With England's one-day team in such disarray, the biggest stumbling blocks between Australia and a seven-nil clean sweep could be laid down by one of its own.
The series won, Australia already has one eye on its opening Champions Trophy game against the West Indies on Saturday week in Johannesburg.
It rested Brett Lee on Tuesday night, and over the course of the remaining two games will try and give paceman Ben Hilfenhaus and batsman Adam Voges a chance to shake off the cobwebs.
The balance between maintaining the winning streak and giving itself every chance of success in South Africa will only be difficult if the reinforcements are not up to it.
Mitchell Johnson is due for a break. He hasn't missed a game since the opening match of the Ashes tour way back in late June.
The Australians learned the hard way during the Ashes that Johnson is a bowler who performs best with plenty of overs under his belt.
Heading to South Africa with 10 less overs will not undo the gains he has made since his horror show at Lord's in July.
Hilfenhaus, as he showed during the Test series, has a game perfectly suited to English wickets.
Should he also be able to swing the white ball like he did the red, he will provide England's underperforming batsmen with yet another problem to overcome.
Australia's batsmen have done all that has been required of them but one senses only the surface has been scratched in term of what they can produce.
Shane Watson and Tim Paine are knocking on the door of big scores. They have given Australia solid starts but a more ruthless approach will be required against the better sides such as India and Pakistan.
Paine's glovework, however, has been clean, particularly standing up to the stumps to Nathan Hauritz and Nathan Bracken.
Opportunities have been fleeting for Michael Hussey, who has arguably the toughest job in Australia's one-day side - scoring freely at the death.
Batting at No.6 can be a hit or miss affair in one-day cricket. Invariably, there is no time to get a sighter.
In this series, Hussey has arrived at the crease before the 43rd over on just one occasion and produced just 42 runs.
Cameron White's stocks have soared in the past fortnight and he may no longer be the batsman who gets tipped out for team balance.
A promotion to No.4 will give Hussey, who has just 42 runs this series, the chance to notch up a big score so that when he needs to produce the goods in South Africa he can stride to the crease free of doubt.
England's batsmen, still searching for their first century, deserve to carry the can for their side's abject failure, the last game included.
That sounds harsh given they gave their bowlers 300 runs to defend. But had one of their top six converted their start into a ton Australia could have been chasing 330 instead.
That said, the Poms lack the firepower of Australia in their attack. Tim Bresnan, Luke Wright and Dimitri Mascarenhas don't quite strike fear like Andrew Flintoff.
If only Flintoff was making headlines for his deeds on the field rather than off.
