The Australian Intelligence Community (AIC) and the National Intelligence Community (NIC) or National Security Community of the Australian Government are the collectives of statutory intelligence agencies, policy departments, and other government agencies concerned with protecting and advancing the national security and national interests of the Commonwealth of Australia. The intelligence and security agencies of the Australian Government have evolved since the Second World War and the Cold War and saw transformation and expansion during the Global War on Terrorism with military deployments in Afghanistan, Iraq and against ISIS in Syria. Key international and national security issues for the Australian Intelligence Community include terrorism and violent extremism, cybersecurity, transnational crime, the rise of China, and Pacific regional security.

The National Security Committee (NSC), also known as the National Security Committee of Cabinet, is the peak decision-making body for national security and major foreign policy matters in the Australian Government. It is a committee of the Cabinet of Australia, though decisions of the NSC do not require the endorsement of the Cabinet itself.
