Senator CANAVAN (Queensland—Minister for Resources and Northern Australia) (14:13): Again, not to my knowledge. The PRESIDENT: Senator Wong? Senator Wong: Mr President, that's the second occasion on which the minister is saying he doesn't know. We'd like him to take it on notice. Well, we think this matter goes to a matter of— Senator Seselja: You don't get to direct him; you can do it in the supplementary. Senator Wong: Well, I'm asking that and, if he refuses, that will be plain. Government senators interjecting— The PRESIDENT: Order on my right! Can I hear Senator Wong? Can I hear Senator Wong before I rule? Senator Wong. Senator Wong: I'm requesting that the minister take it on notice. The PRESIDENT: Okay. Senator Wong, that is not a point—Senator Cormann? Senator Cormann: I just on the point of order make the point that the question was asked and the minister answered the question. The minister answered the question as he was able to answer it, so there's no point of order. Opposition senators interjecting— The PRESIDENT: Order on my left! I asked for order on my right. Senator Collins, please resume your seat. On my left: I asked for order on my right so I could hear Senator Wong. I'm going to ask you to return the courtesy to Senator Cormann. Senator Collins, I'm prepared to rule on this. Senator Wong did not raise a point order. I cannot instruct the minister how to answer the question. There is an opportunity in this chamber to ask questions. The minister was relevant to the question. That is the limit of my authority. Senator Cameron, do you have a final supplementary question?
