The Department of External Affairs was an Australian government department that existed between December 1921 and November 1970.
When it was first established, the department was linked administratively to the Prime Minister's Department, with the secretary to the Prime Minister's Department also acting as the secretary to the Department of External Affairs. The minister of the department until 1932 was the prime minister of the day. The department was first given its own permanent head in 1935, with William Hodgson appointed Secretary (all previous heads had served simultaneously as secretary of the Prime Minister's Department).
Between 1940 and 1946 the department grew from an organisation with less than 20 people and two overseas posts to one with nearly 300 people, and representatives in 14 countries.[1]
In 1961, the department introduced a special $20,000-a-year language-training program for its junior diplomats. The program was still operating in 1967, with the aim to assist diplomats achieve proficiency in the local languages of the countries in which they were serving.[2]
In 1970, under the Gorton government, the department was abolished and replaced by the new Department of Foreign Affairs. The new department was new in name only and maintained its staff as well as responsibility for the same functions.[3] The old External Affairs title was sometimes causing confusion and the name change to Foreign Affairs, initiated by William McMahon, brought Australia into line with common international practice.[4]
Information about the department's functions and government funding allocation could be found in the Administrative Arrangements Orders, the annual Portfolio Budget Statements and in the department's annual reports.
