Bathurst High Campus claimed a dramatic four-point victory over Orange High School in the Astley Cup on Friday.
Orange, the defending champions, had a decent lead going into the rugby league.
But a Bathurst 30-20 victory meant the boys high jump, which had been postponed from Thursday, was the deciding sport.
Bathurst principle Ken Barwick said the Astley Cup is a fantastic feature to the school.
“It add values to school and education. Not many schools get to experience a sports carnival at such an elite level,” he said.
“It’s a chance for students to showcase their talent in front of their peers.”
Mr Barwick said the Astley Cup, alongside with the performing and creative arts, is just some of the great assists Bathurst High have on offer.
“It highlights what we offer, that we have a broad education.
“Sport is a massive part of Australian culture and it is implemented in the early years at school.”
