Of interest, the Far North Queensland operator now flys seven aircraft on passenger and freight charters throughout the Torres Strait and the Northern Peninsula Region. including Cessna 208 Grand Caravan VH-TLZ, along with an Aero Commander 500, four Islanders, and one Cessna (single piston) U206G.
