The fast bowler was selected following a notable showing on tour in Pretoria earlier this year.
The trip to down under will suit as a fitting ending to a largely successful sporting year for the spin-turned-fast-bowler.
Apart from the selection, Groenewald also bagged a bronze medal for discus at the South African Athletics Championships at the Free State Stadium earlier this year.
He also starred in shot-put where he just missed the podium by a solo position, finishing fourth.
The Melbourne schools cricket jamboree will run from December 10 to 17.
Groenewald made his bow in the game as a spin bowler in grade six before discovering his fast-bowling prowess.
His point of reference in the gentleman’s game is Dale Steyn, citing the Phalaborwa Express’s fighting instinct and professionalism.
Groenewald, however, who’s also a member of his school’s first cricket team, will unfortunately not be travelling to Australasia, citing the expenses involved in the trip. – @SabeloBoksburg
