Jack Nowell insists England will be "brutal" in their pursuit of completing an historic series triumph in the southern hemisphere against one of the sport's superpowers.
Victory at AAMI Stadium on Saturday will give Eddie Jones' Grand Slam champions an unassailable 2-0 lead after Australia were dispatched in the Brisbane opener last weekend.
Nowell has been restored to the starting XV at the expense of Marland Yarde and the Exeter wing has outlined the approach England will adopt to topple the World Cup finalists.
"This week we've spoken a lot about being desperate again, doing anything to get the win and being brutal when we're out there," Nowell said.
"We want to be physical like we were last week but also tighten up our defence a bit as well.
"Australia are a dangerous side with ball in hand. We knew that before we came into the game. We've worked on the defensive side this week."
Nowell was dropped to the bench for the first Test due to being "de-trained" during the course of helping Exeter reach the Aviva Premiership final, the first time he has not started when available since Eddie Jones took over.
Yarde was given his place in Brisbane and the Harlequin made minimal impact, making little headway in attack and on one occasion he was driven backwards in defence.
Jones insists the industrious Chief is now ready to face Australia from the start, valuing his work-rate over Yarde's greater physical presence.
"Jack is just a bit sharper now. Like all the players, at this time of the year they've got small ailments - some of them affect the players and some of them don't," Jones said.
"He had a small ailment that affected him and now it is very minor and he's moving much better. He's a work-rate player and that's going to be really important on Saturday.
"He doesn't need to be dropped to be motivated to train well and if he did, he wouldn't be in the squad.
"Yarde played two in a row. Some guys can keep their form for long periods of time, other players come in and out. He's a young guy and I'm really pleased with the way he has gone.
"It's a change just for this game. There is no secret how Australia are going to play. To have a high work-rate wing like Jack Nowell is an advantage."
Jones has restored a second member of his Grand Slam team to the starting XV after recalling George Ford.
He starts at fly-half and Owen Farrell moves to inside centre in a positional switch, taking the place of Luther Burrell who is omitted from the 23 altogether.
Burrell was replaced 28 minutes into the clash at Suncorp Stadium after his defensive frailties were exploited by Australia and the tourists' fightback coincided with Ford's arrival and Farrell's switch to inside centre.
It was the first time Ford had been dropped under Jones but after just one match on the bench, the head coach has reverted to employing the twin playmaking option that served England well in the RBS 6 Nations.
"Their understanding of the game for 23 and 24-year-olds is absolutely outstanding, they have got a great command of the game," Jones said.
"They have got a great command of game sense and game understanding and that is important in big Test matches.
"Now we get kicking options at 10 and 12, they are good communicators and they give the team good energy."
