Senator WONG (South Australia—Minister for Foreign Affairs and Leader of the Government in the Senate) (14:51): Well, I'm asked for an opinion, and I probably won't proffer that, but I can make an observation, which I think I've made before in estimates. Obviously, when you're looking at defence capability a number of matters need to be considered: the capability, the value for money for taxpayers and also assuring a sovereign capability for Australia in those areas where that is necessary for our national security. That is the approach the government seeks to take.
