Jetta was drafted by Sydney with the 14th selection in the 2009 AFL Draft, which had been traded from Collingwood in exchange for Darren Jolly. Jetta is a small, but extremely quick and skilful player who was overlooked in both the 2007 and 2008 drafts, before having a breakthrough year for Swan Districts in 2009. He represented Western Australia in their state game against South Australia in June 2009 and kicked three goals, including the WA's last goal in the final minutes. He is the cousin of Neville Jetta who plays for Melbourne and his brother Graham Jetta plays for Swan Districts. Jetta was impressive against Carlton in the opening round of the 2010 NAB Cup. In 2010, Jetta's debut season, he scored 19 consecutive behinds without a goal. In round 19, against Hawthorn at the Sydney Cricket Ground, he kicked his first goal late in the game to break his streak and received a standing ovation from the crowd. Jetta came third in the 2010 AFL Grand Final sprint, representing Sydney. 2011 was a relatively disappointing year from Jetta as he struggled to have an impact in several games. While he was able to have an influence at times throughout the year when he came on as the Swans' substitute, he often found it difficult to find the ball through 4 quarters of football. Although he suffered a disappointing 2011 season, he had an impressive lift of form in the 2012 season. The most notable improvements in his form are improved foot speed, kicking accuracy and decision making. In 2011, Jetta only managed to kick 9 goals in the entirety of the season, yet by the end of round 16 of the 2012 season he had kicked 36, making him first for goals in the Sydney squad and seventh in the competition itself. Jetta has improved immensely and has credited this to an outstanding pre-season. On 8 June 2013 Jetta re-signed with the Sydney Swans for another two seasons. In October 2015 Jetta was traded to the West Coast Eagles in exchange for Callum Sinclair. In the 2018 Qualifying Final against Collingwood at Optus Stadium, Jetta kicked a crucial goal with 5 minutes to play which gave the West Coast Eagles a five-point lead and ultimately won the match for his team. After kicking the goal Jetta celebrated doing Cristiano Ronaldo's iconic celebration. After the 2018 AFL Grand Final win, Jetta made history with second premiership becoming the 30th player in AFL/VFL history to win a premiership at two clubs
