Road to 2027: Questions for Australia and South Africa

The halfway point between ODI World Cups is approaching with the next edition to be held in South Africa, Zimbabwe and Namibia in late 2027. In Cairns on Tuesday, Australia and South Africa play their first matches in the format since the Champions Trophy, when they both exited in the semi-finals.

Following that tournament, Steven Smith, Glenn Maxwell and Heinrich Klaasen have announced their retirements from ODIs - the latter from all white-ball internationals - and, as is often the case during World Cup cycles, there is a sense of renewal and rebuilding ahead of the next edition, where Australia will be the defending champions after their triumph in India.

Since the 2023 World Cup, these two sides are at the lower end of the table in terms of ODIs played, and Australia in particular have rarely put their strongest side on the park, either because of workload management or injuries. Pat Cummins, who remains the official ODI captain, has only played two matches since that memorable day in Ahmedabad and will miss this series.

A lot can change over the next two years - there is definitely a chance some players available now don't make it all the way to 2027 - but with an eye on the future, here are some key questions from both sides.

Travis Head, the hero of Ahmedabad, should still be in his prime in 2027 but who will be alongside him at the top of the order is more of a question. Matt Short has had the early running and has shown glimpses, particularly his 63 against England in the Champions Trophy, but will miss this series due to a side injury, which has been worryingly slow to heal.

Mitchell Marsh, who will captain against South Africa in Cummins' absence, enjoyed considerable success opening in the lead-up to, and at, the last World Cup but there is always the lingering question over what his body will allow him to do in the years to come.

In the middle order, Smith's retirement has created a permanent vacancy, which will likely be taken by Cameron Green, who missed the Champions Trophy through injury. Green had a fill-in role at the 2023 World Cup but, providing he has no further setbacks, should be a central figure with bat and ball in 2027.

South Africa's regular ODI captain Temba Bavuma has made no secret of his desire to get to the home World Cup in two years' time, but often caveats that with a clause about what his body will allow. Bavuma has suffered a spate of injuries in the last three years, mostly involving his elbow and his hamstrings, and was hampered by the latter during the recent World Test Championship final and the last ODI World Cup.

He battled through both but continues to bat with heavily strapped elbows and at the age of 35 now, faces the real possibility of not physically being able to get to the 2027 tournament. That could mean his role over the next 12 months or so is a transitional but crucial one. Of South Africa's squad in Australia, Bavuma has the highest ODI average and while he is not known as a quick run-scorer, he provides stability upfront and will be key to their build-up to the next World Cup.

You don't find many cricketers like Maxwell, so this is an interesting one for the selectors. There is the loss of his dynamic, match-changing batting but there is also the vital balance he brought to the side with his offspin. In 2023, he was the second spinner alongside Adam Zampa (having been the lone spinner at the 2015 edition) and finding those overs will be important. It makes Short, who is a handy offspinner, a valuable player while the selectors are clearly keen to develop Cooper Connolly's left-arm spin - he was a late addition to this squad after Mitchell Owen's concussion. Head's offspin remains a useful option while Marnus Labuschagne's legspin has claimed useful wickets in the past year.

Owen and Aaron Hardie, another injury replacement against South Africa, will be vying for an allrounder's position over the next couple of years, while among those outside the current squad, Jack Edwards and Will Sutherland could also come into the mix. They provide seam bowling rather than spin although conditions in southern Africa may work in their favour.

Klaasen's international retirement leaves a power-hitting hole in South Africa's middle order, not least because he has the highest strike rate for the team in ODIs and was named their ODI Player of the Year at the most recent Cricket South Africa awards.

Though David Miller, who is second to Klaasen on the strike-rate charts, remains available, South Africa need to find someone else with six-hitting skills in the middle order and they may be looking to Dewald Brevis as the next big deal. Brevis was the leading run-scorer in the T20I series and, with only ten caps to his name, already holds the record for the highest individual score by a South Africa batter in the shortest format.

His 125 not out in Darwin included 96 runs in boundaries and demonstrated a fearlessness South Africa's coach Shukri Conrad wants his players to live by. The Miller-Brevis combination will not be on show at this series as Miller is currently playing in the Hundred, but the Australia matches are a good opportunity for Brevis, who is uncapped in ODIs, to show what he can do. To date, Brevis has played 25 List A matches, averages 48.40 in the format with a strike rate of 112.10, and was the second-highest run-scorer in the most recent domestic one-day cup, so there's plenty to suggest he has what it takes to make the step up.

Mitchell Starc will be 37 by the next ODI World Cup and Josh Hazlewood, who will play this series, 36. Starc has always said Test cricket will be the format he puts first and Australia have a huge period of that prior to the 2027 tournament. Cummins has tentatively indicated he has eyes on captaining again to defend the title but he, too, will be a key figure in a heavy Test run.

Australia's pace stocks are strong, although Lance Morris' withdrawal from the South Africa series with another back problem is a concern and Jhye Richardson is still a long way off a potential return.

However, Xavier Bartlett has made a very promising start and Nathan Ellis will have the chance to build on his T20 pedigree. It was eye-catching to see the inclusion of Tom Straker and Callum Vidler, recent members of the Under-19 set-up, in the Australia A one-day squad for the India tour next month and it's possible that generation, which also includes Mahli Beardman, starts to emerge in time for 2027, although the following cycle is perhaps more realistic.

Keshav Maharaj and Tabraiz Shamsi were not part of the T20I series as South Africa placed a premium on allrounders, but Maharaj is back for the ODIs, alongside Senuran Muthusamy and Prenelan Subrayen, which suggests there is still some experimentation on the go.

Wiaan Mulder and Corbin Bosch make up the seam-bowling allrounder contingent and will likely compete for one spot in the absence of Marco Jansen, who is recovering from a thumb surgery and is not part of this squad.

Jansen's return will crowd the field even more, which leaves South Africa with a problem of plenty and a question of how to find the best combination. Kagiso Rabada, Lungi Ngidi, Kwena Maphaka and Nandre Burger are the specialist seamers, so there is a lot to work with and getting it right will be key before the title tilt at home.
