Senator Richard Di Natale is the Chair of a Senate Committee that has been set up to scrutinise the work of the Abbott Government's Commission of Audit.

The Senate Inquiry is injecting some much needed transparency into the commission's process for developing recommendations, it is testing the underlying economic assumptions that guide their work and it is examining the real impact of cuts to services.

The Senate Select Committee into the Abbott Government’s Commission of Audit has today handed down its final report, which focused primarily on tax concessions.

Australian Greens Senator and Chair of the committee, Dr Richard Di Natale said that the report exposes how much money could be saved without making life harder for the most vulnerable people in our community.

“The budget tells you everything you need to know about the Abbott Government’s values and priorities,” said Senator Di Natale.

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.

Richard talked to Jon Faine about the Commission of Audit and the budget.

Today the Australian Greens have released an alternative vision for the budget to the cruel cuts recommended by the Commission of Audit.

“We need to have a debate about the challenges in Australia’s future but instead the Commission of Audit was a piece of political theatre where ideology trumped facts,” said Greens Senator Richard Di Natale, chair of the Senate Select Committee into the Abbott Government’s Commission of Audit.

Australian Greens health spokesperson and chair of the inquiry into the Commission of Audit, Dr Richard Di Natale, said today that allowing Private Health Insurers to charge more depending on someone’s weight and other “lifestyle factors” would be a big mistake.

“Charging people more for health insurance based on risk factors like weight is a prescription for a health system that is more expensive and less fair,” said Senator Di Natale, a doctor and former public health professional.

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 Senate Inquiry into the Abbott government's Commission of Audit has today tabled a new interim report, which covers evidence presented on the effects of predicted budget cuts in the areas of health, social services and employment.

"The evidence received by the Committee directly contradicts the Government's line on the economy," said Senator Richard Di Natale, chair of the Senate Select Committee conducting the inquiry.

Australians will sleep less easily tonight after Treasurer Joe Hockey's speech on the Commission of Audit.

Greens Acting Leader Adam Bandt says Australians can look forward to a more insecure future after the May 13 Budget, courtesy of Tony Abbott.

"Make no mistake, the Australian way of life is under threat like never before," Mr Bandt.

"This is a callous shopping list of cuts to some of the country's most vulnerable people. They will deliver for the Abbott government's mates at the expense of everyday Australians.

Australian Greens Senator and Chair of the Senate Inquiry into the Commission of Audit, Dr Richard Di Natale, announced today that his Senate Committee will hold a hearing in Perth next Tuesday.

“Forget budgie smugglers, Mr Abbott is starting to look like a budget smuggler,” said Senator Di Natale.

“The Commission of Audit’s first report must contain some explosive recommendations for brutal cuts in the budget. Why else would Tony Abbott be so determined to keep West Australians in the dark before they vote?
