Alexander (or Alec) Riley served with the NSW Police until his retirement in 1950 with the rank of sergeant.
I have read reports that Riley was once denied access to a property to search for a lost child because of the racism of the property's owner, the grandfather of the child. He later returned after the property owner had died and found the child's remains. I can't find the original report I read, but I have found mention of the incident in 'Tracker' Riley's great-great nephew revisits history with stage performance.
This also led me to information on two other renowned trackers, both called Jimmy James:
Jimmy James (tracker, died 1945)
Jimmy James (tracker, died 1991)
