Yes, that was the IPEC Argosy - another name was the "pregnant Viscount".which operated out of EN to TAS for most of the '70's.
When the Belfast came out of RAF service about half the fleet (6 or 7) went into civil service with Heavylift. They came to Oz quite often in the '80's, many times thru Darwin and usually with cargo that was bulk rather than weight. One thing they were good at.
They have slowly being "retired" from service and the one that seems to live at CNS is the last flying example, although I do understand one of the others is being worked on in the UK.
A grand bit of "british engineering"
