Senator GALLAGHER (Australian Capital Territory—Minister for the Public Service, Minister for Finance, Minister for Women, Manager of Government Business in the Senate and Vice-President of the Executive Council) (14:57): I thank Senator Hughes for the question. I would ask: How many nuclear reactors are going to be required, and what is the percentage of nuclear energy on the grid? What is it? We heard there are lots of them. How many? You couldn't answer. Senator Hughes: Point of order on relevance. It's not a question about anything other than the replacement by 2050. I'll give you a tip: it's 100 per cent. The PRESIDENT: Senator Hughes, resume your seat. Senator Hughes, you rose on a point of order. I reminded you the last time you rose on a point of order not to go beyond the point of order, and you did it again. I will draw the minister to your question. Senator GALLAGHER: I guess it is a reasonable thing, when you release a nuclear reactor plan, to be able to say how many nuclear reactors you're going to need. What we saw on Sunday is that not only have seven sites been identified but on those sites they could have multiple reactors. Maybe you could have four. Maybe you could have five. Who knows? You don't know yet. Honourable senators interjecting— The PRESIDENT: Minister Gallagher, please resume your seat. Senator Hughes: Point of order on relevance. The PRESIDENT: Senator Hughes, I haven't called you. The reason I haven't called you is that I am waiting for order in the chamber, and then I'll call you. Senator Hughes. Senator Hughes: The question did not use the word nuclear, yet the minister's barely said anything but. The PRESIDENT: Thank you, Senator Hughes. I will remind the minister of your question. Senator GALLAGHER: We back renewables. We back solar. We back wind. We back the turbines. We back the panels. And we will continue to, and we will need firming fuel. What we won't do is come out with a half-baked plan. It's not even half-baked. It's a miniscule-baked plan that delivers no idea on cost, size, or when it would actually deliver the energy or anything else. (Time expired) The PRESIDENT: Senator Hughes, a second supplementary?
