Housed in a modern, purpose-built facility, the Junior School is adjacent to the Middle and Senior campuses, meaning our pupils can interact with the varied activities at the Senior School.

Mr. Mark Dunn

Head of the Junior School

On any typical day, a Junior School boy has the chance to attend a high school maths or science club, watch a Cadet parade, observe a training session of the Sydney Kings basketball team in the Sports Centre, play with the full Symphony Orchestra or worship in the War Memorial Chapel.

Boys and teachers are excited to come here each day. It is a place of great friendship where every boy will find things they enjoy. For all of us here, Mind, Body and Spirit is more than a slogan. We are helping boys catch the excitement of learning, discovering God’s purpose for them and helping them grow into it.

The Junior School is a campus that grows as the boys grow, with new boys joining throughout the journey, especially at Years 3 and 5. Offering the International Baccalaureate Primary Years Programme (PYP), we guide boys to become independent, inquiring learners. Most of all, we encourage each boy’s ownership of his learning, developing research and critical thinking skills that will accompany them through their journey at Trinity and into their adult life.

We are extremely fortunate to have a close-knit and supportive school and parent community and endeavour to maintain a strong connection between school and home.

We would be delighted to show you around the Junior School so you can experience for yourself the friendly and supportive atmosphere that underpins all we do – please contact our enrolments team to arrange a visit. You can also find information about joining the Junior School here.
