The Refugee Action Coalition is concerned there is no system for making complaints at the asylum seeker processing centre in Papua New Guinea.
A spokesman for the Australian contractor Transfield Services, David Jamieson, says he does not know the exact process for asylum seekers to make complaints at the Manus Island facility.
But given the given the size of the facility, Mr Jamieson says asylum seekers would have no difficulty in making concerns known.
Transfield, which provides welfare and security services at the centre, earlier confirmed a staff member had been dismissed for serious misconduct after a complaint from other staff, not a detainee.
A coalition spokesperson, Ian Rintoul, says he would not be surprised if there was no process.
"The complaints and the concerns of the asylum seekers, which should be their primary consideration are really the last on the agenda. Transfield has accepted a contract and a brief from the Immigration Department and the fact is that it is for profit in any case, the fact that it is so politically motivated means that the welfare and the concerns of the asylum seekers are the very last of the considerations."
