Senator BOB BROWN (Tasmania—Leader of the Australian Greens) (14:20): My question is to the Minister representing the Treasurer. In relation to the proposed tax forum, will the government review the Treasury proposal for a mining super profits tax, particularly in view of the BlueScope Steel decision to stand down 1,000 workers, the two-speed economy and BlueScope's observation that it is the mining resources boom that has caused these difficulties, which are likely to spread to the rest of the manufacturing sector?
