Senator WONG (South Australia—Minister for Foreign Affairs and Leader of the Government in the Senate) (14:34): Thank you for placing that on the record. I wasn't aware of the Defence official's comments, and I'm grateful they are consistent with what I have said. In relation to your proposition, I will take on board your proposal and refer it to the Minister for Defence. I would also say to you, if that is a commitment that is being sought, there are obviously other ways in which that commitment can be given in the chamber, but that's a matter that would need to be negotiated with the Minister for Defence. I'll undertake to ensure that he is aware of your interest in this matter. The PRESIDENT: Senator Thorpe, second supplementary?
