Building better and safer corrections and rehabilitative facilities.

Dillwynia Correctional Centre Expansion

Dillwynia Correctional Centre, a maximum-security facility for female offenders is part of the Francis Greenway Correctional Complex located 5km south of Windsor. The expansion comprised an additional 248 beds and state of the art educational facilities to cater to Sydney’s growing metropolitan population.

The $153 million project was part of NSW Government’s $3.8 billion Better and Safer Prisons program which addresses overcrowding and provides expanded access to rehabilitative and other educational programs to help reduce recidivism. More beds in the Sydney metropolitan area allows inmates to be closer to Sydney courts, cutting travel times.

The project included increasing the total size of the site from seven-hectares to 10 hectares. The new facilities include a visitor processing building; a health, reception and industries building; a programs and inmate services building; an education building; a segregation building; five accommodation buildings, a carpark and recreation areas.

The new maximum-security blocks will better support Dillwynia’s “graduated living” model that allows inmates to remain at the same facility for the duration of their sentence. This improves stability for the inmates and makes it easier to deliver training and programs aimed at reducing reoffending.
Key to the project was the substantially enhanced mental health service to support individual recovery, and reflected throughout the design which incorporated extension program and inmate services and recreation areas and trauma-informed landscaping.
