Dallas was born in Halls Creek in 1969. His mother was Kija and his father a Jaru man from the Halls Creek area.

He was schooled in Broome and South Hedland then after some  time living at Ardiyallon/One Arm Point, Dallas returned to Halls Creek.

Dallas paints in the Yarliyil studio regularly, but unlike his fellow artists whose paintings are depictions of culture and country, Dallas paints as a means to express wider political and societal themes that affect Aboriginal people.

Dallas explores human rights abuses and injustices as well as societal concerns such as the use and misuse of AI and human data.
