Crime in South Australia is managed 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 for all categories of offence in the state are provided on the SAPOL website, in the form of rolling 12-month totals. 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.
- Beaumont children disappearance on Australia Day in 1966 - still unsolved.
- Snowtown murders (1992-1999) - serial killings which occurred mainly in two outer-suburban suburbs of Adelaide, Salisbury and Elizabeth
- The Family Murders (1970s-mid-1980s)
In addition to the various federal courts, justice is administered by the Supreme Court of South Australia, the District Court, the Magistrates Court and the South Australian Civil and Administrative Tribunal.
