Senator WONG (South Australia—Minister for Foreign Affairs and Leader of the Government in the Senate) (14:48): I think the senator would know that nobody has told him there's a rule against him asking questions, because he regularly asks them. In relation to the F-35, as the defence minister has said, we are one of 20 like-minded countries who operate the aircraft. We are a longstanding participant in the program, and the arrangements in relation to this program were gone through in detail on many occasions, both in here and in estimates. The PRESIDENT: Senator Shoebridge, second supplementary?
