When Australia's last groups of nomads walked out of the desert, David Scrimgeour was the first doctor to examine them.
The Pintupi Nine emerged from the Gibson Desert in 1984, almost 200 years after European settlement began on the nation's east coast, and were thought to be the very last Aboriginal Australians to live as hunter-gatherers.
It turned out they were the second last. Two years later another family — known as the Richters — came out of the Great Victoria Desert, marking the end of a millennia-old chapter in the nation's history.
