Leinster have announced the signing of Australian second row Kane Douglas from the Waratahs.
The 24-year-old, who made his Wallabies debut against Argentina in 2012 and has gone on to win 12 caps, will join the Irish province once his Australian Rugby Union contract expires later in the year.
"It's a big decision but one which I am very excited about,” said Douglas.
"I've had plenty of time to weigh lots of things up and the time is right for me and my partner to experience something new and something totally different.
“We are heading for a new challenge in life and that's what excites us.”
He added: "Leinster is a massive club in Europe with a proud tradition and I'm really looking forward to doing my bit to add to the team once my commitments are done here in Australia."
Leinster head coach Matt O’Connor welcomed the addition of his fellow Australian and confirmed that former skipper Leo Cullen will become the province’s forwards coach.
“We are delighted to be able to formally announce Kane's signing,” said O’Connor. “For a young guy he already has a wealth of rugby knowledge and experience under his belt and we also feel that he has the right character to succeed at Leinster.
"We can also formally confirm Leo Cullen's role as our forwards coach effective July 1. He will bring a huge amount to Leinster Rugby as a coach and will continue the excellent work that Jono Gibbes has done over the last six seasons.
“As a three-time winning Heineken Cup captain he already commands the respect of the players and that won't change.”
O’Connor also announced that Richie Murphy has signed a new deal with Leinster as assistant coach, with responsibility for skills and kicking, while former Australia hooker Marco Caputo will be joining the province as scrum coach.
