Mr ABBOTT (Warringah—Leader of the Opposition) (14:22): My question is again to the Acting Prime Minister. I refer him to electricity price increases on 1 July of up to 20 per cent in New South Wales, 18 per cent in South Australia and 15 per cent in Victoria, due in large part to the carbon tax starting at $23 a tonne. What will the electricity price increase be when the carbon tax is $350 a tonne, which is that e government's predicted carbon price by 2050?
