Country
Australia
Six-agency National Intelligence Community led by the Office of National Intelligence, including the foreign HUMINT service ASIS and signals agency ASD.
Australia's National Intelligence Community comprises ten agencies, with six core services in the foreign-intelligence and security space. The Australian Secret Intelligence Service (ASIS) is the foreign human-intelligence service, the country's analogue to the US CIA or UK SIS. The Australian Security Intelligence Organisation (ASIO) is the domestic security service. The Australian Signals Directorate (ASD) is the signals-intelligence and offensive-cyber agency.
The three are joined by the Australian Geospatial-Intelligence Organisation (AGO), the Defence Intelligence Organisation (DIO), and the Office of National Intelligence (ONI), which serves as the coordinating body. Australia is a founding member of the Five Eyes signals partnership, alongside the United States, United Kingdom, Canada, and New Zealand.

How to read a country page
This is the institutional landscape of Australia's intelligence apparatus as it is documented in the public record. Each card above links through to a full agency profile — the service's founding date, statutory basis, jurisdiction, parent ministry, headquarters, official channels, and a structured account of role, history, and notable operations footnoted to primary sources. The agencies on this page may overlap institutionally (a foreign-intelligence service and a signals-intelligence service often share missions and personnel) and may operate against one another in counter-intelligence terms; the country page does not impose a hierarchy among them, only an inventory.
If a particular operation or scandal is what you are looking for rather than the institutional background, see the Dossiers — long-form pieces that cross agencies and countries. The methodology page documents how operations are categorised as confirmed, alleged, or disputed, and what the public record can and cannot tell us. The Lexicon defines the terms that recur across these pages — HUMINT, SIGINT, covert action, plausible deniability, station, asset, finding.
Coverage here grows as new declassifications expand what can responsibly be said about services that remain partly closed. Some agencies have full reference entries; others are stub entries pending the full treatment. Stubs are kept on the index so navigation between related services is preserved while the detailed text is written.
