Australian of the Year Rosie Batty has called for the closure of Manus Island and Nauru immigration detention centres.
The prominent campaigner against domestic violence, in an open letter sent to Prime Minister Malcolm Turnbull by a group of academics known as Researchers Against Pacific Black Sites, said the Australian-run centres were too dangerous for vulnerable people to be detained there.
"These centres cannot be patched up, they must be shut down," Ms Batty said after claims this week that two female refugees had been raped on Nauru.
