Wallabies flank Scott Fardy admitted the Australian loose forwards must improve to beat a physical English back-row at the breakdown.
Australia lost 39-28 to the English in Brisbane on Saturday and a big component of the victory was English grit in the collision area and rucks.
"In that first half they took a couple of key turnovers when we were down in attack," said Fardy.
"Obviously Haskell did a great job and had a good game.
"We've just got to make sure it's a whole 15-man thing. That we're strong in our cleanouts and to the ball quickly because England got over the ball very well.
"I thought it was a pretty run of the mill performance from the (Wallabies) back row, but I think we could be better."
Fardy lamented his side's discipline on the day as they conceded 18 points through penalties.
"That's what got England the game, six penalties they kicked," he said.
"When you score four tries to two before the 79th minute and you're still behind, it's a disappointing thing."
Australia play England in Melbourne this weekend at AAMI Park.
