Surfaces, Balls and Reserves – Where the Ashes Will Be Decided
Two days to go.
The English side's first Test in Australia gets under way on Friday morning.
With the help of CricViz, we examine where the most eagerly-anticipated Ashes series in years could be determined.
It's tough to make runs, isn't it?
Batters on both teams of the Ashes divide might be wondering why they are bothering to show up.
A lot of the pre-series discussion has focused on the perceived challenge of scoring runs, particularly for the opening match on a Perth pitch described as a "green monster".
Regarding batting in Australia, particularly against fast bowling, no country has been more difficult in which to accumulate runs over the past five years.
There are two reasons for this: wickets and balls.
Overall, the surfaces prepared in Australia have been shown to be the quickest, highest bouncing and among the most inconsistent in the world.
Pace and variable bounce are the perfect recipe for difficult batting conditions.
A common belief from England's cricketing circles paints the Kookaburra ball used in this country as a ineffective weapon for a pace bowler.
An updated model of the Kookaburra was introduced six years ago, resulting in increased seam movement.
Seam bowling is a much bigger weapon than swing bowling in this country.
After the new ball's introduction, fast bowlers are averaging 25 runs per wicket in Australia.
Test match cricket is about solving problems.
When the ball is on top, performances of batters can be the difference, and the reverse is true.
Should this series be bowler-dominated, a batsman could have the chance to be the key factor between the two teams.
What's going on with the Australia seamers?
For once, England have arrived in Australia with their pace attack largely intact, while the home side are the ones hit by injuries.
Captain Pat Cummins will be absent for the opening match with a back injury, and Josh Hazlewood is unavailable for an unspecified time because of a hamstring injury.
Cummins, Josh Hazlewood and Starc were first united as a three-pronged attack for the 2017-18 series.
Since then, they have combined to claim 81% of the dismissals taken by Australia pace bowlers in matches in Australia.
The Australian team have seldom needed alternatives because of the success and durability of the 'leading trio'.
On the occasions Australia have needed a back-up, Boland has been outstanding, taking 62 wickets in 14 Tests at an average under 17.
In addition to Scott Boland, other members of Australia's supporting cast have performed well.
Michael Neser, Jhye Richardson and Pattinson all average under 30 in domestic Tests.
The last time Australia entered a home Test without Cummins and Hazlewood, and were defeated, was in 2012.
On the last two occasions they have competed in Australia without the duo, they have won by a total of 694 runs, featuring a win against England in Adelaide previously.
In infrequent cases Australia have had to look beyond their superstar pacemen, results have not been affected – The tourists should take heed.
Challenging Openings
Recall the time England could not find an opener to partner Alastair Cook?
Sir Chef went through partners more quickly than Watford change coaches.
Not anymore.
Ever since Duckett and Zak Crawley were united at the England opening slot at the close of 2022, no opening pair in the world has produced more runs together.
Their success as a combination has been a factor in Crawley being supported through some inconsistent times.
Crawley, who famously struck the first ball of the previous Ashes for a boundary, has also been recognized as having the game for Australia.
His average rises when the bowling gets faster.
By contrast, the Australian opening lineup is in a ongoing change, still seeking to fill the David Warner-shaped hole.
After Warner's departure at the beginning of 2024, Usman Khawaja has batted with five different partners in 15 matches.
Uncapped Weatherald appears likely to become the sixth in 16 Tests on the opening day, giving Australia an left-handed opening combo.
It's not only the opening pair that has caused problems for Australia.
Marnus Labuschagne, Australia's regular number three, was shifted to open for the WTC final, then left out completely.
Home performances has earned him a recall, most likely returning to number three.
Across seven matches in 2025, the Australian top order average a collective of 25.37.
Only the opening trios of Zimbabwe and the West Indies have done worse.
Spin war
For two so evenly-matched teams, there is a single department where Australia are clearly stronger – spin bowling.
Nathan Lyon of Australia, all 562 Test wickets of him, is one of the finest finger-spinners to ever play.
England's Shoaib Bashir is a somewhat successful gamble, appearing out of touch after a broken finger, while Jacks is primarily a batter.
It makes sense for the hosts to want Nathan Lyon at the front, but spin bowling has been incredibly hard work in Australia for the past 10 years.
During that period, slow bowlers have averaged nearly 44 in this country, albeit Lyon's record largely stands up compared to the struggles of visiting tweakers.
Lyon's other issue is physically getting on to bowl.
Recall the potency of pace bowling?
It limits Lyon's time with the ball.
In the 2017-18 Ashes here, Nathan Lyon was averaging 50 overs per Test.
In the previous year, in five matches against India, it was only half as many.
Test matches in Australia are lasting about 25% less time since the updated ball was introduced, meaning the spinner has fewer opportunities to influence the game.
Right place, right time?
England have a unfortunate tendency of being defeated in an away Ashes before Father Christmas has set off.
The series began in Brisbane, where they have not won since 1986.
Recently, that has been followed by a floodlit Test in Adelaide.
England have one win in seven pink-ball Tests worldwide, while Australia have triumphed in 13 out of 14.
Then comes Perth, a city England have visited on 14 occasions since 1970 and won only one time, against a depleted Australia in 1978.
On this tour, the first three stops on the tour are the identical, only in a different order and under different circumstances.
Perth hosts an series opener for the first occasion, not at the fabled Waca – scene of many an England humbling – but the modern Perth Stadium.
It is still a tough assignment, though one the visitors approach with no historical baggage.
The Gabba is the venue for the second Test, the day-night fixture.
The last time Australia played a pink-ball Test at the Gabba, they were surprised by the West Indies.
Similarly, the Australians are now not used to playing daytime Tests at the typical floodlit ground Adelaide.
In the two red-ball matches played in the Adelaide since 2014, Australia lost one, to India, in 2018.
The revised fixture list gives England a new opportunity at beginning an overseas series positively, albeit with pitfalls.
The home side have won four of the five Tests played at Perth Stadium, though the one defeat came in the latest game – against India the previous year.
Every Test at the new venue has been claimed by the team batting first.
England often overthink floodlit Tests, when data indicate the pink cricket ball does not perform much differently from its red counterpart.
