Water Polo is a vibrant part of the St Augustine's summer sporting program. It teaches the boys about teamwork and good sportsmanship, encompassing and strengthening the ideals of community in the Augustinian community.

The student can build strong and lasting relationships with boys from different years and social groups. Our senior boys set an exemplary standard to the younger boys by taking an active and a responsible role in Water Polo and by leading with example. In addition, they take on coaching roles and set high standards where the younger boys look up to and aspire to.
