The Honourable Robert French AC

One Disease Patron

"Specific, targeted programs with a narrow focus which are not holistic but have contextual sensitivity may have flow-on results in other areas, and at least help to loosen the tangle of disadvantage. The One Disease organisation, whose present focus is the prevention and treatment of scabies in Aboriginal communities, is an example of that kind of program."

The Hon. Robert French AC has had significant involvement in Indigenous affairs, notably serving as the first President of the Native Title Tribunal. He was one of the founders of the Aboriginal Legal Service of Western Australia and served as Inaugural Chairman.
