Mr MORRISON (Cook—Treasurer) (14:19): I thank the Prime Minister for the opportunity to respond, because both of us know full well every single measure that is in the budget, because this is our national economic plan for jobs and growth. But as the Prime Minister has rightly said, it has been the longstanding practice of governments of all persuasions to produce the estimates over the budget and forward estimates, and you will find within this document a more— Ms Butler: Mr Speaker, a point of order: the state of the knowledge of the Prime Minister is a matter within his own knowledge exclusively. The minister is not able to answer the question. The SPEAKER: The member for Griffith has no point of order. The member for Griffith has already been warned. The Treasurer has the call. Ms Plibersek interjecting— The SPEAKER: The member for Sydney is warned! Mr MORRISON: I know those opposite are looking for taxes. I know they are looking for some revenue to find to fill the hole in the Leader of the Opposition's speech tonight, but they need to understand how budgets are put together. They will find on page 25 the full summary of costings of all the revenue measures that are contained in the budget over four years. Mr Dreyfus interjecting— The SPEAKER: The member for Isaacs is warned! Mr MORRISON: They may have forgotten, but I refer them to the comments of the then finance minister, Penny Wong, on 18 March 2012. In relation to these sorts of questions, when they are put, 'What is the 10-year cost?' of the particular item, she said, 'We don't release 10-year costings.' That was the policy of their government. It has been the policy of pretty much every government. So we follow the practice put in place by those opposite. If they go to Budget Paper No. 1, page 3-11, they will find the underlying cash balance predicted to 2026-27 and they will know, if they have had an involvement with the budget before, that what happens is you take the individual measures and you combine them all together and you look at what the long- and the medium-term projection is over 10 years to 2026-27. What that document means is that our Ten Year Enterprise Tax Plan ensures that, on projections, we move to a position of budget balance in 2021 and we stay there until 2026-27. That includes our Ten Year Enterprise Tax Plan. So every measure across the medium term, across the short term in the budget and forward estimates is affordable, and the way we have done it is we have not spent more than we have saved and we have not taxed more and increased the tax burden over previous projections. But, from those opposite, every time you see the Leader of the Opposition's lips moving tonight, he will be spending more money, which means only one thing—he is going to be taxing you harder and harder and harder.
