Senator BIRMINGHAM (South Australia—Minister for Finance, Leader of the Government in the Senate and Vice-President of the Executive Council) (14:35): Senator Fierravanti-Wells is as entitled as any of the other 75 senators elected to this place to come into this chamber, to provide speeches, to give general reflections in relation to the way in which politics operate. I recognise— Opposition senators interjecting— The PRESIDENT: Order on my left! Senator BIRMINGHAM: the enormous contribution that Senator Fierravanti-Wells makes, on behalf of New South Wales, to our party and to our government in particular, and she has done so through a wide range of different roles. But I know, as well, that the model for an integrity commission we have developed is a sound model—a model that strikes the balance of ensuring that we would have an integrity commission focused on rooting out corruption, and on prosecuting where applicable, but not on show trials. I know those opposite just want show trials; they just want politics. We actually want effective reform. Opposition senators interjecting— The PRESIDENT: Order! Senator McAllister interjecting— The PRESIDENT: Senator McAllister! Senator Urquhart, a second supplementary question?
