Sydney Swans high flyer Isaac Heeney is aiming to become winner of the AFL Mark of the Year award for a second consecutive year after being nominated for the honour.

Heeney is one of three finalists for the award with West Coast livewire Liam Ryan also holding the other two nominations.

It was just 60 seconds into the Swans season when Heeney leapt onto the shoulders of Western Bulldogs defender Bailey Williams to pull down a screamer.

The number 5 soared high at Marvel Stadium to have the crowd in awe as he plucked one of the best marks taken this season.

Heeney took out the AFL Mark of the Year in season 2018 for his high flying specy over Melbourne forward Jesse Hogan late in the season.

Voting opened on Thursday and will remain open until Friday 13 September.

The winner will be announced at the Brownlow Medal on September 23. The public vote counts as one vote while the All Australian committee counts as 10, so fans have their chance to have a say in the final winner.
