Recently, a BAe146 has been operating into Karratha. I remember a few years ago a 146 was operated by Qantaslink but these were all replaced later by 737s.
Callsign I think is NJ* (didn't catch the last character) but am guessing it is on hire from National Jet.
Does anyone know what is going on with the 146? It's good to see a variety of aircraft up here.
