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. There will be public events in February (Mass) and October (‘Back to Leo’s Day’). All welcome. Watch this website or follow our Facebook page for more information early in 2026.
