He is best known for finding a fake Hidden Immunity Idol crafted by Ozzy Lusth on Exile Island and genuinely believed it as the real one. He did find a real idol days later, but found himself blindsided, sending him home with the idol in his pocket.
Jason Siska is currently living on St. John USVI at a local dive shop. He previously worked as a nude model for the Illinois State University Art Department, a carpenter/construction worker and after-school supervisor for Glenn Elementary School. He studied history and Spanish for four years at Illinois State University.
Born and raised in St. John, U.S. Virgin Islands, Siska moved to the "gold coast" of Chicago for five years before moving to the Barrington area for eight years. He then moved to Normal, Illinois for college.
Siska's hobbies include frisbee, rock-climbing, soccer and sailing. He describes himself as spontaneous, liberal and inquisitive. He is most proud of traveling alone for a summer in Central America and volunteering his services in Costa Rica and then backpacking through Columbia and the Lost City. He believes his abilities to rock-climb, fish, hunt, camp, cook, fire-tend, swim, boat and being a great masseuse will help him go far on SURVIVOR. He is also a certified PADI scuba diver.
Siska is currently single and lives in St. John, U.S. Virgin Islands, with his Himalayan cats, Baby and Little Girl.
Jason Siska, being a fan of Survivor was placed on the Airai tribe. He was thrilled that he would be competing against the most popular castaways from seasons past. Jason was dismayed when Kathy Sleckman found the idol that gives its holder immunity at their tribe's first tribal council, viewing her as the first to go. Airai won the first immunity challenge, keeping the group safe. During the time, Jason became a part of the majority alliance which excluded the older members. Jason like the other fans applauded the favorites when they voted out Johnny Fairplay. Malakal won a joint reward-immunity challenge, sending the fans to tribal council. Jason decided to vote out Chet Welch based on how horribly he performed at the challenge. Much to his shock, Mary Sartain was voted out instead. The Favorites proved to be the stronger tribe but the Fans won the next immunity challenge. Unfortunately, the favorites resumed their dominance and won the next challenges. Jason was set on voting off Chet, but Tracy Hughes-Wolf told Joel Anderson that Mikey Bortone wanted him out. Jason pleaded with the tribe to keep it strong, noting that they lost four out of the six challenges. Jason plea was futile as it only earned Alexis Jones' vote and Mikey B. was voted out.
A Tribe Switch occured on Day 13. Jonathan Penner selected Jason to stay on Airai. He chose Parvati Shallow, whose name he mispronounced. The new Airai was dominant in challenges and won four consecutively. Despite not going to tribal council, the tribe lost Jonathan due to a knee infection and Kathy because she quit due to the harshness of the conditions. Jason was sent to exile back-to-back and he found what he thought was a hidden immunity idol during that time. He also befriended fellow outsider, Eliza Orlins. Airai won the next immunity challenge.
On Day 22, the tribes merged and moved to the Malakal camp. Jason was immediate target for his athleticism and being on the outs. However, he outlasted Ozzy Lusth for immunity and gave his supposed Idol to Eliza. Eliza came to him and called it a fake. Jason hoped it was real and still voted for Ozzy. Eliza played it just to confirm that Ozzy had the real one, and she was voted out. At the immunity challenge, it came down to him and Parvati. When Jeff offered food for the whole tribe, Jason offer to step down on the condition that no one write his name down at tribal council. Everyone agreed and Jason stepped down, giving Parvati immunity. The Favorites alliance, however, went back on their word and decided to vote out Jason. Cirie Fields, however, felt this was the best time to blindside Ozzy. Cirie's plan came to fruition and Jason was spared.
At the Survivor Auction, Natalie Bolton brought a note allowing her to exile someone and take all their money. Jason told her he didn't want to go back to Exile but Natalie sent him anyway, much to his despair. Natalie said he was overreacting and said he could find a immunity idol. Jeff noted this time, maybe a real one. Jason found the Idol. Unable to win immunity, Jason thought that James Clement was the next to go for his strength and determination. Jason did not play the idol, which would cause his demise. Jason was blindsided in a 4-3-1 vote. As a juror, Jason gave his vote to Parvati, which was pivotal in crowning her Sole Survivor.
