Senior School

Welcome to our Senior School

In our dynamic, supportive school community, every girl is known, valued and inspired. Founded in 1898, we offer an education built for girls, that allows their intellectual and social confidence to flourish.

A St Mary’s girl is known for her confidence and curiosity, her community spirit, her agile mind, her resilience and drive. Our approach to learning empowers girls to aim high in life, to follow their dreams and to make a positive contribution to society.
