The Manus Regional Processing Centre, or Manus Island Regional Processing Centre (MIRCP), was one of a number of offshore Australian immigration detention facilities. The centre was located on the PNG Navy Base Lombrum (previously a Royal Australian Navy base called HMAS Tarangau) on Los Negros Island in Manus Province, Papua New Guinea. In October 2021, the Australian Government cut off all support to the 124 remaining men on the island, leaving PNG to take over responsibility for them.
