Berrick Barnes reveals desire to play in Japan at end of Super Rugby season Waratah Berrick Barnes has plans to play in Japan but still wants to turn out for the Wallabies at the 2015 World Cup. BERRICK Barnes has confirmed he is seeking a release to play in Japan after the Super Rugby season concludes - but the Wallaby star wants to return for the 2015 World Cup. Barnes is close to finalising negotiations for an early release from his contract with the Australian Rugby Union, which expires at the end of the year, to join the Panasonic Wild Knights in August. It is believed the ARU have all-but agreed to let the 50-Test NSW playmaker depart in a career move that will see Barnes potentially play for the Wallabies against the British and Irish Lions in June-July, but not the 2013 Rugby Championship. Barnes said yesterday he'd not yet signed a contract with the Wild Knights but conceded the move held great appeal. "If Japan works out, I am excited about it," Barnes said. I think it is a great opportunity for me and my family. If that works out I am looking forward to it. But in saying that I have six months here, which I hope will be a really great six months. That's what I am trying to make it. But if I was to go I don't think it would be the last time I would play in Australia. Asked if he still wanted to participate in the 2015 World Cup, Barnes said: "Definitely. I would be lying if I said that wasn't one of my goals. But there is a lot of things to go before that even comes to being an opportunity, playing-wise. Barnes, 26, said the uncertainty of the future played a role in his urge to explore offshore options. It's just where I am in my career. I have to make a decision on what's best for me and my family, and obviously my body too. I have to think about those sorts of things," he said. Two years I was thinking about giving it away (with concussion), so you don't know where you are going to end up. Barnes' decision to leave is likely to see him out of the running for the Waratahs' 2013 captaincy, which will be announced today at the Tahs' season launch. Dave Dennis is believed to be the front-runner for the role, ahead of last year's skipper Benn Robinson, Adam Ashley-Cooper, Michael Hooper and left-field candidate Wycliff Palu.
