Senator WONG (South Australia—Minister for Finance and Deregulation) (14:32): I love the way the tactics committee sees the word 'modelling' somewhere and then decides they want to talk only about modelling for the entirety of question time. It is a pity the senator did not listen to my response to Senator Bernardi, wherein I pointed out that the Treasurer had flagged the release of this modelling this week. I am not sure how the senator comes to suggest that there has been a leak. Some aspects of it, and the fact of it, were released in the Treasurer's economic note. That is hardly a leak. The coalition cannot come into this chamber pretending to actually care about the economic costs of action on climate change when its own policy has been so poorly costed and will lead to a doubling of the economic cost of achieving the five per cent target. But you do not have to believe me. It is what the Treasury says. It is what the Business Council of Australia has referenced. The PRESIDENT: I draw the minister's attention to the question. Senator WONG: The question goes to the modelling and the economic cost. Those on the other side, if they are interested in the economic cost, should perhaps look at some of their own policies. Again, I refer the good senator to the note released by the Treasurer. He made reference to the fact that the modelling will be released this week, as previous modelling has been—unlike anything on the opposition's side when it comes to both the economic and the fiscal cost of this policy.
