Mitchell Johnson is confident Australia can overcome Shane Watson and Brett Lee's absences - as long as they heed coach Mickey Arthur's warning that it is time to get stuck in against England.
Australia have left it late if they are to manage even a sliver of consolation in the NatWest Series, in which the world number ones trail 3-0 with just Tuesday's last match at Old Trafford to come.
It is in keeping with their hapless tour that batting all-rounder Watson and veteran fast bowler Lee should be on their way home, after both suffered calf strains in Saturday's eight-wicket defeat to England at Chester-le-Street.
Paceman Johnson himself sat that fixture out, with a sore foot, but is fit for selection.
He said of his injured colleagues' misfortune: "It's a big blow, obviously with their experience, but it's something we can work with as well.
"We have a very talented squad here."
After England clinched the series so emphatically at the weekend, Arthur called a team meeting in which he spelled out to his side that they needed to show more "mongrel" out on the pitch, to try to do themselves justice.
"Like Mickey said the other day, we just need to have fire in our bellies and show that belief and go out and do a job," added Johnson.
"We have one more chance to show England and ourselves we're good enough - and I believe we are good enough.
"We're all disappointed to be 3-0 down. We were all excited about this tour ... the guys were keen to get over and perform.
"We just haven't done it on the field.
"I think it's exactly right what Mickey said, because we have the talent.
"We have plenty of guys there, and we need to back up our ability."
Australia will approach the final fixture in isolation, simply another chance to beat England.
"We're going in with confidence; we're not letting the score bother us," said Johnson.
"I think it's a confidence thing.
"It was an honest and firm talk Mickey gave us, and something we all needed.
"Things that were brought up were definitely things we were thinking and certainly warranted.
"He was right about most things, so we need that bit of fire in our belly for this game and prove to ourselves we're good enough to compete with this side.
"We're the number one side and we need to play like that."
Johnson admits he himself has been prey to mental fragility at times, during a career of outstanding and disappointing performances in near equal measure.
Travelling English supporters mocked his efforts during Australia's 2010/11 Ashes defeat, but he believes, after a seven-month rest for mind and body before returning for this one-day international series, he can put those troubles behind him.
"I think back then I let it affect me a lot," he said.
"It's hard not to when that's all you can hear in the cricket ground - your name being sung, and the songs are very catchy.
"I was at that point in my career where I was letting things get to me - it was not necessarily just the crowd, it was everything.
"But I've pushed on past that.
"I've learned to deal with it and I look at it as a reflection of my performances - they are threatened by me a little.
"I've had some pretty good performances against England in the past."
