The Australian Government announced on 1 December 2009 that Commonwealth security vetting processes would be centralised in the Department of Defence. This central vetting unit, known as the Australian Government Security Vetting Agency (AGSVA), will conduct security vetting for all Commonwealth agencies (apart from exempt agencies). Clearances granted by AGSVA have whole-of-government effect.

Implementation of the AGSVA has been part of a Better Regulation Ministerial Partnership initiative between the Attorney-General, the Minister for Finance and Deregulation and the Minister for Defence to reduce costs and improve the efficiency of the security vetting process.

As part of this initiative, the Australian Security Vetting Service (ASVS) has transferred from the Attorney-General’s Department to the Department of Defence under a Machinery of Government Change.

The AGSVA is situated within the Defence Security Authority, and employs over 200 staff located in all major capital cities around Australia.
