Mr President, I ask a further supplementary question. What will be the impact on the budget bottom line of increases in state royalties on iron ore and coal in Western Australia, New South Wales, South Australia and Tasmania since the May budget? And why has the government also refused to release the estimated budget costs over the forward estimates for each of the measures attached to the mining tax, again in clear defiance of an order passed by the Senate? Is it because the cost of the measures attached to the mining tax is higher than the revenue it will generate from 2013-14 onwards? Again, what has the government got to hide?
