Australian Volunteers International
Lonely Planet review for Australian Volunteers International
Mainly involved in recruiting Australians to work overseas, but does also place skilled volunteers into Aboriginal communities in northern and central Australia. Most of the placements are paid contracts for a minimum of a year and you will need an appropriate work visa. There are, however, occasional short-term placements, especially in the medical or accounting fields, and short-term unskilled jobs, usually helping out at community-run roadhouses.
