Aquinas inherited the college colours red and black as well as the PSA honours held by CBC Perth.

[10] Weekly sports fixtures occur during the summer months in basketball, cricket, tennis, volleyball and water polo, with Term 1 Competitions composed of six Rounds (Each School plays each other once), and a smaller Term 4 Competition (three or four rounds).

[11] Winter fixtures include Australian rules football, badminton, cross country running, hockey, rugby union, and soccer, and are played over 10 rounds (each school plays each other once, & 4 schools twice).

With the entry of Trinity in 1968, there have been several experiments with the seven school fixtures, including the current system, one round plus finals.

The carnival was held annually at the WACA Ground in East Perth until 1963, when it moved to the Stadium at Perry Lakes which had been built for the Commonwealth Games of 1962 in Floreat, but is now held at the Western Australian Athletics Stadium.

This victory meant Aquinas had won the athletics carnival more times than the other six schools combined.

[12] Basketball became an official PSA sport in 1980, the Blackwood Cup was introduced in the same year to commemorate the long service to Christ Church Grammar School and the PSA of Mr A F Blackwood, Deputy Headmaster from 1966 to 1983.

Originally, the Darlot Cup was awarded for seasonal competition (October to March).

[1] The competition, which is played on Friday afternoons and all day Saturdays, is a round robin tournament lasting seven weeks during first term, with every team playing each of its six opposition teams once and having one bye per season.

The team on top of the table at the end of the round is crowned the champion and is awarded the Darlot Cup for the year.

Bonus points are awarded for every run scored while batting and for every wicket taken while bowling.

In 2007 Trinity College ended Aquinas College's two year winning streak by achieving an undefeated season; in other words, they won their six races and finished first in the four all-schools events.

[12] In 2003, the Hockey Cup was renamed the Ray House Hockey Cup in honour of Mr. Ray House for long service to the PSA as delegate and Deputy Headmaster of Christ Church Grammar School.

[2] The team that finishes the 10 Match season on top of the Premiership Ladder is awarded the Ray House Hockey Cup.

Teams are awarded points as such, and ranked by the number of points achieved: On the final day of the rowing season, all PSA Schools attend the Head of the River rowing regatta, the First VIII crews from all of the schools compete for the Head Of The River title.

Hamer Cup was introduced in 1983, and is awarded to the school which scores the highest aggregate points in rowing at the Head of the River.

[2] Rugby became a PSA Sport in 1961, and in 1963 the Rugby cup was renamed the Brother Redmond Cup, in honor of Brother M F Redmond, who was an influential teacher and sportsmaster at Aquinas College over a span of 45 years.

The Ray Gamble Trophy, is the competition that takes place during Term 4 of each school year.
