Senator FARRELL (South Australia—Minister for Trade and Tourism, Special Minister of State and Deputy Leader of the Government in the Senate) (14:41): I thank Senator Thorpe for her question. I make the point that it's probably not supplementary to the questions that have been asked in respect of Kimba and the nuclear waste facility. The issue of treaties is not something that is in my portfolio. I have responsibility for trade and tourism and I am Special Minister of State. We are extremely fortunate in this place to have Senator Wong as our wonderful Minister for Foreign Affairs, and I shall be— The PRESIDENT: Minister Farrell, please resume your seat. Senator Thorpe: I raise a point of order on relevance. The question was: when will the government sign the treaty as promised by the government. I understand that the minister may not have that on hand, but could he seek that advice from the minister he's representing? The PRESIDENT: What the minister said at the outset, Senator Thorpe, was that this second supplementary needed to be related to the primary question and the first supplementary question. They went to low-level waste, as I understood them, and to legal costs, so I agree with the minister that the third question is not related to the other two. He has been answering it, so this is really an invitation to the minister to answer the question, because it's not a supplementary in the true meaning of a supplementary. Senator FARRELL: Thank you, President, for that clarification. I shall discuss the matter with the foreign minister after question time and I will come back to you with a formal response to the question that you've asked, even though it's not in the specific area of my portfolio.
