The Aquinas College Senior School focuses on the final years of secondary schooling from Year 10 to Year 12. Students are able to choose between a diversity of courses appropriate for their interests. These include the ability to gain university entry through to a vibrant INSTEP.

Boys are challenged to be the best they can be through their academic studies and are supported by staff who engage with them to achieve their own excellence.
Through the Senior School, boys are able to access Career Counselling so that they are setting achievable and realistic outcomes for themselves.

Through the Senior School, boys take on leadership roles and are able to develop their talents across a wide range of opportunities from music, drama, sport and service. This is complemented by outstanding retreats so that boys can develop into good men, knowing who they are.
