Senator BIRMINGHAM (South Australia—Minister for Finance, Leader of the Government in the Senate and Vice-President of the Executive Council) (14:59): I refer to the correction to the record I just gave to Senator O'Neill. If there's any information around dates of knowledge, or the like, I'll seek to bring that to the House. The PRESIDENT: Senator O'Neill, a second supplementary question? Senator O'Neill: I'm sorry, Mr President, I actually couldn't hear Senator Birmingham's response. I was listening. I simply couldn't hear his response. The PRESIDENT: I don't want to put words into the minister's mouth, but I believe he took it on notice—if he could get you further information. Senator O'Neill, a second supplementary question?
