The Refugee Action Coalition said 147 refugees from Manus had been accepted by the US so far, but over 600 remain in limbo on Manus or in Port Moresby and around 800 remain on Nauru.
The US is reluctant to accept Iranians, Somali, Sudanese, Iraqi or Syrian refugees for resettlement.
The coalition's Ian Rintoul said the failure of the US deal had left the PNG and the Australian governments with a major humanitarian and refugee rights issue.
