The Arnhem Land reserve, closer to Bali than Sydney, covers an area of around 97,000 sq kms (37,000 sq miles), has a population of around 16,000 and access for non-Aborigines is by invitation only. Australia's aborigines are the custodians of the longest unbroken cultural tradition on earth, having migrated Down Under from Africa via Asia between 40,000 and 60,000 years ago, and connection to the land is practically written into their DNA.
