Mr MORRISON (Cook—Treasurer) (14:39): The shadow Treasurer would be well aware of the process for putting together budgets. He was once a Treasurer, though it wasn't for very long. We on this side of the House are going to work very hard to ensure he doesn't get that opportunity again, because of the lack of understanding that he is demonstrating in this place about how budgets are put together. I have made it very clear that the cost of that measure over the medium term is $140 billion. You have the opportunity to support tax relief for Australians or walk away. You want to take any excuse not to support tax relief, and you'll take it, shadow Treasurer. The shadow Treasurer wants a blank cheque on tax for one simple reason. The shadow Treasurer can't stand up to the Leader of the Opposition, he can't stand up to the Deputy Leader of the Opposition, he can't stand up to the whole mob here who want to spend money like there's no tomorrow. He wants a blank cheque on tax and the Australian people should never give it to him. Mr Bowen: I want to know the cost! Mr MORRISON: He says, 'What about the cost?' Don't forget: it's their money. It doesn't cost us; it costs them to pay tax. We think they should keep what they earn. You want to take it all, through you, Mr Speaker. That's what he wants to do—$220 billion of higher taxes on the economy, and he's just getting started.
