Bethany College has excellent opportunities for participation and representation in a range of sports. The college is a participating member of the Catholic Girls Secondary Schools Sports Association (CGSSSA) and the Sydney Catholic Colleges Sports Association (SCC). This provides elite athletes with the opportunity of representation at regional, state and national competitions.
The college sports program runs on Thursday afternoons throughout the year for students in Years 7–10. This is divided into two categories: weekly representative competition and recreational sports activities. Students who wish to compete in the weekly representative competition attend a try-out session and, if successful, compete against other member schools of the SCC.
Students involved in the recreational program select a different activity for each term. All students from Years 7–10 participate in swimming, gym and team sports.
The college also competes in gala day representative events in the following sports:
