But if we could talk about the details, I was actually shocked when I first heard that the costs greatly outweigh the benefits, as this proposal is estimated to cost $1 billion—$1 billion—and for every $1 spent, we will see only 11c—11c—worth of benefit. I know maths may not be the stronghold of some members, and I just want to say if Opposition members have invested in a house that is worth $1 million, if you put this mathematics—and this is cost-benefit analysis. If you spend $1 and you'll only get 11c worth left—if they bought a house for $1 million and they decide to sell it, with this 11c worth of benefit, the house will only be worth $110,000. What kind of an idiot would make that kind of an investment—that only 11c is gained as a result of spending $1. A billion dollars is the cost to the taxpayer.
