The Australian Security Intelligence Organisation (ASIO), Australia's domestic counterintelligence service, is responsible (in coordination with the Australian Federal Police) for preventing espionage by foreign powers, and is attempting to monitor and prevent terrorist and other political violence . It is approximately equivalent to Britain's counterintelligence service, MI5.

It is often referred to as the Australian Secret Intelligence Organisation, especially in left-wing political literature critical of the organisation, but this name has no official standing.

ASIO came to prominence in the 1950s with the Petrov affair. Throughout the 1960s, like other Western intelligence agencies it monitored the activities of Vietnam War protestors and others on the political left (some of whom were involved in espionage for the Soviet Union but many more who were not). The distrust engendered in the Australian Labor Party led to a raid on the ASIO offices by the new Attorney-General, Lionel Murphy in 1972 when Labor won office.

Conspiracy theorists accuse ASIO of being guilty of the Hilton Bombing, which is the only modern act of terrorism on Australian soil.

Oversight

ASIO has more political and judical oversight than its partner agency NZSIS, but the extent and kinds of oversight are not the same as Canada's (CSIS) .
