Senior federal government minister Simon Birmingham is keeping the pressure on Labor and its likely new leader Anthony Albanese to back the coalition's income tax cut plan, saying people need certainty.
Senator Birmingham said the personal income tax cuts legislation would be brought forward to the new parliament at the first opportunity after the writs are returned.
"The only uncertainty about whether or not that legislation can pass swiftly really does reside with the Labor party's uncertain position at the present," he told Sky News on Sunday.
"It would be a tin ear in terms of having listened to the electorate."
Mr Albanese has already said he "will consider" supporting the entire tax plan, after previously flagging support for only the initial stages.
The opposition has previously indicated support for the first part of the plan geared toward low and middle-income earners, but not the government's aim to flatten the tax structure in 2022 and 2024 under the second and third stages of its plan.
The later tax cuts wouldn't come until after the next federal election.
"All too often I hear from the Australian people grumbles that governments don't look far enough into the future, that all we do is think about a year or two ahead or about the next election," Senator Birmingham said.
"It is one of the critical things to give long term certainty to Australian consumers and Australian businesses."
