GoKawiilIn 1984 a group of Australian Aboriginal people living a traditional nomadic life were encountered in the heart of the Gibson desert in Western Australia. They had been unaware of the arrival of Europeans on the continent, let alone cars - or even clothes.
If you want to know how Australian Aboriginal peoples lived for 40,000 years, just ask Yukultji. She stepped into the 20th Century just 30 years ago. She is the youngest member of the Pintupi Nine, the last family of nomads to roam the territory around Lake Mackay, a vast glistening salt lake spanning 3,500 sq km (1,350 sq miles) between the Gibson and Great Sandy deserts of Western Australia.
"When I was young I would play on the sand dune and when we saw the old people returning to camp we would go back and see what food they had brought with them. After we ate we'd go to sleep. No blanket, we would sleep on the ground," says Yukultji.
"Then we would go to another waterhole and make another camp."
Before 1984, the Pintupi Nine lived just as their ancestors had done. Waterholes in this area are often 40km (25 miles) apart or more, and every day was spent walking in the relentless heat from one to another. "Sometimes there was no water, so we would hunt for goanna," says Yukultji. The blood of these monitor lizards provided vital moisture when a water soak was dry.
