Regardless of what transpires in Wednesday's ODI series decider against India, Australia won't lack belief at the World Cup.
Australia's record was a pitiful four wins from their past 26 completed one-dayers last week, having slipped 2-0 down in the current five-match series.
There was no sign of panic and the tourists are now on the cusp of making history.
Australia have never battled back from 0-2 down to win a five-match bilateral ODI series.
They are also on the cusp of their first ODI series win overseas since 2016 and first in India since 2009.
The turnaround has came through an astonishing record chase of 359, completed by Ashton Turner, in the fourth ODI.
There was also a polished bowling performance in the third ODI, in which not even a Virat Kohli century was enough to get India over the line.
"It's felt like probably the last six-to-twelve months that we've been building a really strong group and the results are starting to show," vice-captain Alex Carey said.
"To pull off a chase like that (in the fourth ODI), it's obviously a really good feeling but it's not a huge surprise.
"We knew we were building towards something special.
"It gives us a lot of confidence. We're really excited to level the series and play for a series win, it's what we came over here to do."
Marcus Stoinis is desperate to prove his fitness in the nets but the visitors are likely to take a conservative approach with his broken thumb.
Such a decision would likely result in an unchanged XI, although if the pitch is spin friendly then Nathan Lyon could be recalled at the expense of Jhye Richardson or Jason Behrendorff.
Several players have made the point that three pressure-laden games, in which defeat would have resulted in a series loss, is ideal preparation for the World Cup.
The seeds of Australia's resurgence were sown last year in England, when the World Cup favourites smashed Australia during Justin Langer's first series as coach.
"That was an interesting tour," Carey recalled of his maiden ODI tour.
"Turned out five-nil but for the group over there, we knew how close we were in most of those games.
"We've done lots of good work since. The last 12 months has been a really big learning phase."
Carey and teammates vowed to learn from the best during that tour of England.
The same mantra applied during the current series plus the corresponding ODI series against India at home in January.
But there is now a sense of confidence that Australia can get the job done against Kohli and other superstars.
"We've competed really strongly against them in the past and now we're starting to win," Carey said.
