Five Australian government agencies are involved in programmes of co-operation and assistance with States in the Asia Pacific region, in particular with Indonesia and Papua New Guinea. These agencies are the Department of Infrastructure and Transport, the Civil Aviation Safety Authority, the Australian Transport Safety Bureau, Airservices Australia and the Australian Maritime Safety Authority. The co-operation and assistance programmes enhance regional aviation safety through training, mentoring, and capability building activities. Australia actively supports the Pacific Aviation Safety Office (PASO), a cooperative regional safety oversight organization created to assist its Member States in meeting international obligations. As a member of PASO, Australia is providing support and practical assistance to the Organization.
