Also, it appears that West Wing Aviation have added another 19-seat Beechcraft 1900. It is believed that VH-EMK - a Beechcraft 1900C - has joined the fleet.
-EMK arrived from Perth (YPPH) via Alice Springs (YBAS), Mount Isa (YBMA) and Townsville (YBTL) on Tuesday 13th January.
In a media release published on Wednesday 14th January (which can be found HERE), West Wing Aviation stated that "An additional 19 seat aircraft arrived yesterday".

-EMK increases West Wing Aviation's fleet of Beechcraft 1900s to two.
The media release also states: "it is expected two 36 seat aircraft will be introduced during February 2015".
It is currently not known as to what type the 36-seat aircraft is, nor where they will come from, but there is speculation that it might be two ex. Skytrans Dash 8-100s, which can seat 36.
