Australian military involvement in peacekeeping operations has been diverse, and included participation in both United Nations sponsored missions, as well as those as part of ad hoc coalitions. Indeed, Australians have been involved in more conflicts as peacekeepers than as belligerents; however, according to Peter Londey "in comparative international terms, Australia has only been a moderately energetic peacekeeper."[1] Although Australia has had peacekeepers in the field continuously for 60 years โ the first occasion being in Indonesia in 1947, when Australians were among the first group of UN military observers โ its commitments have generally been limited, consisting of small numbers of high-level and technical support troops (e.g. signals, engineers or medical units) or observers and police. David Horner has noted that the pattern changed with the deployment of 600 engineers to Namibia in 1989โ90 as the Australian contribution to UNTAG.[2] From the mid-1990s, Australia has been involved in a series of high-profile operations, deploying significantly large units of combat troops in support of a number of missions including those in Cambodia, Rwanda, Somalia and later in East Timor. Australia has been involved in close to 100 separate missions, involving more than 30,000 personnel and 11 Australians have died during these operations.[3][4]
