Clarke had a strong start to the year in his fifth season at St Kilda, playing in their 2008 NAB Cup winning side.[1][2]
After playing just five of the first 20 rounds in 2008 because of health and personal issues, Clarke finished the year in outstanding fashion, starring at half-back in the semi-final win against Collingwood and being one of the Saints' few good players in the preliminary final loss to Hawthorn.
Clarke played in 12 of 22 matches in the 2009 AFL season home and away rounds in which St Kilda qualified in first position for the finals, winning the club's third minor premiership.[3]
St Kilda qualified for the 2009 AFL Grand Final after qualifying and preliminary finals wins. Clarke played in the grand final in which St Kilda were defeated by 12 points.
Clarke was delisted by St Kilda at the conclusion of the 2012 season and played with St Albans Football Club in the Geelong Football League in 2013 before coaching the Flying Boomerangs national Indigenous youth team in their tour of South Africa.[4]
