Australian Greens Leader Christine Milne says the Prime Minister's chief business adviser, Maurice Newman, must be deaf if he hasn't heard the Greens clearly identify revenue alternatives for balancing the budget.

"Keep the carbon price, keep and fix the mining tax and get rid of fossil fuel subsidies for big polluters," said Senator Milne.

"The Greens won't allow Tony Abbott's brutal budget cuts to impact on Australians who need our support, when there are such obvious revenue alternatives.

The Australian Greens have today slammed the report from Tony Abbott's Commission of Audit which protects the big end of town while slugging families and low income earners.

"This is a hit on every family in the country, while Gina Rinehart gets off scot-free," said Australian Greens Leader, Christine Milne.

"Tony Abbott and Joe Hockey handpicked commissioners from the big end of town and rigged the terms of reference to ensure that the audit would focus on sweeping cuts to government services. And the commission has delivered precisely the report the government wanted.

The Australian Greens say Tony Abbott must come clean about his cruel cuts before voters go to the polls in elections around the country.

"How can we trust a Prime Minister who deliberately withholds information before an election?" asked Australian Greens Leader Christine Milne.

"Tony Abbott is deliberately hiding his true agenda for cruel cuts. He is being mean, tricky and secretive.

"It's completely obvious the PM is holding out until after the upcoming elections in an attempt to pull the wool over voters' eyes.
