Colleen is a self-taught artist who comes from a strong family tradition of Eastern Arrernte painters, including Therese Wallace (Colleen's mother) and Gabriella Wallace (Colleen's aunt). Colleen was raised by her stepmother, Kathleen Wallace, at Santa Teresa and Alice Springs. Colleen's father's country is near Gem Tree, north east of Alice Springs.
Colleen's most popular paintings illustrate Dreamtime Sisters who are good spirits dancing the awelye (women's ceremony) and looking after Colleen's country.
'My country is called Arnumarra that is my grandfather's country. In my painting, the dreamtime sisters are a group of spirits that look after the land and also their role is to guard special areas such as sacred sites and protect the land.' ? Colleen Wallace, August 2014.
Colleen says these sisters were once living people; her ancestors. She also paints Awelye (Women's Ceremony) and Arlatyeye (Bush Yam Dreaming).
Colleen now lives at Mulga Bore (north east of Alice Springs) and Alice Springs with her husband, Colin Bird (Ada Bird's son) and their children. Colleen also works at Mulga Bore School as a teacher.
