Jagamarra was born near Central Mt Stuart in the Willowra region in 1955. His traditional country is Wantapari, 60km west of Willowra in the Tanami Desert. He is the son of Minnie Napanangka, a Walpiri woman and Gerry Maloney, an Irish bushman. After attending Adelaide Boys School and enjoying a ten year career as an Australian Rules Footballer, he returned to Willowra. It was here that his Aboriginal education would begin. He passed through his initiation into manhood and was instructed in the sacred songs and body paint designs used in ceremony.
He began painting in 1985 under the tutelage of Willy Reilly Napanangka
since then his achievements have included his work appearing on Telstra Phonecards and his designs being made into rugs and a permanent mosaic piece on the floor of Ujazdowski Castle in Poland. He has travelled extensively throughout the world and his paintings form part of many private and public collections.
