The Wallabies did little to dispel the theory in the north that while they're brilliant playing the pace of a Southern Hemisphere clash, Australia are vulnerable when attacked at the set-piece and physically belted at the tackle.
Ireland did both, with huge games from their front row and their dynamic back row denying Australia any continuity.
"When you have no momentum and the other team has all of it, nine times out of 10 you are going to be on the back foot. Which makes it very hard to win a game," first five-eighths Quade Cooper said.
Wallaby players deny there is a soft underbelly to their game, but a lack of physicality has been a constant when beaten over the past few years. Without muscle up front, dogged persistence in seeking to crack defences with pace out wide doesn't get far.
Captain James Horwill said yesterday that improving their physical presence was a priority. "The contact zone is an area we came off second best ... It is a critical part of the game.
"It is an area in this tournament that the teams that dominate that breakdown area are usually the teams that get the result. That will be a focus for us for sure."
Big improvement must be made in the scrum as well.
