Trinity provides a small Boarding House adjacent to the School for boys from rural Victoria, New South Wales and from overseas. The accommodation is in two houses, with senior boys in their own bedroom and younger boys usually sharing a room with a boy of similar age. The boarders live as a large family as in a Homestay with the resident House Master, his family and the Boarding House Tutor. There is domestic help for main meals, washing and cleaning, but boys are expected to help with some of the usual household chores including the washing up and room tidiness. Their sharing and support for each other is an important part of the culture of the Boarding House.

The Boarding House staff are also teachers at the school and they provide wonderful tutorial assistance in their subject areas. The proximity of the Boarding House to the school allows the boarders to use the pool, sports hall, Internet and Intranet as well as the music rehearsal areas or Science Design and Technology rooms. The boarders organise weekend activities, trips to the City or local shops and they can take the opportunity of interacting with the other Trinity boys and their families.

The Boarding House is home for the boys. All boarders are involved in normal school life including Sport, House Competitions, Music and Drama. They have the benefit of a wonderful home and easy access to all the School’s facilities.
