It is instructive in understanding the imprest supply element of the motion today to look at the Supplementary Estimates, because they give a good indication of the kind of expenditure that a Government might require in a given year, and in the Supplementary Estimates that were assessed by the select committee, we can see good examples of the way in which the Government is required from time to time to do things that are either unexpected or unbudgeted for—for example, sometimes these are small elements of much larger appropriations. One example in this year's Supplementary Estimates is in the corrections area, where there were significant changes required partly because of costs that were being incurred by the Department of Corrections when they were undertaking their capital works and revaluing land and building assets. These are reasonably normal occurrences that occur in each year and are accounted for in this bill.
