Forty asylum seekers considered as "high-risk" have been moved from the Manus Island detention centre in Papua New Guinea to the asylum seekers camp in Nauru.
The forty were flown to Nauru accompanied by thirty Australian police, three interpreters and an immigration official.
Just over 150 boatpeople remain on Manus..
Meanwhile reports say Australia is hoping to extend the agreement with Papua New Guinea to process asylum seekers beyond the official October 20th deadline.
Under the Australian government's Pacific Solution, Australia pays Nauru and PNG to house asylum seekers while their applications are processed.
