The free agency period officially begins on Friday with over 20 players from across the competition eligible to become a free agent.

Essendon has just Dustin Fletcher eligible for free agency with the club continuing to work with the veteran defender to decide whether he plays on next season.

An unrestricted free agent may move to the club of his choice. If an unrestricted free agent does not wish to remain with his original club he must enter the draft or seek a trade.

An offer to a restricted free agent may be matched by his club, which has the right of first refusal of his services.

We take a look at the players from across the competition yet to re-sign with their club that are eligible for free agency.
