The Wallabies and All Blacks will contest the third Bledisloe Cup test at Perth's Optus Stadium on September 5 after the New Zealanders pulled out of the original date, citing Covid-19 concerns.
The All Blacks' last-minute decision not to travel to Perth for the final game of the series sent Aussie pundits into a frenzy last Friday.
Coach Dave Rennie said he was "bloody angry" at the cancellation, which he said his players found out about on social media.
On Thursday, following discussions between Rugby Australia, New Zealand Rugby, Optus Stadium and the Western Australian government, the new date was announced.
"I want to thank Premier Mark McGowan, Deputy Premier Roger Cook, Tourism Minister David Templeman, Sport Minister Tony Buti and the rest of Western Australian government, as well as Mike McKenna at Optus Stadium for their consistent and solution-orientated approach in working with us to secure the date in such a short time frame," Rugby Australia CEO Andy Marinos said.
