Asia Pacific Airlines is based in Tabubil, Papua New Guinea. It is a subsidiary of Cobham Aviation and the Dash-8's arrival into Adelaide is presumably to undergo maintenance.
Asia Pacific Airlines operates a fleet of three Dash-8-100 aircraft on domestic services, as well as flights to Cairns on behalf of Ok Tedi Mining Limited of which P2-NAZ wears the colours and titles.
Meanwhile, also on Saturday 20 March, the Queensland Government Airwing (State of Queensland) Raytheon B300 Super King Air VH-SGQ was noted departing Longreach Airport for Brisbane. As mentioned below, it had arrived the previous day.
