Gillespie will commence his new role with the Redbacks following the conclusion of the English county season, where he is currently coach of Sussex.
The former Australia fast bowler will continue coaching the Strikers, with the season set to begin on December 3.
“I’m deeply honoured to be afforded the opportunity to coach the South Australian cricket team,” Gillespie said.
“The chance to work with the players, coaches and off field team at the SACA is very exciting.
“Team SACA is something I’m very much looking forward to being a part of.
“I’m very excited!”
Gillespie led the Strikers to their maiden KFC Big Bash Championship in KFC BBL|07, and can only benefit further from a year-round presence in the system.
SACA CEO Keith Bradshaw is delighted with the appointment:
“The men’s head coaching role is the most important in South Australian cricket, and we know that Jason is the right person to invigorate our program and push it forward,” Bradshaw said.
“He is a proud South Australian with a phenomenal coaching resume behind him, we have seen how he has worked with the Strikers, leading them to their first title, and I know Jason will give it his all to steer the Redbacks in the right direction.
“We acknowledge that Jason will be in England until October as he is committed to his role with Sussex until the end of their season.
“This is one of the reasons we are delighted to have Jason on board. He is a quality person, once he starts something he is fully committed.”
