Ireland head coach Andy Farrell says handing the reins to Simon Easterby while he temporarily steps aside to focus on the British and Irish Lions will be a "seamless" process.

With Farrell set to lead the Lions for the first time in next summer's tour to Australia, defence coach Easterby will step up for Ireland's Six Nations defence and a summer tour.

Farrell will sign off against Joe Schmidt's Australia on Saturday but is comfortable leaving Ireland in Easterby's "unbelievably diligent" hands.

"We've been working together long enough now to agree on how this team needs to be driven forward with us all involved," said Farrell.

"All our ideas over the years, that will continue. Simon is unbelievably diligent and the right man for the role as far as leading from the front.

"We've had the experience there and we've seen the credentials there and we know it's going to be a seamless one."

When asked about the importance of securing a win against the Wallabies on Saturday before switching focus to the Lions, Farrell added: "Honestly, to me, I've not really give it much thought.

"The only thing that drives me on is planning for the future of this team and that's only been at the forefront of my mind, certainly over the last six months anyway.

"It just so happens that we're here on a big game with the last game, but after that what will be will be. We'll turn that page when we get to it."
