You have not mentioned any record of the man's death.
Where was it registered? Wouldn't the ship's name be shown?
What about his estate. Will, Probate application?
There is not a record of probate being applied for in Australia, so his affairs were dealt with in UK after death.
Other than that, my suggestion in Reply #14. his grandchildren might have knowledge.

Hi Sue
My guess is that, as he died at sea, the death is registered in the country where the ship is registered, but I could be wrong on that. The problem is that I don't know the ship's name. I am going to look for ship arrivals in Southampton around the same date and see if that get me anywhere. Given it was in the 1970's I suspect that there weren't too many voyages in those days as plane travel was so much faster.
The GRO has no death certificate for him. I see no probate either so he could have died intestate.
I am really only in contact with the English side of the tree, and even those have no idea what happened. The one surviving child of his that I suspect could help has advanced dementia so that avenue is closed off too, sadly.
Thank you for helping.
Kindest regards
