their promises will be costed by an unidentified third party and released to the public "next Wednesday or Thursday".
"We want to make sure that all of our policies are appropriately costed. I'm very confident in our costings process," he said.
Treasury estimates the policies submitted by Labor to date will add $2.2 billion to net debt over the next four years.
The final number will be published next week.
Federal Labor leader Anthony Albanese is due to meet with Premier Mark McGowan on Friday after the pair raised eyebrows the previous day by holding separate media events.
Mr Albanese, who toured BHP's Kwinana nickel refinery with local federal MP Madeleine King, laughed off suggestions he was being snubbed by the popular premier.
"Mark McGowan's in a state election campaign that's about state issues," he said.
Prime Minister Scott Morrison has opted not to visit WA, leaving Mr Kirkup to fight for himself in his first campaign as leader.
The beleaguered WA Liberals have also faced a lack of support from the business community.
Property developer and Liberal Party member Nigel Satterley co-sponsored a glitzy fundraiser for WA Labor on Thursday night.
Mr Satterley has emerged as a strong backer of the premier in recent years while heavily criticising WA Liberal powerbrokers.
Neither major party has indicated support for WA following the lead of other states and outlawing political donations by property developers.
