Senator GALLAGHER (Australian Capital Territory—Minister for the Public Service, Minister for Finance, Minister for Women, Manager of Government Business in the Senate and Vice-President of the Executive Council) (14:39): I think it's probably best that I take that question on notice, because I wasn't a member of the government that entered into the arrangement. I'm not trying to not take responsibility, but I think it's probably best that I get an answer to you after taking some advice about that. I know there were elements of the contract that weren't public, and I don't know if there are some commercial-in-confidence arrangements in place, but I will seek to update the Senate with what information I can find, in an attempt to answer your question, Senator Roberts. The PRESIDENT: Senator Roberts, a second supplementary?
