BILL TURNER CUP⚽️| Congratulations to our Bill Turner Cup boys' football team who are through to the next round after defeating Hornsby High School on home soil today. ![]()
In a tight game, the score was 3-3 after 90 mins, meaning Golden Goal extra time. The result could have gone either way with both sides having a number of opportunities before our boys found the back of the net to claim victory. ![]()
Well done to all the boys and Super Coach, Ms Martin on an excellent performance, and thank you Hornsby High for a good game played in good spirits.![]()
