Amnesty International has released a new report detailing fears dwindling health care services provided to detainees on Manus Island are putting lives at risk.

Researchers from the human rights organisation visited Port Moresby in November 2017 to speak with refugees and asylum seekers sent from Manus for medical treatment.

Amnesty outlined in their report that detainees were having to wait for months for treatment of suspected cancerous lumps, kidney stones, typhoid and dengue fever.
