Senator WONG (South Australia—Minister for Finance and Deregulation) (14:38): I think both— Senator BOSWELL: Mr President, on a point of order: I refer to Senator Brown's position that it was a 'whopping lie'; is that parliamentary? I think you should call it— The PRESIDENT: It is all right, Senator Boswell. The question stands. Senator WONG: Rather than getting into a debate about what may or may not be in a particular advertisement, I will just make this point. The proposition that there is no point in pointing in place a carbon price has been made endlessly in this place by Senator Joyce and others. I am on record over quite a number of hours and days in the context of previous climate change debates answering that. It is an interesting proposition because what it essentially says is, 'We might think climate change is real, but everyone else should fix it.' If you say that we do not need to do anything in Australia, you are essentially saying that this might be a problem but other people have to deal with it. (Time expired)
