About our school
A Tradition of Excellence, A future of Opportunity
St Mary’s Cathedral College (SMCC) stands as a place where faith, learning and character unite. For two centuries, the College has nurtured students from across Sydney, offering a comprehensive education grounded in ¶¶ÒõÆÆ½â values & academic excellence.
Today, St Mary’s continues to evolve, now proudly offering a co-educational Kindergarten to Year 12 model across a dual-campus setting. This includes new state-of-the-art learning facilities on William Street. This expansion reflects our mission to provide a contemporary Liberal Arts education that blends tradition with innovation.
Proudly an award-winning school, St Mary’s Cathedral College was acclaimed in The Educator 5-Star Best Schools 2025 & among the Most Innovative schools in the nation. This excellence is embedded in our new three-tiered structure; Junior (K-4), Middle (5-8), and Senior (9-12), which supports each stage of a student’s journey with programs enriched by our unique city location and partnerships with leading cultural and educational institutions.
This approach drives outstanding academic results, including a top-150 HSC ranking in 2024, which are complemented by vibrant co-curricular achievements. From Model United Nations success to our first co-educational carnivals, our community values excellence in every pursuit.
At St Mary’s, faith & reason guide our students to think critically, act compassionately, and ultimately, lead confidently. We don’t just prepare them for the next step, we shape young people ready to make a meaningful impact in the world.
