Mr President, I ask a second supplementary question. Whatever the excuse for the non-release of mining tax revenue assumptions, why has the govern­ment refused to respond to repeated requests for the costings of all the measures Labor has attached to the mining tax over the current forward estimates? Is it because this would expose the fact, in black and white, that Labor's mining tax package leaves the budget worse off to the tune of billions and billions of dollars over the forward estimates? Again, what have you got to hide?
