Cabinet ministers have also expressed unhappiness over a new tax, but have not gone on the record with their concerns. As The Australian Financial Review reports, cabinet is split on the idea of the tax, which is reported to be aimed at middle- and high-income earners.
It has been reported that the tax would only target those earning at least $150,000, in a bid to appease concerns that families on lower incomes would be unfairly hit in the budget
On Wednesday, Assistant Minister for Infrastructure Jamie Briggs described Ms Gambaro's comments as "pre-emptive", and said the Queensland MP did not know the detail of the budget.
"I think it would be wise for Teresa to wait until next Tuesday to start expressing views," he told Sky News.
With her comments on Wednesday, Ms Gambaro also joins other Coalition figures who have voiced their opposition to a deficit levy.
These includes former treasurer Peter Costello and former Howard era ministers Peter Reith and Amanda Vanstone.
Labor, the Greens and the Palmer United Party have all indicated they would block a deficit levy in the Senate.
