Michael Hooper wants to wrestle Australia's number three world ranking back from Ireland.
"To get the win over South Africa is great for them and puts the pressure on us to get a win," said the Wallaby captain.
"They're at number three in the world now, a spot we've held for most of the year, and we have to try to get back.
"To do that we've got to get through these guys first," he warned.
The return of Michael Cheika to Dublin should give Australia an extra mental edge to not make the mistake of following in the footsteps of the defeat to France in Paris where Hooper's coach also worked, for Stade Francais.
"A lot of us have seen a lot of Michael and how he goes about his business and, after the game against, French it was a tough one for him because we didn't get the result.
"We didn't shut out the game for him and for the people back home. It was disappointing but we are pumped to get the result here this week for him and for the people back home."
Hooper recognises a strain of confidence coursing though the Ireland side which is in contrast to Australia's inconsistency, brilliant in patches, unconvincing for other stretches.
"You have to be confident in world rugby and they are confident at the moment, so they're going to prove tough to beat," he said.
"We're building. We're up and down. We're inconsistent, at the moment, and we're chasing consistency, so we want to pick up from where we where against Wales and keep going on that incline".
There has been a tendency to take one step forward and two back.
They showed this against France in Paris where Hooper felt the outcome was kind to the Aussies after they fell behind in the opening quarter of a torrid encounter.
"We weren't unlucky," he said.
"It was the way we played and it was reflected on the scoreboard. In fact, it was a scoreboard that maybe even flattered us a bit.
"We're trying to nut out what's going wrong, especially what we're going through for the next two weeks and then into next year."
Australia have so many weapons, so much ingenuity that it would take a foolish man to count them out.
