Clarke, who had a long career as a solicitor after playing grade cricket in Adelaide for Glenelg, also served as a director with the South Australian Cricket Association for 21 years and was made an Honorary Life Member of the SACA in 2012.

"Jack was an outstanding contributor to Australian, South Australian and international cricket in his major roles with Cricket Australia and the SACA, and much-loved by all who knew him across the game," current CA chair Mike Baird said.

"Jack's leadership in vital areas including governance and high performance was particularly important during a time when Australian cricket faced some significant challenges. Jack's passion for the game was immediately apparent to anyone who enjoyed a day at the cricket with him.

"On behalf of Cricket Australia, I would like to offer my deepest condolences to Jack's wife Sue, his daughters Georgie and Lucy, his extended family and many friends, and all those fortunate to have known him."

Will Rayner, the SACA chair, said: "Jack was one of the true characters of the game. His laugh and zest for life was infectious, and we will miss him dearly."
