The government will pay $70 million in the settlement of a class action brought by Manus Island detainees.

Detainees who say they have endured hell on Manus Island will share $70 million in compensation but the government maintains none will find homes in Australia.

The 1905 current and former Manus Island detainees say their voices are finally being heard after they secured what is believed to be the largest human rights class action settlement in Australia.

The government and operators of the Manus Island Regional Processing Centre settled the class action for $70 million plus costs estimated at more than $20 million, without any admission of liability.

Slater and Gordon principal lawyer Andrew Baker said the settlement was an important step towards recognising the extremely hostile conditions the detainees endured on Manus Island.
