Senator JOYCE (Queensland—Leader of The Nationals in the Senate) (14:16): Mr President, I ask a supplementary question. I refer the minister to the fact that Queenslanders have had an average $700 added to their household power bills despite Labor's promise that nobody would be worse off under the Bligh government's electricity privatisation. Given that the carbon tax will increase the power bills of Queenslanders by an additional 10 per cent, can the minister explain how a big increase in electricity prices in Queensland, which is not matched anywhere else in the world, will provide any specific environmental benefit to Queenslanders apart from making them stone motherless broke?
