Castle Hill Campus

The Castle Hill Campus is at 84-88 Cecil Avenue, Castle Hill, conveniently close to the town centre. The school is tucked behind the church complex in a quiet and protected setting. Our Castle Hill campus caters for Kindergarten to Year 4, after which students move to our campus at North Kellyville for later year levels.  Spacious playing areas surround a well-designed set of classrooms and specialist learning spaces such as a computer laboratory, library and Early Learning Centre that caters for up to 59 children.

Kellyville Campus

The Kellyville campus is at 4 Gum Nut Cl, which is close to Samantha Riley Dr in a rapidly developing growth corridor in the North West of Sydney. The Kellyville campus commenced operating in 2011 and caters for Years 5-12 focusing on a Middle School (Years 5-8) and Senior School (Years 9-12) program.  A Junior School was commenced in 2018, offering Kindergarten and Year 1, with Year 2 to be added in 2020, and so on.  The campus has undertaken a substantial building program providing the College with state-of-the-art teaching and learning areas.
