Mrs MIRABELLA (Indi) (14:23): My question is to the Prime Minister. Is the finance minister right when she says the member for Griffith's suggestion of a review of the carbon tax could have a very negative effect, or is the resources minister right when he says: … there is a lot of concern in industry at the moment about the price we've locked in … whether we've locked in a price that's to our disadvantage as a nation.
