Anthony Albanese has laid out his pitch for revamped income tax cuts as the changes reach a major hurdle.
The prime minister told parliament the tax changes would not leave people behind, saying the measures represented meaningful change.
"We want Australians to earn more and to keep more of what they earn," he said on Wednesday.
"People are doing it tough, and we want to do everything we can to provide support for cost of living."
The House of Representatives is readying for a late night debate before MPs cast their votes on Thursday.
The prime minister wants the tax changes to clear the Senate before Easter, given they're due to take effect in July.
Under the plan, people earning under $150,000 will receive a greater tax cut than originally planned, and those on higher incomes will get less.
The coalition complained about the changes for a week before capitulating and backing them in.
Mr Albanese said Labor's amendments would make the tax cuts fairer.
"Our tax cuts are aimed squarely at regional Australia and our tax cuts are aimed squarely at middle Australia, tax cuts are aimed at ensuring that people are not left behind," he said.
"As every Australian aspires to a better future for themselves, we will put in place measures that help them to achieve that better future for themselves and their children. That's what these tax cuts are about."
