Note: Information in this database has been derived from sources reliable and accurate at the time of last update (February 2023). Readers should note that circumstances may change after a document is published, including as a consequence of changes to government policy or industry practice resulting from a document’s publication. The information is provided on the basis that readers are responsible for making their own assessment of the matters contained or discussed on this site.

This database makes available much of the data relating to the defence budget and defence spending that ASPI has accumulated since it was established in 2001. It aims to help researchers and organisations to develop their own analysis and visualisations of the defence portfolio.

The Cost of Defence Public Database

The database amalgamates historical data from a broad range of sources including:

• Department of Defence portfolio budget statements (PBS) and portfolio additional estimates statements (PAES)
• Department of Defence annual reports
• Defence policy documents such as white papers and strategic updates
• Australian government budget papers
• Australian National Audit Office reports, in particular the annual Major Projects Report

The data is presented in Microsoft Excel files which are available for download. Some pre-made charts and graphics have also been generated as supplementary material.

Much of this data is presented and analysed in ASPI’s annual The Cost of Defence budget brief. You can read this year’s The Cost of Defence report here.

ASPI will update the data at key milestone during the year, such as publication of the PBS (usually May), PAES (January) and Defence annual report (October).

The following categories of data are available for download:

• Defence funding
• The Capital Program
• The Sustainment Program
• Personnel
• Flying Hours and Costs
• The Cost of Operations
• Defence Cooperation Program
• Shipbuilding
