Senator JOYCE (Queensland—Leader of The Nationals in the Senate) (14:56): Mr President, I ask a supplementary question. I refer the minister to the Queensland Treasury's modelling of the impact of a carbon tax on regional Queensland, which shows that the carbon tax will reduce economic output in the areas surrounding Mackay, Rockhampton and Gladstone by double to triple the amount that the carbon tax would reduce Australia's overall output by. Does the minister agree that the carbon tax will have a disproportionate impact on regional Queensland or does she think that the Labor Treasurer is scaremongering?
