The 11-year-old, who goes to Mueller College, won the graded division at the nationally-ranked tenpin bowling tournament earlier this month.
Dean, from Morayfield, beat Ballina bowler Sam Coombs 459-436 in the Restricted Final to land his first win, according to his father Charlie.
“As this was his first win he was not sure exactly what to feel,” he says, “but once he realised he had won, the excitement came and he was over the moon.
“It was great to see all that effort and training he does with (coach) Don Lindsay has paid off. For someone who is 11, to hold his nerve is a massive credit to him and his preparation.”
Katelin Melton, who is also based at Caboolture Bowl, won the BDP Rising Star Award, finishing fifth in the Open Division.
The 14-year-old was close to beating defending champion Jess Canfield in the quarter-finals of her first nationally-ranked event.
Her parents Alicia and Shayne said Katelin was “really shocked to be given this award and they were “extremely proud of her efforts”.
Katelin is now preparing for the sport’s national championships in Tasmania in July where she will try out for the Under 14 Junior Masters.
Jake Sayer, from Ballina, received The Fletcher Family trophy for Sportsmanship, donated by the Fletcher family from North Lakes.
