Forwards coach John Plumtree has revealed Ireland are unleashing set-piece giant Devin Toner to dismantle Australia's line-out in Dublin.
Plumtree believes Australia base their attacking platform around first-phase stability, and has backed Ireland to disrupt that foundation at the Aviva Stadium.
Towering 6ft 11in Leinster lock Toner and new captain Paul O'Connell will start together for the first time in Ireland's engine room.
O'Connell has already confirmed he will share line-out calling duties with Toner, who led the aerial set-piece in the 40-9 victory over Samoa.
And Plumtree believes Toner can stabilise Ireland's line-out approach while also causing mayhem on Australia's ball.
He explained: "Dev obviously enjoys winning ball, but a big part of his role is also stealing ball too.
"We've put him into positions where we've given him an opportunity to do that. Also restarts and kick-offs, they are really important parts of the game as well, they are extra set-pieces now.
"The last thing you want to be doing is to concede points straight after you score points, or if you do concede points you want to be able to win that restart and settle straight away.
"So those aspects of his game are obviously really important to us."
Plumtree has warned 27-year-old Toner that he cannot rely on line-out prowess alone, however.
The former Natal Sharks coach has called on the eight-cap second row to continue to improve his ball-carrying in the loose.
