- An overactive child, Josh Jefferis got involved in the sport of gymnastics and trampolining after his parents were advised to sign him up at the age of three to use his excess energy. It proved a master stroke with Jefferis now having claimed three National Championships, four Commonwealth Games gold medals and will now take on the world's best in London.
- At the age of 10 he commenced at the Queensland Academy of Sport where he trained for 30 hours a week for 10 years before joining the AIS in 2005.
- After winning his first senior national title in 2005, Jefferis debuted at the 2006 Commonwealth Games in style as he won the all around and rings event, claimed silver in the teams and bronze on the parallel bars. He went on to win another two gold medals in Delhi at the 2010 Commonwealth Games as a part of the first Australian team to claim Commonwealth victory, while also winning the parallel bars and securing bronze in the all around.
- After being called up to compete at the London test event after Sam Offord was injured, Jefferis performed strongly as he qualified Australia the one position in the men's artistic competition in London. Following a number of lead up competitions, the race to for the spot came down to Jefferis and his good mate, and reserve on the team, Thomas Pichler at the 2012 Australian Championships. Jefferis showed his class to win the title and despite having doubts over whether he would compete at the test event has now booked his ticket to London.
- The gruelling toll that the sport takes on the body has seen Jefferis battle a host of injuries throughout his career that saw him need surgery on his shoulder, elbow, wrist and forearm in between his Commonwealth Games campaigns. He has graduated from his applied science degree and is now completing his masters in physiotherapy.
