G4S Custodial Services Pty Ltd

Mount Gambier Prison

The Mount Gambier Prison is the newest institution and it is the first and only prison to be privately managed in South Australia.

The South Australian Government owns the land on which the prison is located and also owns all plant and equipment and facility infrastructure at the prison.

The department partners with G4S Custodial Services Pty Ltd (under a single supplier contract) for the management and operation of the prison, which caters for Medium and Low Security sentenced and remand prisoners.

G4S Custodial Services Pty Ltd (G4S) provides all services for the management and operation of the prison, including but not limited to:

  • prisoner security and management (including assessment, case and sentence management)
  • prisoner programs, education and prison industrial programs
  • centre security (including perimeter security)
  • prisoner services (including food services)
  • staff training and accreditation
  • maintenance of the physical infrastructure.

Depending on security classification and regimes to be applied, the prisoners may be accommodated in Low Security cottage style units or higher security cellblock units.

Prisoner Movement and In-Court Management Services

G4S is also responsible for the contract for the transportation of prisoners and management of prisoners in court. This contract is administered by DCS on behalf of participating agencies.

The contract provides for the movement of most prisoners between prisons, courts, police stations and health services. The contract/G4S is not responsible for the transfer of prisoners with a High1 Security classification.
