This compendium examines Australia’s counterterrorism trajectory from the immediate post-9/11 period to a more complex contemporary threat environment. Drawing on articles originally published in The Strategist, the collection explores domestic and international terrorism, radicalisation, antisemitism, lone actor violence, youth extremism, and the growing intersection between terrorism, technology and statecraft.

The report critically examines Australia’s counterterrorism architecture, including leadership, legislation and inter-agency coordination. It highlights the importance of public trust, community resilience and clear government leadership as essential national security enablers and reflects on recent events that have tested Australia’s preparedness, questioning whether existing frameworks remain fit for purpose.

It is intended for policymakers, security professionals, researchers and students seeking analysis of the challenges shaping Australia’s counterterrorism future and the policy choices required to meet them.
