Billy Yaluwangka was born in 1952 and was one of 25 children whose father was the remarkable indigenous painter Mandark — a man who refused to be drawn off his country and into the assimilationist “settlements” of Arnhem Land. Billy drew from a deep well of indigenous knowledge of matters spiritual and physical, tutored by his father and the old man’s four wives. When I took these photos in 1979 the family was living in bark shelters south of Maningrida at a place called Birba. Billy and his wife Brenda followed tradition and the inside of their bark house was covered in simple but powerful paintings executed with white clay and charcoal on the stringybark sheets. Foolishly, at the time, I didn’t ask Billy to identify all the subjects in his paintings. However, when I look carefully at them now, I am sure one is of a wallaby that hasn’t been seen for several decades and may well be locally extinct. The wallaby is Wularla, the spectacled hare wallaby (Lagorchestes conspicullatus) which has a circle of orange fur around it’s eyes — a very clear diagnostic. The birdwatcher in the family (Jan) believes the bird at the bottom to be a peregrine falcon. Sadly, I can’t ask Billy. He died about 10 years ago.
