Senator FARRELL (South Australia—Minister for Trade and Tourism, Special Minister of State and Deputy Leader of the Government in the Senate) (14:13): I thank Senator Birmingham for his first supplementary question. In respect to the chief of staff of the Prime Minister, he is on the staffing committee. I don't recall any circumstances in which the issues that you've referred to have been discussed at the staffing committee, but I'll take that question on notice and come back to you. The PRESIDENT: Senator Birmingham, second supplementary?
