Greenough Regional Prison (Greenough) holds prisoners of all security classifications, minimum, medium and maximum (remand only). It accommodates sentenced and remanded men and women. Greenough opened in 1984 as a minimum-security facility. It was upgraded in 1990 to a medium-security prison.
A riot occurred in July 2018 which badly damaged infrastructure and impacted staff and prisoners’ sense of safety. Following this, a standalone women’s precinct (Unit 4) was opened in 2022. Recent population pressures resulted in women being transferred out of Greenough to accommodate additional men. In June 2024, women returned to Greenough but were placed in Unit 5, which is small, crowded and lacks fit for purpose infrastructure.
