Senator CASH (Western Australia) (14:57): Oh! I ask a supplementary question— Senator Kim Carr: This is hilarious, is it? The PRESIDENT: Senator Cash, as is the case with every other senator who asks a question, you are entitled to be heard in silence. Those on my right will remain silent. Senator CASH: I refer to the recent testimony before Senate estimates by departmental secretary Martin Bowles, in which he made no reference to any concerns or investigations regarding abuses of the 457 program. Can the minister advise whether the department has undertaken any recent inquiries, reviews or investigations into abuses of the 457 program and, if so, when were the findings presented to the government and in what form, bearing in mind the minister's answer to my first question where she clearly alluded to this particular evidence?
