The Sisters of St. Basil the Great trace their origins to 4th-century monasticism inspired by St. Basil and his family. Their modern U.S. history began in 1911 with four Sisters arriving in Philadelphia. By 1921, they founded the Our Lady of Perpetual Help Province in Cleveland, caring for orphans and expanding educational ministries.

After acquiring Mount St. Macrina in 1933, the estate became their permanent motherhouse and ministry center, hosting spiritual retreats, schools, and care facilities. 

They expanded services to include pastoral care, iconography, and substance abuse rehabilitation. Despite challenges like the Great Depression, the Sisters remained committed to their mission as a praying, healing, and life-giving presence. Today, they continue this legacy while preparing to pass stewardship to future generations.

They began their ministry among the Ukrainian faithful, establishing monasteries in Melbourne (1970) and Adelaide (1977). Today, they continue their mission in North Melbourne and Sydney. Rooted in prayer and dedication, their apostolate includes catechesis, sacramental preparation, youth choirs, daycare, pastoral care for the elderly, and preserving Ukrainian traditions.

Their service helps maintain the Byzantine Catholic faith and cultural identity of Ukrainian families in Australia. Through decades of quiet, faithful work, the Basilian Sisters have profoundly influenced generations, nurturing spiritual life and community within both the Ukrainian and wider Australian society.
