Aboriginal deaths in custody is a political and social issue in Australia. It rose in prominence in the early 1980s, with Aboriginal activists campaigning following the death of 16-year-old John Peter Pat in 1983. Subsequent deaths in custody, considered suspicious by families of the deceased, culminated in the 1987 Royal Commission into Aboriginal Deaths in Custody (RCIADIC).

Punishment in Australia arises when an individual has been accused or convicted of breaking the law through the Australian criminal justice system. Australia uses prisons, as well as community corrections. When awaiting trial, prisoners may be kept in specialised remand centres or within other prisons.
