Senator ABETZ (Tasmania—Leader of the Opposition in the Senate) (14:03): Mr President, I ask a supplementary question. Does the minister acknowledge that she and the government were repeatedly warned about the dangers of linking Australia's carbon price to the European price? And will she apologise to the Senate and the Australian people for the head-in-the-sand 'we know best' attitude that she and her ministerial colleagues took to those who warned about those dangers?
