Much of the focus on this side of the Tasman has centred on the expected All Blacks' response but that equally intriguing question hangs over Saturday night's Bledisloe Cup showdown at Eden Park.
The Wallabies haven't beaten the All Blacks twice in a row since 2002. Few locals believe that will change, though there is a hint of nervous energy in the air.
However, confidence stems from Michael Cheika springing some major selection surprises, making six starting changes after last week's upset win in Sydney.
Benching David Pocock and showing questionable faith in Quade Cooper were the most controversial calls. With the likes of Wycliff Palu and Will Skelton upfront, the visitors are clearly bracing for an onslaught from the All Blacks' pack, who were upstaged last week.
But Cheika may be guilty of going away from what worked so well for him last week - speed to the breakdown.
The Wallabies also face the task of winning for the first time since 1986 at Eden Park.
Cheika has done everything he can in the psychological department, claiming he doesn't fear failure and guaranteeing Cooper a World Cup spot regardless of whether he cracks under considerable heat on Saturday.
Now we find out if his men have the mental fortitude to back up his sentiments.
In contrast to Cheika's widespread changes, the All Blacks gave those who failed to perform last week the chance to atone. Ma'a Nonu's return from a shoulder knock, Victor Vito's promotion and Sam Whitelock's start a lock were the only tweaks.
Auckland's inclement weather hung about the city on Saturday. Showers have been frequent and promise to play their part with the ground sure to be slippery and handling may be difficult.
Execution will be crucial. The team that takes their chances will prevail.
From a World Cup perspective Nehe Milner-Skudder and Vito have the most to gain for the All Blacks, while Matt Toomua and Henry Speight can enhance their prospects for the Wallabies.
It would also be reassuring to see Dan Carter, in the All Blacks' final test before the World Cup, stamp his authority.
