As England and South Africa trade blows like two punch-drunk prize fighters, Australian cricket fans might be forgiven for thinking the result of this topsy-turvy Test series will have little bearing on the Ashes later this year.
To a certain extent that is right. England, who hold a 2-1 lead heading into the final Test at Old Trafford later this week, may gain confidence if they close out the series win.
Report, highlights: Moeen hat-trick seals England win
However, Australia will be a completely different challenge in much tougher conditions for England.
The form of Ben Stokes, though, should be a concern for Australia, the Durham allrounder's player-of-the-match display at The Oval underlining just what a talisman he is for this England team.
After playing a fine innings of controlled aggression to score a match-defining century on day two at The Oval, Stokes' bowling spell on the fourth evening, when he dismissed Quinton De Kock and South Africa captain Faf Du Plessis in successive balls, drew comparisons with Andrew Flintoff.
Usually such parallels can be taken with a pinch of salt coming as they normally do from fans or excited pundits.
Yet the comparison this time came from team-mate Stuart Broad, who said: "That was as quick as I've seen him bowl.
"It was an intimidating spell, a bit like Andrew Flintoff used to bowl – heavy and at the batsman. It was great to get two key batsmen out with genuine pace and exciting to be on the field."
Australia know all about how effective Flintoff was in Ashes battles, his contributions in 2005 and again in 2009 helping England secure memorable home series victories.
The less said about England's 2006-07 tour in between, when Flintoff was captain, the better.
Stokes has relished facing Australia as well, scoring his maiden Test hundred at Perth during his debut series in the 2013-14 Ashes and playing a key role in helping England regain the urn on home soil in 2015.
After a year in which Stokes has established himself as the world's best all-rounder, a return Ashes trip is a prospect that will send his competitive instincts into overdrive.
We know Stokes likes Australia given how well he did in his debut series there four years ago, when as a 22-year-old he shone despite England's car crash of a tour that saw them suffer a humiliating 5-0 Ashes whitewash.
Back then he topped England batting averages, scoring 239 runs at 34.87 and took 15 wickets at 32.80.
This has always promised to be a big year for Stokes ever since he was handed the vice-captaincy of England's Test team back in February. He then became the highest-paid player in Indian Premier League history, going on to be named the tournament's MVP after a fine debut season for Pune.
The fact is he seems to be getting better, rising to the added responsibility of leadership and pressure of expectation.
And that is bad news for Australia, whose last brush with the 26-year-old came when he smashed a match-winning century against them at Edgbaston during the recent Champions Trophy.
Stokes, four years older, wiser and more skilled, will be a huge barrier to Australia's chances of regaining the urn.
He cannot do it on his own of course, other England players will have to come to the party too if they are to stand a chance.
Captain Joe Root, though, knows the value of a fit and firing Stokes.
Speaking after England's win at The Oval, Root said of his deputy: "He's always been a great player but over the last year he's really matured. He's found ways to be more consistent, affect the game.
"He thinks really well and he's got a great cricket brain, which he doesn't always get a lot of credit for.
"He's a person you know you can turn under pressure to wrest a game back in your favour - this week is a fine example of what he's capable of. He works extremely hard and you can see that now, so hopefully he's still on upward curve and has further to go and more to achieve in the game."
Australia, you have been warned.
