In 1983, the Archdiocese purchased seven hectares in Bonnyrigg Heights, which would become a site for a parish church and for a regional secondary school to serve the parishes of Mt Pritchard, Horsley Park, Bonnyrigg and Bossley Park. Cardinal Freeman officially opened Stage 1 of the school on 30 June 1985. The new school began in six demountable classrooms with 105 students and 9 teachers. Today, the school is a well-resourced college with modern facilities catering for the needs of 1300 students and a teaching and support staff of 114.
