Evidently we can't believe
everything the RFDS says.
From the website,
The RFDS has 4 different planes that are used for operations. These are the Hawker 800XP (used in WA and NT), the Pilatus PC-12 (used in SA/NT and WA), the King Air B350 C and B200 C (used in Qld, NSW, Victoria and Tasmania) and the Cessna C208 (used in Qld).
