The prison holds high, medium and low security prisoners, and is South Australia's main induction and reception prison for male prisoners. It still retains industry facilities that are the largest in the South Australian prison system, and is run by the South Australian government's Department for Correctional Services. Some of the original buildings and parts of old equipment can still be seen from a creek level walking trail, between the prison and new suburb of Walkley Heights. These include guard towers, quarries, a blacksmith's shop and a gunpowder magazine
