Senator BRANDIS (Queensland—Attorney-General, Vice-President of the Executive Council and Leader of the Government in the Senate) (14:13): Senator Dastyari, you begin with a very important and valuable question, and unfortunately you follow it up with a foolish, undergraduate question, as if a comment by Senator Hanson on one issue—which I regret and the Prime Minister regrets—amounts to the entirety of One Nation's contribution to Australian politics or to this chamber. I entirely agree with what Senator Sinodinos has had to say and have had similar things to say myself. In terms of its contribution in this chamber, Senator Dastyari, I am bound to say Senator Hanson and her colleagues have made a more sophisticated contribution than the level of sophistication evident in your supplementary question. The PRESIDENT: Senator Dastyari, a final supplementary question.
