Amnesty International in Australia says Nauru could be left with the asylum seekers the developed world is not willing to take on.
As a ministerial meeting in Bali in Indonesia on People Smuggling got underway, the organisation said practices such as the so-called Pacific Solution were creating two classes of asylum states.
There were the rich and the powerful states that could select whom they would accept as refugees, and the rest.
Dr Graham Tom, the Refugee Co-ordinator for Amnesty International Australia, says there are still more than four hundred people on Nauru whose future is unclear:
"You still have a small number of people who have been recognised refugees, who are still on Nauru because, you know, the international community hasn't taken those people for resettlement. So you can see a situation, certainly, where you know the ones that the first world doesn't want to select, will be stuck in transit camps around the region."
