APS Agencies – size and function

This page lists all entities that have staff employed under the Public Service Act 1999. Agencies are grouped according to their size (APS headcount) as reported for the APS Employee Database as at 30 June 2026.

For more information about agency sizes, see – APS Employment Data Release | Australian Public Service Commission

Agencies are also grouped by ‘functional clusters’ to allow comparisons to be made between agencies with similar primary functions. The six functional clusters applied to APS agencies are as follows:

• Policy: agencies involved in the development of public policy.
• Smaller operational: agencies with less than 1,000 employees involved in the implementation of public policy.
• Larger operational: agencies with 1,000 employees or more involved in the implementation of public policy.
• Regulatory: agencies involved in regulation and inspection.
• Specialist: agencies providing specialist support to government.
• National cultural institutions: agencies that maintain collections of material and offer public programs relevant to Australia’s cultural heritage.
