Senator BIRMINGHAM (South Australia) (14:42): Mr President, I ask a supplementary question. I again ask the minister if she agrees with Mr Comley that business will pass on the costs of these international permits. I also refer the minister to statements by the Prime Minister that compensation will keep up with the rising cost of the carbon tax. How will the government fund this increased compensation to cover the billions spent by Australian companies on international permits when, as Mr Comley says, the revenue from these permits does not go into the budget in any way?
