Mr TRUSS (Wide Bay—Leader of The Nationals) (14:53): My question is to the Treasurer. I remind the Treasurer that the average European carbon price forecast for 2016 is currently less than $10.50 a tonne. Given that the government is budgeting to raise $9.4 billion just from the sale of permits that year, based on a price of $29 a tonne, will the Treasury rule out increasing taxes on superannuation to make up the shortfall?
