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.
