Senator BIRMINGHAM (South Australia—Minister for Finance, Leader of the Government in the Senate and Vice-President of the Executive Council) (15:20): Senator Patrick, through the chair, I don't have specifics in relation to that question. I appreciate that you're asking about one particular question, but I've not been able to get a specific update. I draw your attention to the broader points that I made before, albeit in relation to a much more general question from Senator Ayres. But I respect that you are asking about one particular question, and I will follow that up upon leaving the chamber.
