Australian Cyber Security Centre
Australian Government lead agency for cybersecurity
The Australian Cyber Security Centre (ACSC), the successor to the Cyber Security Operations Centre, is the Australian Government's lead agency for cyber security. The ACSC is part of the Australian Signals Directorate and is based at the Australian Security Intelligence Organisation headquarters in Brindabella Business Park in Canberra. The centre is overseen by the Cyber Security Operations Board and is the joint responsibility of the Minister for Defence.
History
The Australian Cyber Security Centre was established in 2014, replacing the Cyber Security Operations Centre, also housed by the Australian Signals Directorate. In line with the recommendations of the 2017 Independent Review of the Australian Intelligence Community led by Michael L'Estrange and Stephen Merchant, Prime Minister Malcolm Turnbull announced that the role of the Australian Cyber Security Centre would be strengthened and that the Prime Minister's Special Adviser on Cyber Security, Alastair MacGibbon, would assume the responsibilities as the Head of the Centre within the Australian Signals Directorate, which was established as a statutory agency. The Special Adviser position was removed when MacGibbon left the public service in May 2019.
Role and responsibilities
The role of the Australian Cyber Security Centre is to:
lead the Australian Government's operational response to cyber security incidents
organise national cyber security operations and resources
encourage and receive reporting of cyber attacks and cyber security incidents
raise awareness of the level of cyber threats to Australia
study and investigate cyber threats
The ACSC integrates the national security cyber capabilities across the Australian Signals Directorate cyber security mission, cyber security experts from the Digital Transformation Agency, the Defence Intelligence Organisation strategic intelligence analysts, the Computer Emergency Response Team, the Cyber Security Policy Division of the Department of Home Affairs, Australian Security Intelligence Organisation cyber and telecommunications specialists, Australian Federal Police cyber crime investigators, and Australian Criminal Intelligence Commission cybercrime threat intelligence specialists. The centre is also a hub for collaboration and information sharing with the private sector and critical infrastructure providers, state and territory governments, academia and international partners.
Governance
The Head of the Australian Cyber Security Centre is a concurrent Deputy Director-General of the Australian Signals Directorate. The Special Adviser to the Prime Minister on Cyber Security within the Department of the Prime Minister and Cabinet previously served concurrently as the Head of the centre.
This brief starts where responsible research should: with the source description of “Australian Cyber Security Centre” as australian Government lead agency for cybersecurity. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the history & society register because the source frames it as australian Government lead agency for cybersecurity. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Aug 8, 2026. The linked authority identifier is Q20113801. 1 of 2 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank. The first chronological checks are 2014, 2017 and 2019.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
