For the purpose of Welfare Branch field administration relating to aborigines, the Northern Territory was divided into districts. Between 1957/58 and 1961/62 there were four districts reporting direct to the Welfare Branch.1
In 1961/62, field operations were divided into northern and southern divisions. The District Welfare Office, Lindsay District (CA 2844), based in Tennant Creek, and the District Welfare Office, Giles District, based in Alice Springs reported to the Divisional Welfare Office (Southern) based in Alice Springs, which in turn reported to the Welfare Branch (CA 1076) in Darwin.2
The Divisional Welfare Office (Southern) and the District Welfare Office, Giles District, shared the same office accommodation. In 1967/68, the Warburton District was created (? from part of the Giles District).3 The District Welfare Officer, Warburton District shared accommodation with the Giles District and Divisional Welfare Office (Southern) staff in Alice Springs.
In about 1970 the area of operation of the Giles District was: Docker River
Maryvale
Angus Downs
Papunya
Haasts Bluff
Areyonga
Finke
and the area of operation of the Warburton District was:
Amoonguna

The administrative history of the agency in the early 1970s is subject to further research. The functions of the agency may have passed to the Department of Aboriginal Affairs, Regional Office, Alice Springs (Northern Territory) (CA 2602).
