The Greens will try to force Treasurer Joe Hockey to release detailed modelling prepared before the budget that shows the likely impact of the proposed measures on different household types.
Greens push for release of Treasury documents
The Greens will try to force the government to release secret budget modelling says Adam Bandt
The Abbott government is refusing to release two documents – one of 56 pages and one of 21 pages – prepared by Treasury in the lead-up to the budget, which it is understood show clearly how in the budget, less wealthy households would suffer far bigger falls in disposable income than richer ones.
Documents released under freedom-of-information legislation to Fairfax Media show the government delivered its budget fully aware its spending cuts would hit poorer households hardest.
But the Treasurer's office is withholding more detailed analysis prepared by Treasury – a "distributional analysis of prospective policy measures" and a "cameo-analysis of impacts of the 2014-15 Budget measures" – saying they were prepared for cabinet and were therefore protected from FOI.
But on Tuesday acting Greens leader Adam Bandt the Greens will try to force the government to make the documents public when Parliament resumes.
"We will move in the Senate to require the government to produce these documents so the Australian population can see just how unfair this budget is," Mr Bandt told reporters in Melbourne.
Mr Bandt said Mr Hockey and Prime Minister Tony Abbott had been ''caught out''.
"They stood up on budget night and said this was a fair budget. That was a lie. They have hid the figures that show low income households and families are going to have to pay more than middle and high income families to meet the cost of the government's attacks,'' he said.
Labor leader Bill Shorten on Tuesday said the government was blaming others for its budget problems.
"We've seen the Abbott government turn and attack the media for the losses in its budget," he said.
The Greens will need the support of Labor and four independent senators for the motion to pass in the senate.
Labor Senate leader Penny Wong said Labor had already used Senate estimates to ask the Treasury for a copy of the distributional analysis it carried out on the budget, but to no avail.
''This information has been published in every budget since 2005 yet now Mr Hockey is going to extraordinary lengths to hide the facts about his own budget,'' Ms Wong said.
''We will continue to demand that the government tell the truth about the budget.''
Parliament resumes on August 26.
