His older sister, Coral Farkash, 17, will join him on the trip to Melbourne on Monday alongside Rotorua's Jodie Allely, 16. The trio will all compete in trampoline while Western Heights High School student Damian Hewett, 17, has already left for Australia to compete in gymnastics.
Coral was born in Israel and said she got into the sport at a young age.
"I started gymnastics when I was 5 but started trampolining when I was 12," she said. "I couldn't speak English when I started, and it was the only sport that showed you what to do rather than told you what to do."
Her family also have a history in the sport.
Her mother and coach, Lynette Farkash, represented New Zealand at the Commonwealth Games in gymnastics.
Despite her mother's history in gymnastics, Coral said the switch from gymnastics to trampolining was an easy one. "That's the best decision I have ever made," she said. "I guess I just love the adrenalin."
The Farkash siblings will compete in the individual trampoline, synchronised trampoline and double mini-trampoline.
Meanwhile, Jodie will compete in the double mini-trampoline event only. The double mini-trampoline event sees gymnasts run up to a smaller trampoline where they bounce twice before dismounting on to a mat.
Jodie said it was great to compete in Australia but her biggest goal in the sport was to become an international judge.
"I want to become an international judge and judge at sanctioned competitions."
She is currently earning her qualifications as a judge while competing in trampoline. The group of four athletes had to qualify to attend the Australian Gymnastics Championships during sanctioned events in New Zealand.
