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 Catholic 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.
St Mary’s Cathedral College Sydney is a dual-campus, K-12 coeducational school in the heart of the city. We are committed to helping every student reach their full potential through a contemporary Liberal Arts approach. Our innovative curriculum challenges and inspires students to be independent, creative, and critical thinkers who apply learning to real-world situations.
Located in Sydney’s CBD, students benefit from unparalleled access to cultural institutions. As a world-class chorister school, music and the arts are celebrated. The Cathedral backdrop inspires students to deepen their Catholic faith. We hope every student’s journey is one of happiness, hope, and excitement.
