Helen Plummer Phillips (1850–1929) educator, missionary, philanthropist, was the first missionary sent from Australia by the newly formed Church Missionary Association NSW (now CMS Australia) in 1892. She was the first tutor for women students at the University of Sydney and formed the University of Sydney Women's Society in 1891 and established its settlement work, mentoring the women students until the Women's College was built and the first principal arrived. Phillips was a principal of St. Catherine's School, Waverley NSW, an advocate for women's full education, and a benefactor of St Luke's Anglican Community Church, Medlow Bath, NSW.
