Winning a Rugby World Cup is the end goal but repaying the NSW Waratahs for their "huge gamble" was the overriding factor in Izaia Perese's decision to remain in Sydney long-term.

One of the most exciting prospects in Australian rugby, Perese has committed to the Waratahs until at least the end of 2024 and looms as a Wallabies X-factor at next year's global showpiece in France.
