Crime in South Australia

Crime in South Australia is prevented by the South Australia Police (SAPOL), various state and federal courts in the criminal justice system and the state Department for Correctional Services, which administers the prisons and remand centre.

Crime statistics from the 2017–18 national ABS Crime Victimisation Survey show that between the years 2008–09 and 2017–18, the rate of victimisation in South Australia declined for assault and most household crime types.
