Story highlights 1,905 detainees brought the class action against the Australian government

Australia Immigration Minister said the settlement was not an admission of liability

(CNN) The Australian government has agreed to pay detainees on Manus Island more than $70 million (US$52.75 million) in the "largest settlement in a human rights class-action" in the country's history.

More than 1,900 detainees had alleged they suffered serious physical and psychological injuries during their time in the Australian government's offshore asylum seeker detention center on the Papua New Guinea island, between 2012 and 2016.

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.

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

"I came to Australia seeking peace but I was sent to Manus which was hell," Kamasaee said in a statement after the announcement.
