The Australian Cyber Security Centre is the Australian Government’s lead on national cyber security. It brings together cyber security capabilities from across the Australian Government to improve the cyber resilience of the Australian community and support the economic and social prosperity of Australia in the digital age.

In July 2018 the ACSC became part of the Australian Signals Directorate (ASD), which became a statutory agency. Australian Government cyber security expertise from CERT Australia and the Digital Transformation Agency moved into the ACSC.

These changes are part of the government's national security reform package to enhance the cyber security support and services the government provides to industry, government and the community.

The ACSC began operations in 2014. Since then, and as part of the Independent Intelligence Review in 2017, the Australian Government identified the need to provide enhanced cyber security capabilities and a single point of advice and support on cyber security. On 1 July 2018, the agency expanded and formally became part of the Australian Signals Directorate (ASD).
The ACSC includes staff from the:
Australian Criminal Intelligence Commission
Australian Federal Police
Australian Security Intelligence Organisation
Defence Intelligence Organisation
Department of Home Affairs Cyber Security Policy Division staff are collocated with ACSC staff to better inform policy advice for government.

The ACSC is based in Canberra but has offices throughout the country as part of the Joint Cyber Security Centre program.
