You Don't Get to Decide

Involuntary detention under mental health legislation is one of the most significant deprivations of liberty available under Australian law outside of the criminal justice system. It can be ordered without a court hearing, based on clinical assessments, and extended with relatively limited external oversight. For the person detained, the experience is often one of profound powerlessness — physically confined, subjected to treatment they may not have chosen, and frequently told — explicitly or implicitly — that their objections are themselves symptoms of their illness. This area is governed by state and territory legislation — the principles described here are consistent across Australian jurisdictions, though specific provisions vary. Every Australian state and territory has its own Mental Health Act, and the details of detention criteria, review processes, and patient rights differ between jurisdictions. However, all schemes must operate consistently with common law rights and Australia's international obligations, particularly under the UN Convention on the Rights of Persons with Disabilities (CRPD), which Australia has ratified. The CRPD takes a strong position on the rights of people with mental health conditions: it requires that all persons have access to legal support, that detention decisions be subject to independent review, and that people not be denied legal capacity solely on the basis of a mental health diagnosis. In practice, these protections are often not communicated to detained patients, who may not know they can request a lawyer, contact a mental health advocate, or apply for a review of their detention order. Knowing these rights — and knowing them before a crisis — can be life-changing.
