Scott Higginbotham says Australia are ready for a Welsh backlash when the sides collide at the Millennium Stadium on Saturday.
Wales are on a six-game losing streak and have lost their last five meetings with the Wallabies, and must win to secure a top-eight seeding for Monday's draw for the 2015 World Cup.
Higginbotham has been impressed with the way Australia responded to their drubbing by France, recording back-to-back wins over England and Italy, and says their familiarity with Wales means there'll be no surprises come Saturday.
"I've played the majority of my Tests against Wales," he said. "They are a tough side to play and they play a similar brand of football to the southern hemisphere game.
"It's very quick and they attack the opposition breakdown out wide and in close."
Despite Wales' poor form, Higginbotham says Australia will be taking nothing for granted ahead of the trip to Cardiff.
"They are a very physical team and that's the type of team I like to play against," he said.
"It was a bit disappointing to see them go down to sides that I thought they'd win against recently.
"Just because a team is off form doesn't mean they can't change that in a week. Our boys did that from the French to the English game and we won't be taking them lightly."
Winger Drew Mitchell, who has scored 30 tries in 62 international appearances, said the Wallabies would be taking the pitch at the Millennium Stadium "absolutely ready to rip into Wales".
"We want to finish this tour on a positive note and do everything we can to win our final Test of the year," he said.
"We're looking to finish with a bang, there's no next week for us."
