The objective of the preliminary study was to form a view regarding the quality of, and controls over, the Budget estimates and to inform the decision whether to proceed to a full performance audit at this time. On the basis of the quantitative and qualitative analysis of the budget process undertaken during the study, the ANAO concluded that there are no apparent systemic problems in the cash-based estimating processes in the agencies reviewed that would, in themselves, lead to material statistical inaccuracies in the Budget's projected outcomes. The ANAO decided not to proceed with a full performance audit at this time.
