Australian Federal Police say they may look into claims staff at the Manus Island asylum seeker detention camp in Papua New Guinea are avoiding standard police checks.
The AFP has confirmed it has received a complaint that some camp staff have evaded questioning on issues such as their suitability for working with children and that they submitted fraudulent records.
Enquiries have started into the way International Health and Medical Services, which provides care services at the detention camp, employs its staff.
Australian Greens senator Sarah Hanson-Young says she laid a police complaint this week over concerns at the standard of care for refugees and the possible deception of the immigration service.
The Federal Police say the complaint is currently being evaluated to determine if further investigations will go ahead.
