Scott Morrison has hinted the government could ramp up tax relief for Australians in next week's federal budget.
That comes as healthcare is shaping up as a key economic battleground for the looming federal election, with both major parties arguing they are the best placed to fund essential services.
Speculation is mounting that Treasurer Josh Frydenberg's first budget, to be handed down next Tuesday, will bring forward income tax cuts that have already been legislated as well as improve tax offsets for low-income earners.
Asked about the prospect of extra tax relief in the budget on Monday, the prime minister said his record for lowering taxes is clear.
"Wherever I get the opportunity to give Australians further tax relief, I never miss the opportunity," he told reporters in Melbourne.'
The government passed a personal tax cut package through parliament last June, with the first stage kicking in for the current financial year and further reductions due in 2022 and 2024.
The cuts will lead to a single person on $30,000 keeping an extra $200 a year, while someone on an average wage of around $85,000 would get $540 and a $200,000-a-year salary earner would get $7225.
Labor has opposed the higher-income tax reductions and says it will give cuts of $350 to people earning $25,000 and up to $928 for people on $90,000 a year.
"All I know is that we are offering bigger, better, fairer tax cuts," Opposition Leader Bill Shorten told reporters in Melbourne.
As Australians wait to see whether the budget will actually mean they get to keep more of their pay, both sides of politics have been busy laying out their plans to fund health services.
The government will spend an extra $496 million on cancer treatment over six years from 2018/19, including $80 million on a new national facility at Melbourne's Peter MacCallum Cancer Centre.
Labor has vowed to stop the Medicare rebate freeze it introduced when in government in 2013 a year earlier than planned if it wins the election.
The freeze has meant rebates for some services have been kept at the same rate for years, despite costs generally going up across the economy through inflation.
The measure has been ending in stages since mid-2017, and is due to finish completely in mid-2020.
Ending the freeze early will cost $213 million and mean rebates for about 100 GP items - including family counselling and mental health care - will resume going up in line with inflation.
Health Minister Greg Hunt has stressed it was Labor who brought the freeze in and the coalition that is getting rid of it.
The victory of Gladys Berejiklian's coalition government at the NSW election has also left the Morrison government more confident it can woo voters by playing up its economic management credentials.
