Wallabies bring out the double-barrel
The Wallabies meet the All Blacks in Sydney on Saturday.
It will be the first time the pair will have started a Test together, with Wallabies coach Michael Cheika assembling a mobile pack – indicating an intention to play a high-paced game.
Hooper has won the right to the No.7 jersey, with Pocock in No.8.
"Australian rugby is very fortunate to have some quality flanks competing for the No.7 jumper," Cheika said when announcing the line-up on Thursday.
"Both players have been in outstanding form for franchise and country this season and have shown their class in sharing the spot in the first two matches.
"They now have an opportunity to start a Test together which they are very excited about."
Cheika has shaken up his forward pack for the final round – a clash between the only two unbeaten sides in the competition, that also includes South Africa and Argentina.
James Horwill, Dean Mumm and Scott Sio have been promoted to the starting fifteen – with Mumm's rise since returning from Europe forcing Will Skelton to the bench for the first time this season.
In the backs, Bernard Foley and Nick Phipps remain the preferred halfback pairing, while Matt Giteau returns from injury to replace Matt Toomua – Giteau in his first start against New Zealand since 2011. The 93-Test veteran forms a centre partnership with Tevita Kuridrani.
Drew Mitchell, Adam Ashley-Cooper and Israel Folau form a potent back three.
Among the replacements, Kurtley Beale, Toomua and Nic White provide backline cover with Quade Cooper missing out.
In another key milestone for the Wallabies, Scott Sio will make his run-on debut at loosehead prop after a pair of impressive cameos from the reserves bench in Brisbane and Mendoza, and a strong training camp.
"We have been impressed with Scott since joining the Wallabies group and he has worked extremely hard to put himself in this position," said Cheika.
