Is he mentioned on his parents death certificates - 1954 & 1959?
http://trove.nla.gov.au/ndp/del/page/1073223?zoomLevel=1 - here is his mother's death notice. Lists three children (he is presumably "Vic") and a granddaughter.Since the two girls (who can be seen on bmd) both married, it's probable the granddaughter mentioned is one of theirs.
Here is death notice for Lyle Le Sueur from SMH 22 Jan 1993cheers, Ros
