Two days to go.
England's opening match in Australia starts on the morning of Friday.
With the help of cricket statistics experts, we examine where the highly awaited Ashes series in years could be decided.
Batsmen on each side of the Ashes divide might be wondering why they are even planning to show up.
Much of the build-up has centred around the perceived difficulty of scoring runs, particularly for the opening match on a Perth pitch described as a "lush, challenging surface".
Regarding batting in Australia, especially against pace bowling, no nation has been more difficult in which to accumulate runs over the last five years.
There are two reasons for this: wickets and cricket balls.
Taken as a collective, the pitches produced in Australia have been shown to be the fastest, most bouncy and among the least predictable in the world.
Speed and variable bounce are the ideal combination for difficult batting conditions.
A long-standing narrative from English cricket describes the Kookaburra ball used in this country as a ineffective weapon for a pace bowler.
A new version of the Kookaburra was introduced six years ago, leading to more seam movement.
Seam is a more significant asset than swing in this country.
After the new ball's introduction, fast bowlers are conceding 25 runs per wicket in Australia.
Test cricket is about solving problems.
When bowlers dominate, batsmen's contributions can be the difference, and vice-versa.
If this Ashes be dominated by the ball, a batter could have the chance to be the key factor between the two teams.
On this occasion, England have arrived in Australia with their pace attack mostly fit, while the hosts are the ones hit by injuries.
Captain Pat Cummins will be absent for the first Test with a back injury, and Josh Hazlewood is on the sidelines for an unknown period because of a hamstring injury.
Pat Cummins, Josh Hazlewood and Mitchell Starc were first paired as a trio for the 2017-18 Ashes.
Since then, they have taken together 81% of the dismissals taken by Australia pace bowlers in matches in Australia.
The Australian team have seldom needed alternatives because of the effectiveness and durability of the 'big three'.
On the occasions Australia have required support, Boland has been sensational, taking 62 wickets in 14 Tests at an average under 17.
Aside from Boland, other bowlers of the backup squad have stepped up.
Neser, Jhye Richardson and James Pattinson all average below 30 in home Tests.
The most recent occasion Australia entered a home Test without both key bowlers, and lost, was in 2012.
The past two times they have played at home without the pair, they have won by a combined 694 runs, featuring a victory against England in the Adelaide Test previously.
In infrequent cases Australia have had to look beyond their superstar pacemen, outcomes have not been affected – England should pay attention.
Remember when England could not find an opener to partner Alastair Cook?
Sir Chef changed partners faster than Watford go through managers.
No more.
Ever since Ben Duckett and Zak Crawley were united at the top of the England order at the close of 2022, no opening pair in the world has scored more runs together.
Their success as a combination has been a reason in Crawley being backed through some inconsistent times.
Crawley, who famously struck the initial delivery of the previous Ashes for four, has also been recognized as having the game for Australia.
His batting average increases when the pace increases.
By contrast, the Australian opening lineup is in a ongoing change, still seeking to fill the David Warner-shaped hole.
Following Warner's retirement at the start of 2024, Usman Khawaja has batted with five different partners in 15 Tests.
Yet to debut Weatherald looks set to become the sixth in 16 Tests on the opening day, giving Australia an left-handed opening pair.
It's not only the opening pair that has caused problems for Australia.
Marnus Labuschagne, Australia's long-term number three, was shifted to open for the World Test Championship final, then left out completely.
Domestic form has earned him a recall, most likely back at three.
In seven Tests in the current year, Australia's top three have a combined average of 25.37.
Only the top threes of Zimbabwe and West Indies have performed worse.
Between two closely matched sides, there is one area where Australia are clearly stronger – spin.
Nathan Lyon of Australia, with 562 Test wickets of him, is among the best finger-spin bowlers to play the game.
Shoaib Bashir of England is a somewhat successful gamble, looking short of form after a finger injury, while Jacks is mainly a batsman.
It makes sense for the home team to want Lyon at the forefront, but spin bowling has been incredibly hard work in Australia for the past 10 years.
During that period, spinners have averaged nearly 44 in Australia, though Lyon's record holds up well compared to the difficulties of visiting tweakers.
Lyon's other issue is actually bowling enough overs.
Remember the effectiveness of fast bowling?
It is reducing the time Lyon has with ball in hand.
In the 2017-18 Ashes here, Lyon was averaging 50 overs per Test.
In the previous year, in five Tests against India, it was half that number.
Test matches in Australia are lasting about 25% less time since the updated ball was introduced, meaning Lyon has fewer opportunities to make an impact.
England have a unfortunate tendency of being beaten in an overseas Ashes before Father Christmas has set off.
Traditionally, the series began in the Gabba, where they have not won since 1986.
In recent times, that has been followed with a floodlit Test in Adelaide Oval.
England have one win in seven day-night matches worldwide, while Australia have won 13 out of 14.
Then comes Perth, a city England have visited on 14 occasions since 1970 and emerged victorious only once, against a depleted Australia in 1978.
On this tour, the initial three venues on the tour are the same, only in a rearranged order and under altered conditions.
The Perth Test stages an Ashes opener for the first occasion, not at the famous Waca – site of past English struggles – but the shiny new Perth Stadium.
It remains a tough assignment, though one the visitors tackle with no past burdens.
The Gabba is the location for the second match, the day-night fixture.
The last time Australia played a day-night Test at the Gabba, they were stunned by the West Indies.
Similarly, the Aussies 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 were defeated once, to India, in 2018.
The revised fixture list gives England a fresh attempt at starting an away Ashes well, albeit with pitfalls.
The home side have secured victory in four out of five matches played at Perth Stadium, though the one defeat came in the most recent match – against India the previous year.
Every Test at the new venue has been claimed by the team batting first.
The English often overthink floodlit Tests, when statistics indicate the pink cricket ball does not perform much differently from its red counterpart.
