Senator CASH (Western Australia—Minister for Small and Family Business, Skills and Vocational Education) (14:58): Senator Watt, I would also recall that you have asked me question after question after question at a number of estimates hearings in relation to this exact matter, and I stand by the answers I've previously given. The PRESIDENT: Senator Wong? Senator Wong: I asked about knowledge, and she's refusing to answer. The PRESIDENT: There's an opportunity after question time to address ministers' answers. Once the minister has concluded her answer, I can't take a point of order on relevance. Senator Watt?
