Senator FARRELL (South Australia—Minister for Trade and Tourism, Special Minister of State and Deputy Leader of the Government in the Senate) (14:57): I thank Senator Rennick for his question. It's pleasing to see that somebody in this place has got an interest in science and industry. That's a very pleasing development. I don't know the specifics of your question off the top of my head because, of course, this is not my policy area. We have a very fine minister in Minister Husic, who looks after this area, and I will get an answer to your question from him as soon as I can. But can I say this: I don't think the science is in dispute about the need to move to net zero, Senator Rennick. Australia is unique— The PRESIDENT: Minister Farrell, please resume your seat. Senator Rennick? Senator Rennick: Point of order: the question is how it's being measured, not whether or not it's in dispute. It's about how it's being measured and the accuracy and quality assurance of those measurements. The PRESIDENT: There was an introduction to your question. I think the minister is being relevant to the question, and I will continue to listen carefully. Thank you, Senator Rennick. Minister Farrell. Senator FARRELL: Thank you for that support for my answer. I said to you quite honestly, Senator Rennick, that I don't have the specific details to answer that question, but I will get them for you. But I'm making the general point that the need to move to net zero is not in dispute. This country is uniquely placed not only to move to net zero for our own economy but to assist the rest of the world to do so. One of the areas that I'm very directly involved in is the issue of critical minerals. Australia is very fortunate in that we have an overabundance of those critical minerals that we're going to need to move to net zero. (Time expired) The PRESIDENT: Senator Rennick, first supplementary?
