Premiership club London Welsh have confirmed the signing of Brumbies back-row forward Lachlan McCaffrey on Tuesday.
McCaffrey, 24, has also gained Super Rugby experience with the Western Force and Waratahs, and featured against the British and Irish Lions for the Force on their Tour of Australia in 2013. He made his Super Rugby debut in 2010 for the Waratahs.
A former U20 international, he helped Australia reach the final of the 2010 IRB Junior World Championship in Argentina, as well as representing Australia at schoolboy level.
Liverpool-born, he played his club rugby for Eastwood in Sydney and was a runner up with them in last year's Shute Shield - Sydney's grade rugby competition.
In 2009 he was the inaugural Shute Shield Rookie of the Year and in 2011 was a member of the Eastwood team which defeated Sydney University 19-16 in the Shute Shield grand final - a side captained by former Exile Mitch Lees.
"Lachlan caught our attention at the Club 10s in Singapore when he was part of the Brumbies squad. I had the opportunity to meet him first hand and have a look at him play, and he really impressed me," said London Welsh head coach Justin Burnell.
"He's EQP and that's very important, but he's also got an excellent and proven pedigree in Super Rugby. He's a typical ball playing Australian forward - he's got a brilliant skill set.
"It's another massive statement by London Welsh in our bid to compete in the Aviva Premiership next season."
