Rooke was recruited from
Casterton in 2001, and he made his debut in the second round of 2002. In 2003, he was awarded Geelong's most determined and dedicated player award. Rooke was a regular senior player until a shin injury forced him to miss the second half of
2004, including the finals series, but he recovered to play all but one game in
2005. His lack of pace against small forwards was exposed in Round 20, 2005, when 's
Russell Robertson kicked six goals against him. This prompted coach
Mark Thompson to move him into the midfield the following week. This move was successful, with Rooke nullifying
Hall of Fame midfielder
Chris Judd. In Geelong's close loss to the
Sydney Swans in the 2005 semi final, Rooke laid a remarkable fifteen tackles. Rooke missed out on most of Geelong's
2007 season after suffering a potential season-ending 7 cm hamstring tear in Round 13. On 12 July, Geelong spent $20,000 on Rooke to receive treatment by soft-tissue expert Dr Hans-Wilhelm Muller-Wohlfarth in Germany. ==Coaching career==
