An SASR troop was deployed to Timor Leste in May 2006 as part of Operation Astute, operating alongside a Commando Company Group as part of the Special Forces Component following renewed unrest there. On 4 March 2007, along with the commandos, SASR personnel took part in the Battle of Same during which five rebels were killed during an unsuccessful attempt to apprehend the rebel leader, Alfredo Reinado. It was reported in October 2006 that 20 SASR operators were in the southern Philippines, supporting Filipino operations against the Abu Sayyaf and Jemaah Islamiah terrorist groups, but this was denied by the Department of Defence. Meanwhile, following tensions in Fiji between the military and the government the Australian Government dispatched three naval vessels in November and December 2006 as part of Operation Quickstep, in preparation for a potential evacuation of Australian citizens. On 29 November 2006, a Black Hawk helicopter from the 171st Aviation Squadron carrying four crew and six soldiers from the SASR crashed while attempting to land on HMAS "Kanimbla" and sank in international waters off Fiji. The helicopter's pilot and a soldier from SASR were killed in the crash.
