Senator DASTYARI (New South Wales) (14:50): My question is to the Minister for Finance, Senator Cormann. I remind the minister that, before the election, the Prime Minister denied there would be any increases in tax under a Liberal government. Given that the minister announced by ambush today an increase in the petrol tax, can the minister please explain why the Prime Minister lied to the Australian people? Senator Abetz: That has to be withdrawn. Senator Cameron: He does that all the time. The PRESIDENT: Order! Senator Cameron, please desist from interjecting. Senator Dastyari, you were referring in an unparliamentary way to the Prime Minister. If you withdraw that element I will then call upon the minister to answer the question. Senator DASTYARI: I withdraw. Can the minister please explain why the Prime Minister misled the Australian people?
