Andrew Balkwill

Andrew Balkwill (born 24 March 1972) is a former Australian rules footballer who played with Carlton in the Australian Football League (AFL). Originally with Port Adelaide, he and Ben Nelson were traded to Carlton for Brent Heaver at the end of the 1996 season.
Balkwill played his sole game for Carlton in Round 3, 1997 – the game best remembered for Carlton wearing sky blue guernseys as part of a cross-promotion for the new blue-coloured M&Ms. Balkwill never played a senior game in the club's traditional navy blue – which was a unique distinction until the club later introduced clash guernseys.
He is the current Principal of Thomas More College Salisbury.
