England arrives in Brisbane with a fast-bowling attack widely regarded as its strongest in a decade and an opening pair whose attacking intent has reset the rhythm of Test cricket. The Australian top order, in the middle of a generational rebuild, will be tested from the very first session.

Selectors have settled, after some indecision, on an opening combination that emphasises temperament over flair. The middle order is more familiar, but every player in it — including the captain — is responding to questions about form rather than asking them.

Where the series is likely to be won

On past form, the series turns on the second Test, in Adelaide. Australia's record at Adelaide Oval is strong; England's is, charitably, mixed. A 2-0 lead going into Adelaide would be commanding. Anything less, and the series will run to the fifth Test in Sydney.

The pitch in Brisbane has, in the lead-up, played truer than expected. Reports from training suggest pace and bounce, but with less seam movement than the visiting bowlers will have hoped for. That, more than any tactical adjustment, may be the series' first quiet pivot.

What to watch in the first session

If the Australian openers can survive the first hour at the cost of a single wicket, the day belongs to the home side. If England takes two in the first session — particularly if they take both openers — the series tilts immediately.

"The Ashes is decided in the first hour of the first day, more often than anyone admits."

A series with stakes beyond the trophy

Beyond the Ashes urn itself, the series carries weight for both squads' Test futures. England's coach has spoken openly about wanting to define the next era; the Australian captain has spoken about closing this one with dignity. The first ball is bowled at half past ten on Thursday morning.
