I did an Australia-wide search on Findagrave with the date 1950 +/- 10yrs and found only one grave record. Could this be him? https://www.findagrave.com/memorial/200227854/joseph-levine
The birth date (1881) is not quite the same but I was always told to never trust the data supplied on death.
Expanding the search to +/- 25 years did not yield anymore names.
