The governments of Papua New Guinea and Australia say they are working together to close the Manus Island processing centre.
PNG's Supreme Court ruled a year ago that holding the men on Manus against their will was illegal, leaving it incumbent on both governments to close the centre.
It remains unclear where the governments will send the majority of the over 800 men held on Manus who have been found to be refugees.
Canberra has excluded them from ever settling in Australia
However Australia's government has sealed a deal to send some of the refugees to the US, with American officials currently reviewing which refugees it might take.
While Canberra insists it is PNG's responsibility to resettle the balance, PNG's government says most of the refugees don't want to stay.
PNG's Foreign Minister Rimbink Pato told Johnny Blades both governments agree the Manus processing centre will be closed by October 31st.
