“Choosing St Mary's is the best decision we could have made. My daughters are both happy and thriving. Their love of learning is encouraged and fostered. Every day on our journey home I listen to my daughters chatting excitedly and enthusiastically about what they have learned each day.”
Parent survey
“St Mary’s enables its girls and young women to stand out from the crowd. They are confident, caring and positive. However, most of all [my daughter] leaves St Mary's with the knowledge that to get on in the world, she can shine without it being at the expense of others. I certainly feel the whole school nurtured Emily to know that: 'She Can!' ”
Parent
“St Mary’s opens girls’ minds to the world, to have not only knowledge and understanding of it, but to be able to reflect upon culture and society and to contribute significantly to it.”
Rachel Gleeson, Alumna
“We are delighted with the school. Our daughter is very well cared for and the staff teach excellently. She is achieving excellent academic results and blossoming in a loving community.”
