London Irish have confirmed the signing of Australia international James O'Connor until the end of the season.
The Aviva Premiership side were widely expected to announce the capture of the Wallabies back, who will be looking to use the move as a means of forcing his way back into the national squad before the 2015 World Cup.
O'Connor is expected to make his debut for the Exiles in Sunday's clash against Northampton.
"Having decided that I needed a change from both a personal and playing point of view, I spoke to clubs in Japan and France and concluded that the best way forward for my development was to move to England," said the 23-year-old.
"Given that I've left my support network back in Australia, London Irish offered me an environment that I felt comfortable with."
O'Connor has had his share of run-ins with authority during his career:
August 2011 - Suspended for one match and given a suspended fine after missing the Wallabies' official Rugby World Cup 2011 announcement.
June 2013 - Photographed in a fast-food outlet in Melbourne at 4am with team-mate Kurtley Beale just three days before the crucial second British and Irish Lions Test match against Australia.
July 2013 - Misses a Wallabies' team meeting after a defeat by the Lions at ANZ Stadium and also misses the team bus to training.
July 2013 - Released by Super Rugby side Melbourne Rebels, with the franchise stating they are "entering the next phase of development".
August 2013 - Barred from taking an international flight and then removed from Perth Airport by Australian Federal Police following the Wallabies' win against Argentina after he is alleged to be "intoxicated".
October 2013 - Has his contract with the Australian Rugby Union terminated for disciplinary reasons.
The former Western Force and Melbourne Rebels player has had a chequered career since making his Australia debut as an 18-year-old in 2008.
He has added a further 43 caps to his tally, with his footballing ability seeing him fielded at fly-half, centre, wing and full-back.
He played at number 10 during Australia's 2-1 Test series defeat against the British and Irish Lions in the summer, scoring a try in the Wallabies' third Test defeat.
However, his off-field behaviour saw him ditched by the Australian Rugby Union last month after an incident at Perth airport, where O'Connor was reportedly escorted from the premises after arguing with airline staff.
Australia coach Ewen McKenzie insisted the decision did not close the door on O'Connor's Test career, but admitted the player has to "modify behaviour".
Four days prior to the second Test of the Lions series, O'Connor and team-mate Kurtley Beale were photographed at a fast-food restaurant in Melbourne at 4am in the morning, while the utility back had previously missed buses to training and team meetings.
In 2011 he received a one-game ban for missing Australia's World Cup squad announcement, but his on-field ability has never been called into question and his availability prompted interest from several top European clubs.
His decision to move to the Madejski Stadium could also invigorate the Exiles, who have lost four of their opening six Premiership fixtures.
O'Connor views the move to Irish as critical to his "personal development" that would have been hampered had he stayed in Australia.
"Away from the field I need to find balance in certain ways. I've been in bit of a bubble in the last six years," O'Connor said.
"I've enjoyed it and wouldn't take anything back, it's been an amazing ride. Every opportunity to pull on that gold jersey has been awesome.
"But I've been protected quite a lot. I've made mistakes and haven't dealt with them in the way I'd like to.
"This opportunity gives me the opportunity to become my own man and work on that. It's a good environment to do that."
O'Connor played all three of Australia's Tests against the British and Irish Lions at fly-half, but he sees his long-term future at full-back.
"I want to develop into a world-class 15," O'Connor said.
"I've played all over the park which has been a good thing for me, that utility ability has got me into a lot of teams, but at the same time I haven't been able to nail down one position.
"It's always been my goal to be a world-class player in one position."
Irish director of rugby Brian Smith described O'Connor as the "most significant signing in the club's history".
"His signing is the injection of class we need," Smith said.
