Norma began her missionary work on Groote Eylandt, Northern Territory in 1952 with Judith Stokes. They lived in a bark hut built from local materials for nearly a decade and took charge of the Anglican mission school at Angurugu that had about sixty children in the school also several Aboriginal men and women helped with the teaching. She combined a pastoral ministry with her teaching responsibilities. Norma went to Umbakumba in 1964 to teach, returning to Angurugu in 1965 to start a pre-school which began in a tent before moving to a old school and finally to a new school building. She stopped teaching in 1969 to give herself to a full-time pastoral ministry where she prepared religious instruction and Sunday school lessons. With the exception of ten weeks at Ngukurr in 1975 and Oenpelli in 1984 she spent thirty-three years of religious service entirely on Groote Eylandt. In 1985 the Angurugu people gave Norma an incredible farewell. She was made a member of the general division of the Order of Australia for service in the field of Aboriginal welfare in 1980.,
