Alex Gregory achieved the distinction of becoming one of the youngest players in Australia to secure a rookie contract at the remarkably tender age of 17. As an all-rounder, he continues to hold a rookie contract with the Redbacks, and his versatility with both bat and ball adds a valuable dimension to his cricketing prowess. In 2015, Gregory received the honor of being appointed vice-captain of the inaugural Cricket Australia XI, which participated in the 2015 Matador Cup. Although he did not feature in any matches for South Australia during the 2015-16 season, he made a significant impact while representing the Sturt Cricket Club. Notably, he accumulated a total of 664 runs, with a notable high score of 137, in addition to taking 18 wickets during the season, showcasing his all-round abilities.
