The Ambrose Treacy Centre is a multi-use venue for sporting, educational and business purposes, overlooking College sporting fields to the Mt Barmoya vista. A fully equipped gymnasium, basketball, netball, futsal, volleyball, handball and badminton courts, and space for Physical Education classes secure its sporting use, inclusive of after-hours extra-curricular activities. A boardroom, multiple classrooms, and staff offices make provision for educational use, while a mini art gallery and school archive contribute to showcasing the College and its provenance when the Centre is used for a variety of events throughout the year.
