The 23-year-old right-hander debuted for the Strikers in the opening match of BBL|04, playing a total of eighteen matches for the club.
SACA High Performance Manager Tim Nielsen acknowledged the decision was disappointing for the Strikers and their fans.
“It’s unfortunate news for us and Strikers fans because Alex has enjoyed an exciting BBL with the Strikers last season,” he said.
“We did our best to retain his services for the Strikers, but in this instance he’s decided to take on a new challenge with a different franchise.
“We’ll continue to look at our list over the next few months and will focus on putting together the best possible squad for BBL|06.”
