The International Organisation for Migration says it's open to again being engaged by Australia to provide services to asylum seekers held on Nauru.
This comes as Australia's Senate passed legislation to pursue offshore processing on Nauru and Papua New Guinea's Manus Island.
The IOM provided food, shelter, clothing and other services at the Nauru and Manus Island detention centres when they were first opened by the former Australian government 11 years ago.
The IOM chief of mission in Australia, Mark Getchell, says they have again been approached by Canberra.
"All we've had is a call to ask, would IOM be amenable to becoming involved. IOM's response has been we would open to that, in principle, as long as IOM's role would be to make the lives of migrants in this situation better and more dignified if we can provide services to that end."
