Nine Pintupi family roamed Gibson Desert traditionally until 1984. Unaware of European colonization or modern Australia. Two co-wives and seven teens survived on goanna, rabbit, bush foods. Armed with spears, boomerangs, hairstring belts. Father died prompting south trek toward smokes. Fled shotgun-wielding campers in misunderstanding. Relatives tracked and found them after 20-year separation. Astounded by piped water and abundant food. Medically perfect: no fat, strong, fit, healthy. Piyiti returned to desert life in 1986. Three brothers became famous Tjapaltjarri artists. Three sisters renowned Aboriginal artists. One mother died – other settled with daughters. Not true last nomads – Richter family found in 1986.
