The asylum seekers involved in the class action are now spread across the world.
On the latest count, 856 remained at the Manus Island detention centre while 103 lived elsewhere in PNG.
Six asylum seekers involved in the proceeding are in Nauru, 54 are in immigration detention in Australia, 11 are in community detention and one is in criminal detention.
Almost 400 are living in the Australian community on a bridging visa or waiting for their status to be determined.
More than 500 group members had been in the care or in contact with the International Organisation for Migration to return to their country of origin.
And 425 detainees have done just that, with most returning to Iran and smaller numbers going back to Vietnam, Iraq, Lebanon, India and several other countries.
