His 2006 form with North Adelaide Roosters was not the best but impressive results at the South Australian state screening saw him drafted by the Crows with the 64th pick of the 2006 AFL Draft. The Crows also drafted Gill as a mature-age recruit to act as insurance for the injured Trent Hentschel.
Despite not having the best of starts after being plagued by hamstring injuries at the start of the season, Gill eventually worked his way back into form to be picked for his first game in a forward pocket for the Round 17 clash against the Essendon Football Club in 2007.
In 2008 Gill was in and out of the side, becoming a fixture late in the season due to injuries to several key forwards.
Gill but struggled with injuries in 2009, and was unable to break into a suddenly potent Adelaide forward line. At the end of the season, he was one of five players delisted by Adelaide.[2]
