Luke Rooney has been released from his commitments to Worcester Warriors - and turned his back on England in the process.
Rooney, the former Australia rugby league international who has spent two seasons at French club Toulon, has agreed a two-year deal with the Melbourne Rebels.
The 27-year-old winger, a British passport holder, has been lured back to Australia by the new Super 15 franchise in a move that signals the end of his ambition to play for England.
He had hoped that joining Worcester would improve his chances of England selection, but the club's relegation from the Guinness Premiership has prompted him to accept the Rebels' offer.
The Warriors agreed to the move but retain an option on him should he return to the northern hemisphere.
"I'll be concentrating on playing my very best rugby for the Rebels. After that who knows?" said Rooney.
"Of course it would be great to play for the Wallabies, but I've got so much work to do before I can think of getting there."
Worcester, meanwhile, have signed utility back Tom Arscott on a two-year contract from Bristol, completing the club's recruitment for their new Championship campaign.
