In addition, there are approximately 1,200 small Indigenous communities, of which almost half have a population of fewer than 100 people. The Royal Flying Doctor Service (RFDS) started service in 1928 and helps people who live in the outback of Australia. In former times, serious injuries or illnesses often meant death due to the lack of proper medical facilities and trained personnel.
