Senator ABETZ (Tasmania—Leader of the Opposition in the Senate) (14:00): My question is to the Minister for Finance and Deregulation, Senator Wong. I refer to the government's decision to link its post-2015 carbon price to the European carbon price and to the minister's repeated defence of that decision in the Senate. Given that the European carbon price currently is less than $4 per tonne, does the minister have any advice that the European price is likely to increase to the $29 a tonne by 2016 that she so consistently, confidently and arrogantly predicted and, if so, what is the basis of that advice?
