Senator WONG (South Australia—Minister for Finance and Deregulation) (14:13): To make it clear, confidential costings are available outside of the election period; it is only in the election period that costings must be publicly released. I would ask the coalition to consider the words of Mr Costello: By requiring the costings to be made publicly available, there is limited scope for the results of the costings to be misrepresented. So the reason Mr Hockey wants to hide from scrutiny is this. He came up with a $70 billion black hole. He knows he has a $70 billion black hole. At first he tried to walk away from it by saying, 'Actually, oops, I didn't say that,' but Mr Robb has come up with a new tactic: 'Let's hide it from the Australian people. Let's never have to front up to the Australian people'—as they had to after the last election—'and show them how we are going to fill the $70 billion black hole.' This is just more fiscal irresponsibility from Mr Hockey. (Time expired)
