My question is to the Treasurer. I refer the Treasurer to the statement that Don Argus, former head of the resource minister's own Policy Transition Group on the mining tax, did actually make. I quote:

You … don't want to start double-taxing the resources companies … As it is, people are looking at the sovereign risk and starting to wonder what's going on.

Will the Treasurer address growing uncertainty in the mining sector by ruling out a further redesign of the mining tax?
