The Tasmanian was chosen at pick 14 in the 2005 AFL Draft and made his debut in the number 35 guernsey in Hawthorn's opening match of the season against Fremantle at Aurora Stadium in his home state, Tasmania.

2007 saw Birchall play every game for Hawthorn, and consolidate his role as a running half-back with poise and neat disposal.

Many pundits are expecting the low-key young Hawk to make further progress in 2008, possibly including stints further up the ground.

Birchall's poor luck continued through 2018 and he didn't play any football due to a persistent PCL complaint.

After 720 days, Birchall made his long-awaited return playing for Hawthorn's VFL affiliate, Box Hill.
