Papua New Guinea (PNG) achieved independence from Australia on September 16, 1975, becoming a member of the Commonwealth of Nations and a constitutional monarchy with Elizabeth II as its Queen. The Papua New Guinea Independence Act 1975 was an Act passed by the Parliament of Australia. It replaced the Papua and New Guinea Act 1949, and changed the status of the Territory of Papua and New Guinea to that of an independent Papua New Guinea. The Act set 16 September 1975 as the date of Papua New Guinea's independence and terminated all remaining sovereign and legislative powers of Australia over the country.
