I do not see a Victorian death registration for him in 1928.
However NSW BMDs show this death registration
13635/1928
James BUSHELL, father John, death registered LISMORE district.
In the column for mother's name it says "85 yrs, LISMORE"
I have occasionally come across death registrations which have been made in a particular registration district while the place of death is quite different.
You may find his death certificate gives his date of arrival - if the informant knew it. Victorian certificates often have that information, but I have little experience of NSW certificates.
You probably know that Transcription agents in NSW are a cheaper and quicker source for certificate information. Their names and contacts are on the NSW site:
