Senator WONG (South Australia—Minister for Finance and Deregulation) (14:39): In terms of some of these questions—and that was a collective question, I think, not an individual one—I suspect the answer would be that we will not have this information until mining companies lodge a return at the end of the income year. Senator Cormann interjecting— Senator WONG: Senator Cormann, I am very pleased to be lectured about what we should and should not be doing, but all I can say to you is that if there is any other information I can assist the Senate with I will endeavour to find it. But I suspect the advice will be that information about depreciation collectively across the mining industry, if it were to be available, would not be available until the end of the income year.
