I Am Looking for a James Rutherford Who was Born IN New Zealand but Lived IN Sydney Bondi IN the Late 1950 S and Worked on Cruise Ships Around...

He would be around 80 years of age maybe a little younger if still alive..There was a James Rutherford who was on a ship that went from Strathmore to Fremantle Australia in June 1960 which could be him.This man I have just discovered is my father.Not sure where to go to search? Thanks.....
