The budget is expected to see a boost in infrastructure spending, an increase in personal tax cuts and some direct payments for voters to address cost-of-living concerns
The budget is set to play a key role in the May election, which may be called in the coming days, with the Coalition looking to sway voters after recent opinion polls have consistently shown they are headed to a defeat.
Treasurer Josh Frydenberg says the budget will set Australia up for the next decade.
But Labor leader Bill Shorten says it's the mining industry and Australian workers who have done the hard work, as the Treasurer prepares to release a budget that's in surplus.
Mr Shorten has accused the Coalition of playing catch-up on Labor's tax policies.
He says he isn't convinced this budget will mean much.
