A major milestone has been reached for the expansion of Acacia Prison, with Sitzler Pty Ltd awarded a $238.5 million design and construct contract for the project.

The contract includes the delivery of three new accommodation units, increasing capacity by 480 beds.

The project also includes a new support services building for education and allied health services and an industry building for prisoner industries, programs and services.

Acacia is a privately-operated medium-security facility for adult male prisoners in Wooroloo, approximately 50 kilometres east of Perth.

The facility operates with a strong focus on rehabilitation, supported by a range of prisoner industries and employment programs.  

The project will provide purposeful accommodation, activities and amenities with a focus on creating job pathways and connections to community.

The expansion is part of the Department of Justice's Long-Term Custodial Infrastructure Plan 2025-2035, with the project expected to be delivered by 2029.
