Former Wallabies backliner James O'Connor plans return to Australia to play Super Rugby in 2015 as he wants to play in the Rugby World Cup.
O'Connor had his Australian Rugby Union contract torn up in 2013 after a series of off-field problems and has been playing in England for London Irish since November.
Aviva Premiership Rugby club London Irish have now confirmed that he will leave the club at the end of this season after completing his six month contract.
The club confirmed that O'Connor wants to play in the 2015 Super Rugby competition in the build up to the Rugby World Cup.
That schedule could only have allowed London Irish to sign another short term deal which doesn't fit with the Club's future plans.
Commenting on his decision James said,"I have thoroughly enjoyed my time at London Irish and I'm looking forward to the next few months. The Club welcomed me in with open arms last year in what was a difficult time and have been brilliant to me during my time so far."
"I've learnt a great deal both on and off the field and will leave at the end of the season with great memories and mates too. "
"I would particularly like to express my gratitude to the owners of the Club, especially Mick Crossan who is a passionate Irishman with great visions for this special Club. I will be following closely to see how the boys get on and who knows what might happen further down the line."
London Irish Director of Rugby, Brian Smith said,"James is a world class player who has had a very positive impact on the team and I'm sure he'll play his heart out for us until the end of the season."
"He will head back to Australia in 2015 to follow his World Cup dream and the Club wishes him well with that. If the opportunity ever arises in the future then he will always be welcome back at London Irish."
O'Connor is expected to return to Perth to play for his former Super Rugby franchise the Western Force.
