Rebels hooker Jordan Uelese has bolted into the Wallabies squad for the Bledisloe Cup, with injuries having a major say in the 34-man group.
Waratahs hooker Tolu Latu has played little part in training after a neck injury, with Uelese's impressive showing in camp putting him right into Test contention.
Uelese is one of five Rebels in the camp, with the Waratahs having nine representatives, Queensland seven and the Brumbies and Force six.
Kurtley Beale, likely to be the first-choice 12, is set for a Wallabies return, though Cheika has kept on all bar one of his squad centres for the first Test
Both Beale and Samu Kerevi have been working their way through injury, with Cheika keeping his options open in the department.
Japan-bound Campbell Magnay is the only midfielder omitted from the extended squad, with Force duo Bill Meakes and Curtis Rona one step closer to Test debuts.
Cheika has kept veteran lock pair Rob Simmons and Kane Douglas in the mix, with Brumbies captain Sam Carter dropping out of the squad.
Sean McMahon's return to the Wallabies fold has squeezed out flanker Richard Hardwick, despite the Force youngster's promising June form.
Cheika has opted for Force tighthead Tetera Faulkner over Queensland's Taniela Tupou and Sef Faagase in the front row.
Will Genia and Bernard Foley have been appointed the side's vice-captains, deputising for Michael Hooper.
"Will and Bernard are starting to find their voice as real leaders within the team and will be valuable assets to the captain in Michael," coach Michael Cheika said.
"They (Will and Bernard) have been selected because both of them are hungry to win and are prepared to keep both themselves and their team to the high standards required to take the Wallabies to be the best."
Genia has served as Wallabies captain four times and been deputy in the past but has not had a formal role since before the 2015 World Cup.
"I really love this Wallabies team, and love any chance I get to wear the gold jersey but to be named vice-captain really is an honour, " Genia said.
I want to thank Cheik (Michael Cheika) for putting that trust in me – and I will be doing everything in my power to support Hoops (Michael Hooper) in whatever way possible alongside Bernard."
Foley has played 45 Tests for the Wallabies but this will be his first official stint as a formal leader.
“It’s a huge personal honour to be vice-captain of this team and I am looking forward to working with all the leaders in this team to ensure the Wallabies elevate to the best we possibly can be," he said.
“Hoops (Hooper) is a remarkable leader, and I believe with the other leaders in the team we can complement his style and assist him in that responsibility."
The Wallabies squad will link up on Sunday in the Hunter Valley, ahead of the August 19 Bledisloe opener.
