Senator WONG (South Australia—Minister for Foreign Affairs and Leader of the Government in the Senate) (14:25): I am interested to see Senator Shoebridge effectively parroting the same attack that the coalition made about this. The Greens-coalition alliance is going well. There are two things I would say to you. One is that we care about the safety of the nation, Senator Shoebridge. Would you like— Senator Shoebridge interjecting— The PRESIDENT: Order! Senator Shoebridge, you are out of order. Senator WONG: We've made the decision in relation to nuclear powered submarines because of circumstances Australia faces and because national security comes first. Secondly, in relation to nuclear power, as you know, the coalition's plan would deliver the most expensive power in the world in a number of decades time. It does not make economic sense even before we get to the waste issue.
