Senator BRANDIS (Queensland—Attorney-General, Vice-President of the Executive Council and Leader of the Government in the Senate) (14:41): Senator Ketter, I don't know what Senator O'Sullivan's arrangements are and who he speaks to. Senator O'Sullivan is a very industrious senator and he speaks to many colleagues. But, Senator Ketter, you asked about a commission of inquiry. I've explained to you why—in redressing the problem that the government, like the opposition, acknowledges is a matter of legitimate public concern—a royal commission is not the best mechanism or vehicle to deal with that problem. The PRESIDENT: A final supplementary question, Senator Ketter.
