In his five years with the club Podsiadly played 83 games and booted 169 goals. He was leading goal kicker in the 2011 premiership campaign.
"I'll be forever grateful for the opportunity Geelong gave me to play at the elite level and to be a part of the ultimate success as a player is something I'll never forget,"Podsiadly said.
"Over the last five years I've met some great people, been coached by some terrific coaches and played with the most professional, determined and selfless players. They have all made me a better player and person.
"Geelong has developed some fantastic young players who now deserve the opportunity to take the club forward. I would like to wish the next generation all the best and I hope they all have as much fun playing for the Cats as I did.
"Going forward I'm currently exploring further playing opportunities. I will always appreciate how the Geelong members, supporters and staff embraced me from day one. Thank you for making Geelong FC feel like home."
Geelong coach Chris Scott paid tribute to Podsiadly's contribution.
"Podsy has been a great contributor for us both on and off the field," Scott said.
"He took an opportunity when most people would have given up the AFL dream and turned that opening into a great success. He was critical in our 2011 premiership and worked well with the younger players coming through the system.
"James has indicated that he may look to extend his career, and if he chooses to do so we wish him well. Regardless of where the future takes him, Podsy will always be a Geelong person and will hold a special place with his team mates, coaches, staff and supporters.
"I believe with his background he has the capability of continuing to work in the game once he finishes his playing days. He understands the highs and lows the game has to offer and his work in sports science and leadership provides him with a deep reserve of knowledge."
Podsiadly had stints with Essendon (2000-2001) and Collingwood (2002) before becoming a dominant VFL player, mainly with Werribee.
After winning the Liston trophy in 2008, Podsiadly joined Geelong as VFL captain and as a member of the club's sports science unit.
His continued great form saw the Cats select Podsiadly in the rookie draft following the club's 2009 premiership campaign.
Podsiadly debuted in round three 2010 at Subiaco against Fremantle, and kicked 100 goals over his first two AFL seasons.
Podsiadly booted five or more goals on twelve occasions and played in nine finals with the Cats. He helped the Cats to three top four finishes and formed an excellent one-two punch with Cameron Mooney and then Tom Hawkins.
