Manus Island detainees

Fairfax reported the Australian Border Force told the committee the estimated cost of services would be between $AU150 and $AU250 million for 12 months from 1 November.

Australian Border Force deputy commissioner Mandy Newton said Australia was required to maintain services after they were discontinued at the centre.

"What I'm telling the committee is that all services will stop on the 31st of October and all residents of the facility will be expected to live in the alternate facilities where they'll receive all services."

More than 1,900 Manus Island detainees had alleged they suffered serious physical and psychological injuries during their time on the Papua New Guinea island.

Australian law firm Slater and Gordon, who represented the plaintiffs, confirmed Wednesday a deal had been struck with the government, although it had yet to be approved by the court.

35-year-old Iranian Majid Kamasaee, who was detained on the center for 11 months after fleeing Iran, was the lead plaintiff in the case.
