BBC Swimming is focused on the preparation of students in Years 5 to 12 who wish to represent the school at the GPS Swimming Championships. The program also welcomes students who wish to gain fitness, flexibility and strength for their respective sports and are prepared to swim competitively for the College.

Pre-season begins in Term 4 and includes weekly lead-up meets which culminate at the GPS Swimming Championships held in Term 1. Swimmers from Years 5 to 12 compete in Age groups for the Senior GPS Competition (13 Years & Under to Open) and Junior GPS competition (10 Years & Under to 12 Years & Under). BBC Swimming enjoys a strong partnership with UQ Swim Club.
