Senator JOHNSTON (Western Australia—Minister for Defence) (14:40): I am glad you have raised my Liberal colleagues from South Australia, because they have been most supportive and helpful in taking this program forward in a sensible and proper way. They understand and have been talking to me about the need to progress submarines in Australia. You and all of your South Australian senators just sat there for six years doing nothing. My colleagues are saying— Opposition senators interjecting— The PRESIDENT: Order! I just want to point out that all remarks both with the question and certainly with the answer must be directed to the chair, not across the chamber. Senator JOHNSTON: My colleagues have been extremely supportive of the action we have undertaken, given that we are starting from zero. We are starting from zero—and, of course, you never ask the right questions. Submarines are a hot topic; how many submarines questions were asked at estimates last Wednesday? I think you will find very close to a round number before one! That is how concerned you people are over there.
