Mr COULTON (Parkes—The Nationals Chief Whip) (14:09): My question is to the Deputy Prime Minister and Minister for Infrastructure and Regional Development. I refer to the list of liable entities, released by the Clean Energy Regulator on Friday, 20 June, which shows that Qantas, Virgin and Rex will face a carbon tax bill of $171 million in 2013-14. What is the government doing to remove the carbon tax, and how will air travellers benefit from its removal?
