The federal Government has rejected claims by 23 former staff of the Nauru asylum-seeker detention centre that it was told about multiple allegations of child sexual abuse more than a year before it commissioned an inquiry.
In an open letter published on Tuesday, the 23 former teachers, social workers and child protection staff said the Government and Department of Immigration had "tolerated the physical and sexual assault of children, and the sexual harassment and assault of vulnerable women in the centre for more than 17 months".
The Government says it learned of the allegations only late last year, when it ordered a review by Philip Moss, a former Integrity Commissioner. At that time, it also expelled 10 Save the Children Australia staff from Nauru, accusing them of encouraging protests and self-harm and "coaching" asylum-seekers to concoct abuse allegations.
Moss, whose report was released last month, found nothing to substantiate those claims. He did uncover several dozen cases of alleged abuse, including rape, sexual and physical assault of children, guards trading marijuana for sex, and a guard demanding to see a female detainee naked in exchange for two minutes longer in the shower.
That prompted the Immigration Minister, Peter Dutton, to declare that he had "zero tolerance" for any form of sexual abuse. But the signatories to the open letter said that commitment was not reflected in "the attitude or actual response" of his officials.
