The Territory of Papua and New Guinea , officially the Administrative Union of the Territory of Papua and the Territory of New Guinea, was established by an administrative union between the Australian-administered territories of Papua and New Guinea (the latter being a United Nations trust territory administered by Australia) in 1949. In December 1971, the name of the Territory changed to "Papua New Guinea" and in 1975 it became the Independent State of Papua New Guinea.
