Nyunjarn Charlie Nunjun was born at Mulu jila, also called Nyarnjarnkurra, south-west of Kurtul in the Great Sandy Desert, Western Australia. His family was living all over, at Jigalong, Cotton Creek, Well 33 on the Canning Stock Route and Punmu. His father came from Yimirri country, the other side of Nupawarla. His mother's country was Karligangku, east of Well 31 on the Canning Stock Route.
When he was a young man, Nyunjarn and some of his family left his country, Nyarnjarnkurra. They travelled to Kaningarra where, from the top of the hill, they saw their first car. Some of the family didn't want to leave their country so they stayed behind. Later on they moved to Jigalong, Cotton Creek, Well 33 and Punmu.
When Nyunjarn came from the bush he worked at Chestnut Bore but he could only speak Wangkajunga language. He learnt Walmajarri and station work the hard way.
Nyunjarn began to paint on canvas in 2001?02. He advised some of the artists who contributed to the collaborative Ngurrarra canvas but did not paint until a cataract operation. His work was first exhibited at Raft Art Space, Darwin in 2003.
