Holy Cross College offers a varied sporting programme with a focus on participation, as well as the opportunity for students to compete at a range of levels. Lightning carnivals and Inter-House competitions provide opportunities for high levels of participation in a range of sports.
Middle and Senior School students are able to participate in afterschool sport through the College NEAS (North Eastern Associated Schools) sports programme. Students can play against other schools in basketball, netball, frisbee and soccer.
All students participate in Inter-House sporting carnivals in swimming, cross-country and athletics. From these events, squads are selected to represent the College by participating in inter-school competitions at the Catholic Primary Schools Sporting Association (CPSSA) for Junior School students, Associated and Catholic Colleges (ACC) carnivals and the WA All Schools Cross-country Carnival for Middle and Senior School students.
