Federal Budget (Australia)

An Australian federal budget is a document that sets out the estimated revenues and expenditures of the Australian Treasury in the following financial year, proposed conduct of Australian government operations in that period, and its fiscal policy for the forward years. Budgets are called by the year in which they are presented to Parliament and relate to a financial year that commences on the following 1 July and ends on 30 June of the following year, so that the 2016 budget brought down in May 2016 relates to the 2016/17 financial year (1 July 2016 – 30 June 2017, FY2017).

Revenue estimates detailed in the budget are raised through the Australian taxation system, with government spending (including transfers to the states) representing a sizeable proportion of the overall economy. Besides presenting the government's expected revenues and expenditures, the federal budget is also a political statement of the government's intentions and priorities, and has profound macroeconomic implications.

Australia follows, to a great extent, the conventions of the Westminster system. For example, the prime minister must have the support of a majority in the House of Representatives, and must in any case be able to ensure the existence of no absolute majority against the government. In relation to the budget, that requires that if the House fails to pass the government's budget, even by one dollar, then the government must either resign so that a different government can be appointed or seek a parliamentary dissolution so that new general elections may be held in order to re-confirm or deny the government's mandate.

The process of putting together the budget begins in November when the accrual information management system (AIMS) is updated with the latest estimates, and the senior ministers' review, where the Prime Minister, Treasurer, and Minister for Finance meet to establish the policy priorities and strategy for the coming financial year.
