Senator IAN MACDONALD (Queensland) (14:45): Mr President, I ask a supplementary question. Minister, is the climate commission you are talking about led by a person who, two weeks before the greatest floods that ever hit Brisbane, promised there would never be another drop of rain in Queensland? Do you believe that a carbon tax that will next week be $24.15 a tonne will be beneficial to Australia when Europe, which emits about five times as much carbon, has a carbon tax of only $5.84 per tonne?
