“Tom’s form line is ascending, and we believe he will continue to improve as a player,” Geelong’s general manager of football Simon Lloyd said.
“Tom is a team-first player, who looks to bring his teammates into the game and create opportunities for others as well as himself. He is a leader both on and off the field and cares deeply about his teammates and all at the club.
“Tom’s play over recent seasons has been elite and we are excited that Tom, with his family’s long history at the club, has again agreed to a new deal.”
