Both of Sandra Miller's parents were removed to Koonibba Mission where she was born. Miller worked for many years in the Department of Community Welfare in South Australia providing support to members who were affected by separation.
Miller's story was recorded by the National Library of Australia for the Bringing Them Home oral history project and appeared in the associated publication Many Voices: Reflections on experiences of Indigenous child separation, edited by Doreen Mellor and Anna Haebich (2002).
