People with disabilities in prisons across Australia are at serious risk of sexual and physical violence, and are disproportionately held in solitary confinement for 22 hours a day. Prisoners with psychosocial disabilities – mental health conditions – or cognitive disabilities in particular can spend days, weeks, months, and sometimes even years locked up alone in detention or safety units. State and federal governments should end the use of solitary confinement for prisoners with disabilities, ensure that appropriate services are available to meet their needs, and more effectively screen prisoners for disabilities as they enter prison.
