It seems Britten Norman BN2A MK III-1 VH-BSP and sister ship VH-BSG were operated by Burnett Airways in the late 1970's or 1980's.
There was another Trislander in West Australia used as a geological survey aircraft with wire antenna strung all around it. It may have been VH-NKW?
I just found this:
Press Release - 13 February 2003
Britten-Norman Aircraft group is to re-start manufacture of the Trislander regional commuter aircraft.
Powered by three 260 hp Lycoming engines, the Trislander has proved a popular complement to the Islander and is the only single-pilot civil aircraft capable of carrying 17 passengers. The first new Trislander is being built at BNA's UK factory at Bembridge on the Isle of Wight. It will be used as a demonstrator, undertaking a world tour to convert current high levels of interest into the firm orders required for BNA to move back into full scale production.
Hopefully it never happened!
