The Queensland government is set to come under scrutiny for major increases in health and infrastructure spending as it wrestles with $83 billion in state debt.
Annastacia Palaszczuk has revealed ahead of Tuesday's budget that health spending will rise by almost $800 million from last year to a record $18.3 billion.
The premier also spruiked a $45 billion spend on infrastructure last month - levels not seen since the 2011 flood recovery.
Treasurer Jackie Trad has claimed the debt is the inevitable result of the government's plans to futureproof the state against a growing population, but the opposition believes the government is at risk of losing control.
"The real question for Jackie Trad on Tuesday is what is she going to do about structural debt here in Queensland," opposition MP Christian Rowan said.
"She's also foreshadowed four new taxes and a waste levy as well.
"Simply, you can't tax your way out of all your problems."
The four new taxes included in Ms Trad's first budget are expected to raise $163.3 million a year over the next three years to pay down debt.
It will mean a hike for the owners of luxury cars, a new land tax category for large holdings, higher stamp duty for foreign buyers of property, and a new betting tax targeting agencies based outside the state.
"We have said we would be be responsible economic managers," Ms Palaszczuk said on Sunday.
"But we also need infrastructure built across Queensland. We are a decentralised state and families want services."
