The Province of South Australia's Police Force was founded in April 1838. This searchable database of more than 2,800 police who had left the force by 1920 includes Northern Territory police until taken over by the Commonwealth Government in 1911, and gold escort troopers.
There are numerous discrepancies in the spelling of names and between dates & ages in the various records. Some have been resolved.
