The prime minister has stopped short of funding the Liberal National Party's centrepiece election policy of widening Queensland's Bruce Highway.
Scott Morrison on Saturday joined state LNP leader Deb Frecklington on the campaign trail for the first time on the Gold Coast.
Ms Frecklington wants to widen 1450km of the highway from two to four lanes with 80 per cent of the $33 billion project to be funded by the federal government.
The federal budget allocated $20 million for a $50 million Bruce Highway study, but the prime minister is yet to commit the bulk of the funds.
"What we have done in this budget is we've set up a longer term design and plan that can support the type of program that Deb's laid out," Ms Morrison told reporters in Currumbin.
"So we're getting ready for should Deb be elected, and the LNP be elected, here soon, which is a decision for Queensland as of course."
State Treasurer Cameron Dick mocked Ms Frecklington, saying "it was all smiles for the cameras" but the prime minister had come empty-handed.
"(The) Bruce Highway plan is a highway hoax, and that was underscored and underlined yet again today," he said.
Mr Morrison did promise that infrastructure funding will be streamlined if his ally wins the October 31 election.
The prime minister accused the Labor government of "picking fights" and holding up funding deals for major projects.
"I'm not looking to pick fights with anyone in Queensland, I just want to get things done," Mr Morrison said.
"And if Deb Frecklington's elected, then I can tell you what, that's going to really change things up here in Queensland because we're going to be able to get moving."
He admitted Premier Annastacia Palaszczuk played "an important role" at national cabinet.
But he bemoaned the difficulties in getting road funding deals across the line with the state government.
"I announced those with the premier and I appreciate that because it took a long time to get there," he said.
"I suspect Deb and I will come to an agreement a lot more quickly than that because she's not looking to pick a fight with me, or carry on with any politics."
Ms Palaszczuk was also on Glitter Strip to pledge a $30 million funding boost to Surf Life Saving Queensland.
She says the prime minister is always welcome in her state, but insisted that his visit wouldn't sway voters.
"Queenslanders are smart people, they know it's a state election, it's not a federal election, it's a state election," the premier said.
"Queenslanders also know there's been one party, and one government, that's been absolutely focused on protecting them and keeping them safe."
Ms Palaszczuk also said she would always welcome Labor ally and federal opposition leader Anthony Albanese in her state.
Queenslanders go to the polls on October 31.
