Dan McKellar says Australia must avoid getting "sucked into" England's "niggle" when they do battle in the decisive Test at the SCG on Saturday.
The Red Rose levelled the three-match series with a 25-17 victory at Suncorp Stadium last weekend.
Eddie Jones' men came out firing as they stepped up the physicality in Brisbane to bring Australia back down to earth.
Assistant coach McKellar says the Wallabies must keep their discipline if England attempt to get under their skins again with the series on the line.
"It's pretty pointless these days isn’t it?" he said. "You go rushing in and [you're] third man in and you're on the receiving end of a yellow card.
"It all comes down to emotional control and making sure you're not getting sucked into those sort of tactics.
"The officials will be world-class on Saturday and it's their job to look after.
"It's not something we plan or put tactics to in this environment. We have much more important things to worry about that'll go a fair way towards deciding a Test match than a little niggle."
Australia are waiting to learn the extent of a knee injury suffered by Cadeyrn Neville, while they will have to do without Darcy Swain (suspension), Izack Rodda (foot), Jed Holloway (calf) and Ned Hanigan (knee).
McKellar says they must show their strength in depth.
"I think what makes it seamless is the preparation we've done over the past three-four weeks and understanding whoever's playing will be involved heavily in preparation over that period of time," he added.
"You can't be throwing your eggs in one basket thinking they'll get through a series. The game is played at an incredibly high intensity these days, very physical, and sadly we've seen a fair few injuries.
"We've been unlucky in that area and every now and again you get clusters in a position, you just have to make sure your whole squad is prepared and ready to step up if required."
Farrell backs 'composed' Prendergast to shine on first Ireland start
Andy Farrell believes Sam Prendergast is ready to step up ahead of his first Ireland start against Fiji at the Aviva Stadium on Saturday.
Farrell has made seven changes to his team, handing first caps to Leinster's Gus McCarthy and Ulster's Cormac Izuchukwu for the penultimate game of the Autumn Nations Series.
The Ireland head coach has handed Prendergast the number 10 jersey for the first time after he was used off the bench in the closing stages of last week's win over Argentina.
Prendergast has only started eight games for Leinster, but Farrell had no hesitation in handing him a first start after he impressed on the Emerging Ireland tour of South Africa.
"I'm confident from what we've seen. We took him on the Emerging [Ireland] and he played in all of those games," said Farrell.
"The aim of that was to grab hold of that team and make sure that he treated it like it was his own, as though he was in charge, and he did that in spades.
"This week we've seen the benefit of that, but we need to see it transfer, obviously.
"Yes, his character is composed, confident but yet not over-confident. He's assertive in what he wants, and he has a nice way about how he goes about his business.”
Farrell also had a glowing review for Izuchukwu, saying: "Izzy has been in and around the squad for a while. The first Emerging Ireland tour was when we first came across his ability, his athleticism, his point of difference.
"That was a couple of years ago but the improvement in his maturity of his game, because he was young in the 15-a-side game when the first tour was on, but the difference between the first and second tour was like chalk and cheese.
"His ability and potential with that maturity, he deserves a shot to show us all what he's got."
On McCarthy, who captained the Ireland Under-20s to a Six Nations Grand Slam in 2023, Farrell said: "He's been a captain and you can see why because his maturity in how he goes about the game."
He added: "We took him on the training week [to Portugal] as a development player and he showed up unbelievably well. He forced our hand to keep him in the squad first and foremost and he deserves a shot to see what he can do as well."
Ciaran Frawley also returns to the bench after missing out last weekend on the back of a poor outing against New Zealand.
And Cian Healy must wait another week for a record-breaking 134th cap - having drawn level with Brian O'Driscoll against Argentina - after the prop was left out of the 23.
Ireland team to play Fiji
Jamie Osborne; Mack Hansen, Robbie Henshaw, Bundee Aki, Jacob Stockdale; Sam Prendergast, Craig Casey; Andrew Porter, Gus McCarthy, Finlay Bealham; Joe McCarthy, Tadhg Beirne; Cormac Izuchukwu, Josh van der Flier, Caelan Doris (capt).
Replacements: Rob Herring, Tom O'Toole, Thomas Clarkson, Iain Henderson, Cian Prendergast, Conor Murray, Ciaran Frawley, Stuart McCloskey.
'World-class' Scotland will provide Wallabies' sternest test – Skelton
Australia will face their sternest test to date when they continue their autumn tour against a "world-class" Scotland team at Murrayfield on Sunday.
That is the view of forward Will Skelton, who believes the Wallabies' victories in England and Wales have brought a new energy and confidence to their camp.
Having crashed out in the pool stage at last year's World Cup in France before finishing last in the Rugby Championship, Australia have looked a team reborn in recent weeks.
A first victory at Twickenham since 2015 and a 52-20 rout of Wales – their biggest-ever away win in matches between the teams – have made it an excellent tour to date for Joe Schmidt's side.
But La Rochelle lock Skelton feels their toughest assignment is to come this week, saying: "We've won two games, we're very aware of that.
"The Test against Scotland is going to be the hardest one yet. We're excited about this weekend and we're looking forward to ripping into it.
"Physically they're up there with the top five in the world. I think set-piece wise they're really strong.
"You've got a guy like Finn Russell who's a maestro at the back there. I think it's going be a close one and we'll be up for it.
"There's some class players in the Scottish team and, when they're at it they're world-class, so we're going to have to be on top of our game."
Wales must 'show courage and front up' against South Africa, says Gatland
Warren Gatland has urged Wales to "show real courage and front up" in their final Autumn Nations clash against South Africa.
Gatland's side bring the curtain down on a disappointing year when they welcome the reigning world champions to the Principality Stadium on Saturday.
Wales have lost an unprecedented 11 straight Tests, and could go an entire calendar year without tasting success for the first time since 1937.
Gatland has made four changes from last weekend's 52-20 defeat to Australia, with Sam Costelow, Rio Dyer, Christ Tshiunza and Taine Plumtree all coming into the starting XV.
Gareth Anscombe, Aaron Wainwright and Cameron Winnett drop out of the squad, while Adam Beard misses out through injury.
And Gatland wants his players to demonstrate fighting spirit against the Springboks.
"Last week's result hurts, and we are just as disappointed by it as the fans," he told reporters during his pre-match press conference.
"Our focus now is on training and preparing well for our final game of this Autumn Nations Series.
"There were good elements that we can definitely build on going into Saturday, but we have to improve our accuracy.
"We know what a quality side South Africa are and the physicality they bring. This week, we need to show real courage and front up against the world champions."
