Discovering her best
We provide girls with opportunities to pursue personal and academic excellence in a respectful and supportive environment. We want our girls to be self-aware, adaptable learners who are immersed in the exploration of ideas and embrace challenges with grit and integrity. Simply put, we help our students discover their best.
LEARNING
Igniting curious minds
For more than 100 years, St Mary’s has helped girls reach their academic potential. Our students are renowned for achieving academic excellence and enjoying success in their lives after school. Our dedicated staff are invested in each girl’s education and are committed to engaging hearts and igniting curious minds.


BOARDING
A home away from home
St Mary’s has been home to thousands of boarders over the past 85 years. Our boarding house is at the heart of our Karrinyup campus, both in location and sentiment, and our staff pride themselves on understanding the needs of country girls. Parents can rest assured knowing that their daughter will have every opportunity to discover her best in a safe, supportive environment.
