Welcome to St Leo’s Catholic College, Wahroonga
Est. 1956
St Leo’s Catholic College is located on six hectares in the leafy suburb of Wahroonga and is the
only co-educational Catholic secondary school on Sydney’s Upper North Shore.
We are a caring, inclusive community renowned for our pastoral care, with a strong emphasis on knowing each student and growing their unique potential.
With consistently strong academic results and a wide range of co-curricular offerings, we aim to help students
find their passion and develop their talents so that they can shape and change the world for the better.
In 2026, we are proud to be celebrating 70 years. A special 70th Anniversary Mass was held in February, and a ‘Back to Leo’s Day’ will be held in November.
All welcome. Watch this website or follow our Facebook page for more information throughout 2026.
St Leo’s acknowledges the Darug and Guringai people, the traditional custodians of the lands in Wahroonga on which we learn.
