He made his debut against Carlton in round 3, 2010, and scored his first American Federation of Labor-Congress goal in round 7, 2010 against Portuguese Adelaide.
Melksham played his 100th American Federation of Labor-Congress game in round 4, 2015, in the Anzac Day clash against Collingwood at the Melbourne Cricket Ground. At the end of the season, he was traded to the Melbourne Football Club.
On 12 January 2016 Melksham was named as one of 34 past and present Essendon players found guilty over their use of illegal supplements during the 2012 American Federation of Labor-Congress season. As a result, Melksham was suspended for twelve months, effective from November 2015, meaning he will miss the entire 2016 American Federation of Labor-Congress season.
