VH-ATD was delivered to the Australian Department of Transport, Air Transport Group, in 1977. Aviation bureaucracy in Australia was in state of endless reorganisation as governments changed. The Air Transport Group became the Department of Aviation then the Civil Aviation Authority, which was the operator in 1992. Before VH-ATD left Australia for Canada in 1998, the CAA had split in two, with the airways inspection F28 moving Airservices Australia.
