I think you are confused with two Ansett Group Vicount crashes:
- 22 September 1966: VH-RMI Nadjayamba Station, Winton Queensland. Ansett. (Left wing spa failure following a fire.)
- 31 December 1968: VH-RMQ Indee Station, Port Hedland, WA. McRobertson Miller (leased from Ansett. Right wing spa failure.)
(VH-RMQ originally went into service with TAA [Trans-Australia Airlines] in 1954 as VH-TVB "Gregory Blaxland". MMA named VH-RMQ "Quininup" after they leased it from Ansett in September 1968.)
The third Australian Viscount crash occurred 30 November 1961, VH-TVC Sydney, Ansett Airlines.
Jack, I vaguely recall travelling in a Viscount Brisbane - Port Moresby (via Townsville?) around 1963 (when the scheduled Electra went U/S) and seem to recall it was in mixed class seating. Don't recall if it was Ansett or TAA.
The Viscounts also operated Melbourne - Hobart well after the Electras went into service.
