Trinity College is an independent day school for boys, located on the Swan River foreshore in East Perth, Western Australia. The school was established in 1962 when students from the city schools CBC Perth and St Patrick's Boys School moved to the new Trinity College campus.^[1][7]

Trinity College is commonly shortened to Trinity or TC. Former students of Trinity are called Trinity Old Boys. Trinity is a school in the Edmund Rice tradition promoting classic and modern education, culture, dance, drama, music, service to others, spirituality, sport, and vocation.^[5] Trinity comprises an East Perth campus with a junior school for Years 4 to 6, a middle school for Years 7 to 8, and a senior school for Years 9 to 12; an outdoor education wilderness at Camp Kelly Dwellingup; and sporting grounds at Waterford.

The college has undergone significant expansion. The original 1962 buildings included Trinity Chapel, A and B blocks, Gibney Hall, the pavilion, a squash and handball court (both demolished late 1999), and the Brothers' Monastery (rebuilt into the Junior School in 1991). In 1983, Gibney Hall was widened, by bricking-in the balcony on the western side, and lengthened to accommodate all students and staff at assemblies. Over the years the college has expanded to include Kelly Senior School 1968, Duffy Library 1979, admin block 1981, Foley Physical Education Centre 1992, Treacy Design and Technology Centre 2001, Brockwell Observatory 2001, Curtis Aquatic Centre 2004, and O'Doherty Cultural Education Centre 2010. In addition to the East Perth campus, the school has Camp Kelly, an outdoor education facility situated 8 km south of Dwellingup, and 10 hectares (100,000 m²) of sports ground at Waterford.

Brother Kelly was the last headmaster of CBC Perth and the founding headmaster of Trinity College. He was headmaster during 1962-1966 and he returned again as headmaster during 1978–1984. Four Christian Brothers served as headmaster of the college. Over the years, lay teachers gradually replaced Christian Brothers on staff. In 1994, Anthony Curtis was appointed the first lay principal (name changed from headmaster to principal). Shortly after his retirement the school aquatic complex was named in his honour.^[11]

Trinity joined the PSA in 1968 and since 1969 Trinity has competed in all PSA sports. It is compulsory for each student to compete in a summer and a winter sport. In football, Trinity students typically do not compete for selection for the Western Australian Football League colts or for Teal Cup teams. This does not hamper future selection opportunities for students. Many students have been selected in the Australian Football League national draft based on their performance in the PSA. The sporting skills, coaching, fitness and organisation of students from the seven PSA schools is commensurable to the highest levels offered by any schoolboy competition in Western Australia. This is evident by the number of former PSA students who compete in their chosen sports at state, national, international, and Olympic levels.

As the most recent school in the PSA, Trinity has improved over time and the college has moved up the ranks in most sports. The most notable exception is swimming.

The main campus at East Perth has one oval which prior to the EPRA land-swap catered for a turf cricket ground in summer, a football oval in winter, and an athletics training track in spring. There are four outdoor hardcourts marked for tennis and basketball. The campus has a 50m swimming pool and a gymnasium which is marked with basketball, volleyball, and badminton courts. As well, the school has a rowing boathouse on the East Perth foreshore. Courses along Heirisson Island, the Swan River foreshore, and Kings Park including Jacobs Ladder provide excellent cross-country tracks. The East Perth campus lacks dedicated facilities for hockey, rugby and soccer. At various times the college has sought to purchase the land between the college and the Causeway, as well as vacant land on the north side of Gloucester Park. Negotiations for these purchases with the City of Perth have repeatedly fallen through due to town planning intentions. However, the City of Perth has allowed the college to use facilities at Haig Park, which has now been redeveloped by EPRA, and to use facilities at Langley Park and Wellington Square.

The Waterford playing fields have five cricket ovals, three turfed and two synthetic pitches. Two turfed pitch ovals become football ovals in winter and the remaining pitches separate into two soccer fields, two hockey fields and one rugby field.

The senior school holds official college trials and championships for swimming and athletics. Students who advance from the trials compete against each other in the college championships to decide school champions and to decide who qualifies for events on the school teams. Summer and winter team sports hold similar selection procedures relevant to the criteria set-down by each code. College champions for summer and winter team sports are chosen by judging committees who award points for a player's performance for each official PSA fixture. In addition, the college has three major sports awards. The J P Ilich Award for outstanding service to the school in sport, and the Old Boys Awards for the students who score the most points for Trinity at PSA athletics and swimming carnivals.

Trinity inherited a four house system from CBC Perth. Each house has a major and a minor colour, a motto and an emblem. Each classroom stream is divided into one of the four houses. Siblings and cousins belong to the house of their eldest relative. When played, competitions are held to decide the House Champion. Currently, the house system is the format for carnival competitions held within the junior school.

In 1979 the senior school replaced the four house system with a three carnival competition, House of Cards, held by students in the same year. Two carnivals, swimming and athletics, are called the Bowers, and the third carnival, cross-country, is called the Sevens. Teams are the same as the home-room class. In the lead up to the swimming and athletics carnivals, each home-room class holds an impromptu meeting to decide the Jack (class captain) and the Dealer (class selector). The tactics of the Dealer are the key to winning a Bowers carnival. Each student must compete in one of the race divisions for each event and the line-ups must be submitted before a Bowers carnival begins. Each race division awards the same points descending from first to last. Calculations using intelligence gathering and misinformation are required to work out the best order to race classmates. One important play is the Jack who is awarded maximum points regardless of where he finishes in a race. Cheating is a permitted tactic. A cheat stands and points awarded if no appeal is made to the carnival judge before the end of a race. If an appeal for cheating is upheld, the cheater forfeits points earned from the race. The winning team is the class which out-trumps the other classes by setting up the most favourable mis-matches in order to score the most points. The cross-country carnival, called the Sevens, is pure in format. No cheats are permitted and the carnival judge may order a cheater to wear a smock-of-shame for a day. The winning team is the first to have seven classmates cross the finishing line. However, there is one important exception. The team with the last seven to cross the finishing line automatically loses. The carnivals may be used for fundraising and nominal wagers by each competitor are put into a kitty. The winning team for each carnival is awarded the right to choose an approved cause to donate the kitty.

The title of the school hymn, "In Nomine Domini", is derived from the school motto and Psalm 123: adjutorium nostrum in Nomine Domini, "Our help is in the name of the Lord." The hymn was written in 1979 by Father Paul Keyte, the school chaplain at the time. Inspired by the Harrow School Song "Forty Years On", Father Keyte wrote in the 1979 School Annual, he was not merely trying to write a hymn but an anthem and something that, "would not only renew loyalty to the school but would also rekindle the flame of faith". The music was written by Brother Gerald Crooks, a long serving music teacher at the college. In 1984, Brother Crooks introduced a brass fanfare lead featuring trumpets and trombones. "In Nomine Domine" is sung at Speech Nights, Year 12 Graduations, Anzac Day ceremonies, and at PSA sporting events.

In November 2020 two former teachers were convicted of failing to report suspected child sexual abuse. The incident occurred on a Trinity rugby trip to Japan in 2017. The teachers, Ian Francis Hailes and Anthony Paul Webb, were said to be the first people convicted under WA's mandatory reporting of sexual abuse laws.^[34]

The alleged victim told a court he was bullied throughout the trip including being forced face-down onto a bed by Trinity teammates, his pants pulled down and sexually assaulted with a carrot. The alleged victim said the incident was raised at a "fines session".^[35]

The court found the teachers formed a reasonable belief on the rugby tour that sexual abuse might have occurred, but did not report it, as required by law.^[34]
