ADF: past operations in Timor-Leste (East Timor)
After supporting the UN-sponsored referendum on self-determination in August 1999, units of the Australian Defence Force (ADF) were deployed to Indonesian-occupied Timor in September 1999, as the leading force in the International Force East Timor (INTERFET). INTERFET was a United Nations-mandated multinational force formed to address the deteriorating humanitarian and security situation.
INTERFET troops operated in Timor from September 1999 under the commander of ADF Major-General Peter Cosgrove, before the handover to the United Nations Temporary Administration in East Timor (UNTAET) in March 2000.
Australian INTERFET troops were gradually withdrawn from Timor after 2000, but new ADF forces were deployed in May 2006, following major rioting in the capital Dili.
In mid-2009, ADF units are still deployed in Timor under Operation Astute and Operation Tower. Australian Federal Police (AFP) officers are also operating in Timor through Operation Serene.

Operation Faber, 19 June – 15 September 1999
