The compulsory programmes for each year group are as follows:

  • Year 7 – Peer Support Induction Programme.
  • Year 8 – Either an auditioned Music group or the School’s Cadet Unit.
  • Year 9 – one of the following: auditioned Music group, Cadet Unit, community Service, Debating, Duke of Edinburgh Bronze programme, Drama Production, or Chess.
  • Year 11 – Peer Support training to develop vital leadership, decision-making and communication skills.

From Year 10, students undertake at least one ‘secondary’ Co-curricular activity in addition to any compulsory activities.

Inspiring co-operation and mutual respect, competitiveness is encouraged for the sake of students giving their best, rather than for the sake of winning. From Year 7, all students are required to participate in a Summer and a Winter sport which involves mid-week training and a Saturday commitment of inter-school competitions, under the authority of the Combined Associated Schools (CAS).

Coaching is provided by members of staff, external coaches, and specialist personnel. Testimony to the value of these programmes is the School’s history of success across all sports.

Basketball | Years 7 – 12

Basketball at Trinity has become one of the sports with the highest participation in the School. Over the three campuses there are 60 teams playing basketball! Development Tours to the US occur every three years and Trinity has been fortunate to see numerous players go on to be selected in elite teams.

Cricket | Years 7 – 12

Cricket at Trinity is open to all students of all levels of ability. The team sport helps to build an appreciation of the need to perform at one’s best for the benefit of the team and it helps students to develop confidence in team situations, building solid friendships along the way. Trinity boasts 18 cricket teams in the Senior School. Students have the opportunity to tour internationally once every two years.


Fencing | Years 11 & 12

Of the three Fencing codes, Trinity students learn to fence with the foil: a short blade descended from the smallsword of the 17th and 18th centuries. Unlike other solo competitions, Fencing places less emphasis on endurance and the ability to move quickly for long periods. Instead, foil fencing is akin to chess, where the competition is determined by preparation during the bout and in reading one’s opponent rather than in the execution of an attack.

Golf | Years 10 – 12

This Co-curricular activity provides an opportunity for students who are already involved in the sport to further develop their skills and understanding of the game. It is open to those who have an AGU Handicap or are part of a Cadet Programme through their local Gold Club. There is also an Interschools Golf Series Competition that students participate in.

The Cadet Unit is an Adventure Training and Leadership activity. During Cadets, students will learn to lead and take responsibility for each other and learn to follow and respond to the leadership of students. The activity offers a wide variety of training to care for many interests that include signals, survival and first aid courses, navigation, and officer training. In a partnership with Meriden School, students from both schools work together, cooperating and collaborating towards shared goals, as is the situation in after school life. The School utilises a relationship with the Australian Army to access a variety of different military training areas for its field phases activities.

In Senior years, students can take courses in Leadership Training to prepare for various positions of responsibility within the Unit. Specialist platoons cater to those boys who wish to continue to serve the Unit in a non-leadership capacity but remain within the activity.

If you would like to know more about Trinity’s Cadet Unit, or have questions regarding your son’s involvement, please get in touch with Ms Susan Draysey.
