Just to confirm an earlier posting.... The BN2 construction list does indeed show VH-AIA as being the first registered in Australia.
It was construction number 15 and was delivered on the 15 March 1968 to Island Airways. Later transferred to Tangalooma Air Taxis in 1978.
In 1979 it was re-registered H4-AAH with Solair. Then P2-ISR with Transniugini Airways in 1991.
It was written off on 24 December 1993 at Mount Hagen-Kagamuga Airport PNG.
