Estimates are updated by agencies, in consultation with the Department of Finance, three times per year:
- in October as the basis for the preparation of the Mid-year Economic and Fiscal Outlook
- in early February, to provide the Government with up to date estimates prior to the budget deliberations of the Expenditure Review Committee
- in April as the basis for the preparation of the annual Budget.
The Department of Finance consolidates agencies’ estimates to construct the estimates for the Australian Government general government sector.
