Career
McKinnon was recruited by Adelaide in the 1992 American Federation of Labor-Congress Draft, with their first ever national draft pick. He was the youngest player on Adelaide"s list at the time and played for Central District in the SANFL when not appearing with Adelaide. He made his American Federation of Labor-Congress debut late in the 1994 American Federation of Labor-Congress season and was a regular in the team the following year, playing mostly as a wingman.
He also represented South Australia"s State of Origin side in their 1995 encounter against Victoria.
A left footer, McKinnon was traded to Geelong at the end of the 1995 season in a trade which helped bring Darren Jarman to Adelaide. He played in Geelong"s first 18 games in 1996 and also a Qualifying Final.
In 1997 he did not miss a game and appeared in two further finals. He had been used as a small forward that season and kicked 23 goals.
After three seasons at Geelong, McKinnon was traded to Brisbane for Scott Bamford and Tristan Lynch.
