Senator BIRMINGHAM (South Australia—Minister for Finance, Vice-President of the Executive Council and Leader of the Government in the Senate) (15:19): I thank Senator Rice. That didn't necessarily concur with my understanding, but it was only quite late into question time that I, at least, received information about your intent to query this matter. I don't have the details to provide to the senator at present. But I will seek to find an explanation and the answer to that question from the relevant department and provide it to the chamber at a later time.
