Lopeti Timani has turned down the chance to play in Europe in order to join the Melbourne Rebels.
The 22-year-old back-row will make the switch from the Waratahs - with Timani hoping the move will see him follow his brother Sitaleki into the Australia set-up.
Timani, who initially played rugby league for the Canterbury Bulldogs before joining the Waratahs, has agreed a two-contract with the Rebels - and head coach Damien Hill is delighted with the new acquisition.
"At only 22, Lopeti is a player with enormous potential," Hill told the franchise's official site.
"He has played both No 8 and blindside flanker over the past two seasons, and at such a young age will only continue to develop.
"Lopeti has ambitions to represent the Wallabies, and sees a pathway to this goal through the Rebel Rugby program."
