Mr TRUSS ( Wide Bay — Leader of The Nationals ) ( 14:26 ): My question is to the Prime Minister. I remind the Prime Minister that the chairman of the world's largest aluminium producer has stated that, 'Queensland Alumina will be the highest taxed industry in the country and that is a significant impact on our operations.' When will the Prime Minister admit that the carbon tax would shut down Queensland Alumina in places like Gladstone, as the government's own modelling confirms?
