Socceroos skipper Mile Jedinak today vowed to throw everything at Peru on Tuesday and called on fans to do the same.
If Australia can get a win against the South Americans and France beat Denmark, it will let the Socceroos progress to the round of 16 for the first time since 2006.
But although Peru are definitely out the competition after losing to both France and Denmark, Jedinak is not taking anything for granted.
"We've got this massive game on Tuesday," he said after training today. "We know we're going to have to lay everything out on that pitch together as one.
"Not only with us but with everyone else in that stadium who's supporting us to get this job done. I have no doubt Peru are going to give it a go.
"They haven't been here on this stage for a very long time so to think they're just going to turn up and not care about the game or be disillusioned... it's wrong to think that.
"We're expecting a very, very tough game."
The Socceroos have had their final training session in swelttering 30C+ conditions in Kazan before flying out to Sochi later today.
Andrew Nabbout was the only one missing from the squad at training, but he watched the workout from the stand with his dislocated shoulder strapped up in a sling and looking very unlikely to appear against Peru.
With a likely round of 16 play-off against Croatia in Nizhny Novogorad at stake, the Socceroos are pumped for Tuesday's showdown with Peru and possible progression past the group stage.
"It would be a huge achievement for us and this national team and this group of players," said Jedinak today.
"Everyone knows the journey of the last four years and what it's taken for us to get to this point and how we've grown and matured as a group.
"We've brought some players through and grown as a group. We've been through a few ups and downs, and I think everyone has come out of it better for it.
"You can see that in our performances of late."
The future does not lie entirely in the Socceroos' hands though and they are reliant on the result of the France-Denmark game to go in their favour too.
"We need a little bit of luck as well," the veteran Socceroos skipper admitted. "we want to get as far as we possibly can. That's been the target since day one.
"We've got to this stage and given ourselves every possible chance. We'll keep holding on to that until it's taken away from us."
