Immigration Minister Peter Dutton says he does not expect Australia will have to renegotiate its contract now that the Manus Island detention centre is an open facility.
Papua New Guinea authorities are allowing asylum seekers and refugees on Manus Island to leave the centre during the day, in order to comply with a PNG Supreme Court ruling that the centre breached the men's constitutional rights.
"I don't think it does (require renegotiation) - there are still support services that are provided, we provide funding to the PNG government and organisations," Mr Dutton told reporters in Canberra on Thursday.
Mr Dutton said it was up to the PNG government to comment on how the facility operates.

"The Australian side has made it very clear that people won't be settled in Australia and the PNG side has made it very clear that they want to comply with the ruling of the court," he said.
"They're a sovereign nation and they have responsibility for their processing centre."
