Opposition Leader Tim Nicholls has refused to say he'd accept One Nation support to rule if the minor party holds the balance of power after the Queensland election.
Mr Nicholls travelled to Mount Coot-tha in the new marginal Brisbane seat of Maiwar on Monday to announce $4 million for environmental incentives if the Liberal National Party takes government.
But the path to government will be rocky, with One Nation polling well in numerous electorates and neither of the major parties looking likely to hold a majority.
The LNP leader defended the party's decision to preference One Nation ahead of the Greens in 50 seats, but he would not commit to accepting support from Pauline Hanson's party to rule as a minority government.
"I've been asked that question plenty of times, my position has always been that we are going into this contest to win," he told reporters.
"We are focused on delivering majority government and the LNP is the only party that will be able to bring about majority government that will bring about the change that Queenslanders want."
Mr Nicholls also refused to name the six seats he believes the party could pick up to reach the magic 47 seats which would grant him a majority in the new 93-seat parliament, saying Queenslanders weren't interested in "political games".
He started the day apologising again to Queenslanders for his actions while treasurer in the Newman LNP government, which resulted in 14,000 public servants sacked.
Asked on ABC radio if he had a personal credibility problem, Mr Nicholls said he'd made amends.
"I've apologised and admitted and taken responsibility for my role in the previous government, as I think I should," he said.
Mr Nicholls said voters could trust the LNP's plan for the state, with the party ruling out axing public servants and leasing or selling public assets if it regains power.
