Each student is placed into a House when he commences at the college.
Throughout the year the four houses compete in various activities including swimming, athletics, cross country for the Michael Carmody Cup. These competitions enable students to develop team spirit and build camaraderie across year levels in sporting, academic and cultural pursuits.
The Houses are named after early Archbishops of Melbourne. The four Houses are:
Polding (red) Archbishop John Bede Polding first arrived in Australia on 13 September 1835. He was appointed Vicar Apostolic with jurisdiction over what is now the Commonwealth of Australia.
Mannix (blue) Archbishop Daniel Mannix was the Archbishop of Melbourne for 45 years and made his name with the Conscription issue during World War One. Twice he confronted the Prime Minister, William Hughes, on this matter, and with the help of the troops on the Western Front in Europe, defeated the Conscription Bill.
Knox (green) Archbishop Robert James Knox was appointed as the fifth Archbishop of Melbourne,
serving between 1967 and 1974. He saw education as pivotal and proposed one central theological college, rather than separate seminaries for diocesan priests and those of religious institutes.
Goold (gold) Archbishop James Goold helped to restore order and calm on the gold fields of Victoria and saw the need for school buildings within the Melbourne area.
