Australia has six states; New South Wales (NSW), Queensland (QLD), South Australia (SA), Tasmania (TAS), Victoria (VIC) and Western Australia (WA) and two major mainland territories; the Australian Capital Territory (ACT) and the Northern Territory (NT). These states and territories assume major responsibilities and powers for social issues, including legislative powers for the administration of criminal justice. Australia, therefore, has no single criminal justice system. States and territories have separate and independent systems of police, courts, prisons and juvenile institutions, and other corrective and treatment services.
