Senator WONG (South Australia—Minister for Finance and Deregulation) (15:01): Let us be clear what is being put in that question. What is being put in that question is: 'Because it is hard for the globe to avoid more than a two-degree temperature rise, somehow Australia should walk away from action on climate change.' That is what is being put. What is being put is: 'Because this is really hard, we should just not do anything.' That is the proposition of the opposition. Paradoxically, they pretend that they actually do want to do something, because they have signed up to a five per cent target, a target that under their policy would be achieved at double the economic cost to the Australian community. Senator Brandis: Mr President, I rise on a point of order. I draw your attention to standing order 73(4): In answering a question, a senator shall not debate it. Plainly the minister is debating the question. The PRESIDENT: There is no point of order. The minister has 19 seconds remaining. Senator WONG: I am responding to what is at the core of that question, which is the proposition that, because avoiding dangerous climate change is hard, therefore we should not do anything about it. That is essentially what is being put by the opposition. It is a ludicrous proposition, one even John Howard did not agree with. (Time expired) Senator Chris Evans: Mr President, I ask that further questions be placed on the Notice Paper.
