Hodan Yasin was transferred to Australia for treatment after setting herself on fire and sustaining severe burns to most of her body.
One person told the Australian Guardian the incident was worse than when 23-year-old Omid Masoumali died last last week after self-immolating, also on Nauru.
Last November, Yasin was treated in Australia for a head injury obtained in a motorbike accident but was forcibly returned to Nauru last Wednesday, the Refugee Action Coalition said.
Many refugees arriving in Australia by boat are refused entrance and relocated to offshore islands.
Labor Party immigration spokesman Richard Marles is demanding to have the situation on the islands rectified. He said Prime Minister Malcolm Turnbull “must urgently seek a viable agreement to resolve the fate of people on Manus Island and Nauru.”
Yasin had been held in Nauru for three years until being transferred to Brisbane, Australia. Last Wednesday, she screamed as she was forcibly carried out of the site.
The United Nations has been critical of Australia’s offshore detention program.
A report by the Australian Human Rights Commission exposed the life of migrant children living in government detention centers, where some have reportedly attempted suicide.
