NSW Department of Justice’s objective

To provide additional inmate capacity within the Sydney metropolitan area.


The NSW Department of Justice had experienced a significant rise in the number of inmates. 

The Parklea Correctional Centre Expansion provides an additional 650 beds, almost doubling the capacity of the existing centre. The extension was being built to contemporary standards and fully integrate into the existing centre, making it safe and secure for staff and inmates.

Johnstaff’s role

Johnstaff was engaged by the NSW Department of Justice as Project Manager for the delivery of its $200m expansion of the Parklea Correctional Centre. 

This role involved managing the design, delivery and commissioning of two separate projects: a 150 bed expansion of the existing Parklea Minimum Security Centre; and a 500 bed expansion of the existing Parklea Maximum Security Centre.

Addressing the issues

This project is part of a NSW expansion program, which aims to deliver a prison system that accommodates more inmates, operates more efficiently and has a greater focus on rehabilitation.

The design of the expansion was developed to meet contemporary standards, while also integrating into the existing prison systems and improving operational procedures.

The expansion needed to be constructed within and around the existing operational centre, maintaining security and safety at all times. We undertook detailed planning of all works staging and methodologies to prepare for works. We also conducted extensive stakeholder liaison before, during and after all works to ensure that there were no disruptions to operations. 

The Parklea Correctional Centre is now well-placed to meet the demand for greater corrective services capacity in metropolitan Sydney.
