Every lunchtime Billy Johnstone heads for the gymnasium at Western Heights High School for a game of volleyball.
It is simply a tradition.
And every day he is joined by a large number of other keen volleyball players, most of whom were introduced to the sport on arriving at Western Heights.
Billy, 15, said since he started at Western Heights in Year 9, volleyball had always been a big part of school life.
"It is part of the school culture really, and I have always been apart of it. It is a tradition," he said. "Every single lunch we come and play. I have never missed one yet ... unless I am studying."
