St Joseph's College participates in an inter-school sporting competition. The summer and winter competitions run for eight weeks each. Training for swimming, cross country and athletics occurs in their respective seasons. Students are able to compete for selection in various sports for Darling Downs teams, and subsequently Queensland selection.

While sport is not for everyone, students are encouraged to participate each week to the best of their ability. Students are bussed to various locations and bussed back to the College in order to travel home via their normal route.
Term 1
Students are able to compete for selection in various Darling Downs teams from many sports in Under 15 and Open age divisions. They must attend a Toowoomba selection afternoon and once selected at this level compete at the Darling Downs selection day.
The College holds its annual swimming carnival at Toowoomba's Milne Bay Pool. The students swim according to their ages for age champion. From this event students are selected to represent the College at the inter-school swimming carnival. Students can also nominate to trial for Darling Downs selection.
Swimming training is held each morning for students who wish to learn how to swim and also for students who do not swim on a regular basis but would like to improve their chances in the pool.
The last week of term the College cross country is held at Kearneys Spring where students compete for age champion, with all points being tallied to determine the House championship.
Cross country training commences in the afternoons immediately after the swimming carnival is held.
Each Friday night the Friday Night Basketball Competition is run for students in Year 8, Under 15, and Open group divisions for both boys and girls.
Term 2
The winter sports tend to be those which are more aligned to community winter sports such as rugby league, soccer and touch.  If students do not make the various inter-school teams, they join a social sport activity each week.
Students may nominate to compete at the Darling Downs Cross Country event to be held at Kearneys Spring. Cross country training continues on nominated afternoons.
