Military history of Australia during the Indonesia-Malaysia Confrontation

The Indonesia-Malaysia confrontation (Indonesian: Konfrontasi) was fought from 1962 to 1966 between the British Commonwealth and Indonesia. Indonesia, under President Sukarno, sought to prevent the creation of the new Federation of Malaysia that emerged in 1963, whilst the British Commonwealth sought to safeguard the security of the new state. The war remained a limited one however, and was fought primarily on the island of Borneo, although a number of Indonesian seaborne and airborne incursions into the Malay Peninsula did occur. As part of Australia's continuing military commitment to the security of Malaysia, Australian army, naval and air force units were based there with the Far East Strategic Reserve, mainly in the 28th Commonwealth Infantry Brigade Group.

The Australian Government was initially reluctant to become involved in the conflict, and Australian forces did not see combat until 1964. Australia's involvement expanded in 1965, however, following repeated requests from the British Government with an Australian infantry battalion and special forces being deployed to Borneo where they were involved in a number of actions against Indonesian Army units. Other army units deployed included artillery batteries and engineers, both of which served tours in support of the infantry in Borneo. A number of RAN warships also patrolled the waters off Borneo and Malaysia to deter Indonesian infiltration parties, and were involved in shelling Indonesian positions in Borneo and in repelling infiltrators in the Singapore Strait. The RAAF played only a relatively minor role, although it would have been used far more extensively had the war escalated.
