Senator BRANDIS (Queensland—Attorney-General, Vice-President of the Executive Council and Leader of the Government in the Senate) (14:02): I am surprised to hear, Senator Gallagher, that Senator Back feels the need for enlightenment, because I find Senator Back to be one of the most enlightened people I have ever had the pleasure of dealing with in this parliament. Senator Back, who, as all of his colleagues know, is both a gentleman and a scholar, needs no enlightenment about anything because he is such an enlightened gentleman. Now, in relation to the question of negative gearing, what we know, Senator Gallagher, is that under a policy announced by your leader, Mr Bill Shorten, the value of people's homes— The PRESIDENT: Pause the clock. Senator Wong: Mr President, I raise a point of order in relation to direct relevance. There was only one question: when will the Prime Minister come clean and tell his own backbench and the parliament about his tax plans? The PRESIDENT: Thank you, Senator Wong. I remind the minister of the question. Senator BRANDIS: On the point of order—I am sorry; I cannot address the point of order. Mr President, you have ruled on the point of order. Senator Wong interjecting— Senator BRANDIS: Senator Gallagher—through you, Mr President— Senator Wong interjecting— Senator BRANDIS: If you wouldn't mind ceasing interjecting, Senator Wong, please. Opposition senators interjecting— The PRESIDENT: Order, on my left! Senator BRANDIS: There is one thing we know about the negative-gearing debate. What we know about the negative-gearing debate is that, if the Labor Party were to implement its policy, the value of most Australians' homes would collapse. (Time expired)
