One of the challenges in the immediate aftermath of Bangladesh’s stunning nine-wicket win in the first Test against Australia at Darwin was to arrange emotions in a socially acceptable sequence.The general consensus was something like this: Bangladesh brilliant, Australia abject, England embarrassed, though some Down Under preferred reversing that order. Coping mechanisms, eh? We’ve all been there. And yet Australia really do have plenty to cope with right now.It’s right and proper that we salute the Bangladeshi heroes: Hasan Mahmud’s first-innings six-for, a century for Tanzid Hasan and 84 for captain Nazmul Hossain Shanto, and a second-innings five-for from Mehidy Hasan. This was the greatest result in their history, against a team who had deigned to play them only twice in the previous 20 years.But Australia will be doing themselves no favours if they don’t use this result as a chance to reset their team in time for the 2027 Ashes. Clearly, it’s not just England who have questions to answer with less than a year to go before the resumption of Test cricket’s longest-running narrative.The recent Ashes, as has been pointed out on a regular basis these past few days, papered over cracks wider than the one hit by Mitchell Starc to bowl James Vince at the WACA in 2017-18.Against England, only Travis Head, Steve Smith and Alex Carey averaged more than 29, allowing Marnus Labuschagne (28), Cameron Green (24) and Jake Weatherald (22) to huddle together under the radar. Australia have been exposed and need to reset their team ahead of the next Ashes in 2027 England, now under Joe Root, have wasted eight months post-Ashes – shouldn’t allow themselves too much schadenfreudeAnd while Green – to the quiet delight of England fans – has probably cemented his place with his second-innings hundred, Labuschagne’s match double of one (in 35 minutes) and 31 leaves him without a Test hundred in 42 innings, in which time he has averaged 25. Weatherald, meanwhile, has not passed 34 in nine innings since England fed his cut shot at the Gabba.The bowling is another matter. English observers may feel, only half-jokingly, that Bangladesh got off lightly not having to face either Scott Boland or Michael Neser, who hoovered up 35 wickets between them during the Ashes at a rate of one every 44 balls.On the other hand, Boland will be 38 by the time Australia land at Heathrow next summer, and Neser 37, embodying the issues faced by an ageing attack: Nathan Lyon will be 39, Mitchell Starc 37, Josh Hazlewood 36 and Pat Cummins 34.We’ve been here before, of course: the Dad’s Army jibes were bandied about all too easily before England landed in Perth in November, and look how that ended up. But Australia now face a tough decision. Do they give all their old-timers one last chance to win a series in England, or do they use the next few months to refresh and renew?You suspect their hand will be forced, because their schedule is punishing: after the second Test against Bangladesh in Mackay, they face three in South Africa in October, then four at home to New Zealand in December and January, followed immediately by five in India, and the 150th pink-ball game against England at the MCG.If Australia don’t replenish their ranks, they may have no one left by the time they arrive to defend the urn.And that is where England shouldn’t allow themselves too much schadenfreude. After all, they have just wasted the eight months since the Ashes reaching the obvious conclusion that Brendon McCullum was no longer the right man to coach the Test team, and are about to take on Pakistan with a new-not-new captain in Joe Root and a coach, Marcus Trescothick, who is keeping the seat warm for Stephen Fleming.Traditionally, Australia have reacted more swiftly to defeat than England, because their tolerance of failure is much lower, their expectation of excellence a given. Already, Ricky Ponting is making noises about the need for change.You can be sure that, once the Australians have stopped pointing out why Bangladesh’s win showed the Poms how it should have been done, they will steel themselves for a crazy 12 months. Can England say the same?
