Isaac Heeney has been announced as the winner of the 2018 AFL Mark of the Year award.

Heeney was presented with his prize, $10,000 thanks to Woolworths, during Monday night's Brownlow Medal Count Ceremony at Crown Palladium, Melbourne.

Heeney took the Mark of the Year in Round 21 against Melbourne at the MCG when he flew high late in the game to take a speccy over Jesse Hogan.

Heeney won ahead of fellow finalists Charlie Cameron (Brisbane Lions - Round 9) and Michael Walters (Fremantle - Round 20). 

After each round of the season, footy fans voted for their favourite weekly Mark of the Year from a selection of three marks as nominated by the AFL. 

In addition to the 23 weekly winners, the AFL chose an additional five marks from the season to be considered by the AFL All Australian committee in determining the season’s top three.

The AFL All Australian committee voted, and their results determined the top three marks of the season out of the 28 in contention. These marks were selected based on a 5/4/3/2/1 vote given by each member of the selection committee.

The ten-person AFL All Australian committee consists of: Gillon McLachlan (chairman), Steve Hocking, Kevin Bartlett, Luke Darcy, Danny Frawley, Glen Jakovich, Chris Johnson, Cameron Ling, Matthew Richardson and Warren Tredrea.

The most popular fan choice will then become the eleventh vote when the AFL All Australian committee meets again to cast a single vote for the overall 2018 AFL Mark of the Year winner.
