Gilchrist was renowned for walking when he considered himself to be out, sometimes contrary to the decision of the umpire. He made his first-class debut in 1992, his first One-Day International appearance in 1996 in India and his Test debut in 1999. During his career, he played for Australia in 96 Test matches and over 270 One-day internationals. He was Australia's regular vice-captain in both forms of the game, captaining the team when regular captains Steve Waugh and Ricky Ponting were unavailable. He retired from international cricket in March 2008, though he continued to play domestic tournaments until 2013.
