The Prime Minister is under increasing pressure to release what advice the $10.4 billion financial package is based on.
On Tuesday the opposition declared bipartisan support for the package, aimed at protecting the economy from the global financial crisis, but are now attacking it.
Opposition Treasury spokeswoman Julie Bishop's told ABC television, the Australian people have a right to know why the government's taking such dramatic action.
“We would have expected the government to tell the Australian people, through the parliament, that growth is expected to slow to a particular per cent.
“Now, it took us three questions to get the Prime Minister to say ‘there will be a two in front of it’.”
She says it's the opposition's role to hold the government to account, but says it seems outraged they would dare question the evidence upon which this package is based.
Ms Bishop was referring to a fiery question time in parliament yesterday, when the opposition tried to ascertain what economic advice the government had received on the economy.
