The company that will manage health services, including mental health services, for detainees on Nauru is at the centre of criticisms that the mental health problems of asylum seekers detained on Christmas Island and on mainland camps have been poorly handled.

International Health and Medical Services, which is owned by the international services group International SOS, currently holds the $780 million contract for the provision of health services in the Department of Immigration's detention centres. The company will receive an additional $22 million to provide health services on Nauru.
