Senator WONG (South Australia—Minister for Finance and Deregulation) (14:58): I do not think that is a serious question. It really is not a serious question. I am happy in this place to answer questions of policy. That is a piece of political diatribe. There is nothing further. Senator Brandis: Mr President, on a point of order: if the minister wants to take a point of order she is at liberty to do so. She has not done so. It is no answer to a question for the minister, in a condescending way, to say, 'That is not a serious question.' The questioner is entitled to an answer, and if she wants to challenge it there is a way to do so. The PRESIDENT: There is no point of order. Minister, have you anything further to answer? Senator WONG: A little irony to be accused of being condescending by Senator Brandis. He is good at that. Senator Sherry: QC. Senator WONG: I am sorry, Senator Brandis QC, aka Lord Brandis. I have outlined the reasons for the government's intent to price carbon, I have explained the reasons for it and I have nothing further to add to my previous answer.
