Outstanding inside back Samu Kerevi wants to quit the Wallabies for Fiji at the next World Cup.
A report in the Fiji Sun said Kerevi, who is about to play in Japan, made the "bombshell revelation" at a luncheon in his homeland.
Kerevi's three-year contract with the Suntory Sungoliath makes him ineligible for the Wallabies, who will only select overseas-based players who have reached a 60-test threshold.
That is being reviewed by Rugby Australia over summer, and a rule change could keep the 33-test Kerevi in Australian colours.
The loss of Kerevi would be a massive blow for the Aussies.
