The Wallabies have stunned world champions New Zealand and set themselves up to bring home the Bledisloe Cup with an inspired 47-26 Test win in Perth.
The Australians were given little chance of knocking off their arch-rivals, but delivered their best performance in years to make a statement with the Rugby World Cup starting next month.
They must crack their first win in Auckland since 1986 to secure the prized trans-Tasman trophy for the first time in 17 years.
"A few things went our way but I was really pleased for the lads," Wallabies coach Michael Cheika said. "They've been working hard so it was a nice little reward for them."
The All Blacks were forced to play the entire second half with 14 men after lock Scott Barrett was sent off in the 40th minute by French referee Jerome Garces for making contact with the head of Wallabies skipper Michael Hooper with his elbow and shoulder.
While that call will be debated, Australia already had their tails up after a dominant first half and took a 16-12 lead into the break.
Cheika said the fact that they faced an undermanned All Blacks didn't take any gloss off the win.
"Not a chance," he said.
"When they've got 15 on the field it feels like 20 so when they've got 14 it still feels like 17 or 18 as they have so many threats.
"It's not like they weren't scoring tries."
It was difficult to pick the Wallabies' best with Hooper everywhere, halfback Nic White a handful and the entire forward pack deserving a pat on the back.
James O'Connor, starting his first match in six years, also booked his ticket to Japan as he set up a try and gave the attack plenty of options.
The Wallabies extended the margin to 26-12 early in the second half with giant flanker Lukhan Salakaia-Loto scoring before Samu Kerevi set up the second.
The bustling centre ran over the top of star All Blacks fullback Beauden Barrett before offloading to White.
Barrett exacted some revenge six minutes later when he darted through some flimsy Wallabies defence, with the conversion closing the gap to seven points.
But that was as close as the undermanned Kiwis could get as the scoreboard ticked over for Australia.
Reece Hodge scored his second try while fellow winger Marika Koroibete, who was equally as dangerous all night, also crossed.
Fullback Kurtley Beale iced the win with their sixth try in the 80th minute to allow the celebrations to begin.
In an extra sweetener, the All Blacks could surrender their world No.1 ranking to Wales for the first time since 2009 should the Welsh beat England later this weekend.
All Blacks coach Steve Hansen said his team were their own worst enemy, lamenting their poor discipline.
"I'm disappointed but Australia deserved the win as they were the best side on the day," Hansen said.
"The red card didn't help us but we didn't help ourselves either.
"Our discipline was poor early in that first half and we missed 20 tackles out of 90 in the first half.
"So they're all things we've got to fix up."
