Ms Kelly, whose work has been the subject of three documentaries, began her humanitarian career at a young age. Born in Melbourne in 1964, she worked with Aboriginal children in Western Australia at the age of 20 and then alongside Mother Theresa in Calcutta two years later.

Her projects since then have included working with AIDS sufferers in Australia and Kalahari bushman in Botswana, and assisting the sick in South Africa, the United States, Romania, Bosnia and Albania.
