Members of the MSB Equestrian Club wishing to compete in equestrian events are required to have their own horse and arrange to undertake suitable training through Pony Clubs or private tuition. The students involved in the Equestrian Club are able to enter events open to schools such as the NSW Interschool Championships.

The Equestrian Club holds regular lunchtime meetings, which are open to all students to attend who have an interest in horses. Students do not need to have their own horse to attend these club meetings.
