They support the work of the State's court system, providing security at court complexes; enforcing writs, warrants and property seizure orders; and managing the jury system. The Office was established in 1824; prior to this its functions were exercised by the fledgling colony's provost marshal. The NSW Sheriff's Office managed NSW prisons until 1874.
