The main emphasis of the collection is on the development of the public service in the Territory of Papua and New Guinea and the establishment of educational and training bodies including the Public Service Institute and the Australian School of Pacific Administration. There are also files on more general topics including the early history of British New Guinea (Papua) and German New Guinea, local government, native affairs, political and economic development, missions, employment of non-Europeans, the origins of mandate, army occupation and war years, post-war reconstruction and public health.
