Arno Bay local Cooper Llewelyn is continuing a new tradition of Eyre Peninsula leaders at his boarding school, Rostrevor College.
He has been named Head Boarder, replacing the outgoing Cameron Taheny of Cleve.
Camaraderie will be Cooper's main focus as he takes on the role in 2020.
"When a new student comes into the boarding house, it would be good to pair that student up with an older boarder who can mentor him," he said.
"I would like to bring everyone together a bit more as we have a lot of shared interests and have had similar life experiences."
School sport is a major interest Cooper shares with his peers, known as an all-rounder.
Playing for Ports Football Club as a junior and Port Neill Cricket Club when at home, Cooper is excelling at both in Adelaide, a member of the Rostrevor First XVII side and playing for Norwood U18s
He is wicket keeper for the school's First XI, has represented the EP in cricket four times and has put his experience at the Arno Bay squash court to good use, winning the school's Most Valuable Player award in the sport.
School principal Brian Schumacher said the 17-year-old was a "man for others."
"Cooper has a genuine interest in making new boarders feel welcome and a desire to build strong connections and friendships between all our boarders," Mr Schumacher said.
"He also has a great enthusiasm for so many sporting and educations pursuits that he will be a great role model for others."
