Three people who killed themselves in a Sydney immigration detention centre all received appropriate mental health care, an inquest has found.
But it was unclear why detainees at Villawood detention centre routinely did not take their medication or attend medical appointments, the inquest said.
Villawood, in western Sydney, was operated by the private operator Serco at the time of each of the suicides, and health services in the centre were managed by International Health and Medical Service.
The health services are now run by another provider, and Secure Journeys, a local subsidiary of Management & Training Corporation (MTC), will soon take over operation of Villawood from Serco.
The inquest recommended the federal government commission an independent study to examine why detainees routinely do not take their medication, or attend appointments.
