A utility player, Lynch began his career as a defender, but later switched to the forward line, leading West Coast's goalkicking in 2006 and 2007 as well as playing in the club's 2006 premiership side.

Lynch quit West Coast at the end of the 2012 season, moving to Collingwood under newly implemented free agency rules.

Originally from Grass Patch,[2] a farming community in the Goldfields-Esperance region of Western Australia, Lynch attended Aquinas College, Perth, where he was captain of the First XVIII team that won the Alcock Cup, and also rowed in the school's First VIII.

[2] He was recruited to the WAFL club West Perth, and in 2001 won selection as the All-Australian centre half-back at the under-18 carnival.

He rarely misses games and with a large injury list and poor club performance through the season he started to play a more midfield role, with his big body around the contest and booming kick being valuable weapons.

A valuable player for the Eagles due to his durability and hard work, although he did not kick as many goals in season 2008 as in previous years.

[9] At the end of the 2012 season, Lynch announced his intention to quit West Coast and become an unrestricted free agent, taking advantage of newly introduced rules allowing players over a certain games threshold to bypass the AFL's draft and trade week.

[16] Lynch married Daneka O'Brien in December 2008 at a ceremony in Margaret River, after dating for seven years.
