Senator FARRELL (South Australia—Minister for Trade and Tourism, Special Minister of State and Deputy Leader of the Government in the Senate) (14:19): I thank Senator Cox for her first supplementary question. There is a difference between mining uranium and the proliferation of nuclear weapons but, as you say, this issue was discussed at the recent ALP national conference, at which I was present. Labor has a proud history of advocating for nonproliferation and disarmament and is committed to the goal of a world without nuclear weapons. We support the treaty— The PRESIDENT: Minister Farrell, please resume your seat. Senator Cox? Senator Cox: Just a point on relevance. My direct question went to a time line, so, with the last 16 seconds, can you point the minister in the direction of the time line, please? The PRESIDENT: I believe he is being relevant. Minister Wong? Senator Wong: I apologise to Senator Cox and the President, because I was just distracted, but I would raise again that it doesn't sound to me like this is a supplementary question from the original question. In fact, the treaty—TPNW—is probably better addressed to my portfolio, not the resources portfolio, and a number of others have raised it. Certainly I don't recall the treaty being discussed in the primary question. Obviously, the minister can answer what he's able to in his portfolio, but I again request that we look at whether or not supplementary questions are in fact supplementary. The PRESIDENT: Senator Cox, I have sought advice, and the clerk has advised me that you have jumped portfolio. As Minister Wong has informed you, Senator Farrell will continue to answer the question, but—yes, Senator Cox? Senator Cox: Can I clarify that the words 'treaty on the prohibition of nuclear weapons' was actually in the original question? But I appreciate Senator Wong's— T he PRESIDENT: Yes. I noted the word was there, but I'm nevertheless advise that you have jumped portfolios. Senator Farrell. Senator FARRELL: The government is engaging constructively to identify realistic pathways for nuclear disarmament. For this reason— (Time expired) The PRESIDENT: Senator Cox, second supplementary?
