As protests at the other Australian-run detention centre on Nauru enter day 56, those in the Manus Island centre have holding signs and chanting "Freedom, Freedom" and "This place is illegal".
The centre in PNG was ruled unconstitutional by the country's Supreme Court, prompting the Prime Minister, Peter O'Neill, to vow to close it.
However the Australian authorities said this might take some time and repeated that the refugees and asylum seekers would never go to Australia.
