The five debutants include Queensland trio Michael Neser, Brendan Doggett and Marnus Labuschagne, Travis Head of South Australia and Aaron Finch of Victoria.
"There was a significant change in our testing team, due to the lack of availability of several key players," said coach Trevor Hohns.
"That said, we firmly believe that the selected team is up to the challenge that is coming and is able to play against a cricket brand that can perform well in this series against Pakistan.
"It's a mix of experienced players who have a significant amount of trial or first-class cricket, and a number of younger players that we trust are ready for the test field."
Three spaces of first order were vacant by Smith, Warner and the absence of Bancroft. Starter Matt Renshaw, who was ejected before the ashes last year but returned for the final test in South Africa, fills one of them after an outstanding season in Sheffield Shield.
– Concentration art –
Aggressive Finch, best known for his exploits in the shortest form of the game, was also included and is inclined to open the batting with Renshaw.
Coach Justin Langer said Finch was a natural leader and deserved the opportunity to demonstrate his credentials at the Test level.
"He is one of the main leaders of the group and I know he has waited a long time to be part of the team.
Hussey or Brad Hodge or George Bailey, he can also have an impact on the test cricket, "he said.
In a relief for the coaches, the experienced Shaun Marsh was declared fit after recovering from a shoulder injury that forced him to return home in July from a county cricket season with Glamorgan.
An Usman Khawaja, an off-road Mitch Marsh and Head or Labuschagne should complete the middle ranges.
Peter Handscomb lost the opportunity after a poor performance in Australia today A tour of India, and multi-level hitter Glenn Maxwell was a surprise omission, given his practical offside option.
Langer said that Maxwell needed to score more big scores regularly to be in the fight.
"I would love to see Maxy score more and we have talked a lot about the art of concentration and looking at the ball like a hawk," he said.
"If you do it more regularly, you'll win more hundreds and you'll be much more eligible for the test cricket."
Veteran Mitchell Starc will lead the bowling attack with Neser or Doggett, his potential new ball mate.
And there was a retreat after two years for the fast Siddle warhorse in the back of its red-hot form in England this year with Essex.
"His experience will be crucial for this bowling group, and we know he is a warrior who can play the kind of long, tight spells that may be required in the conditions we expect to face," Hohns said of the 62-man veteran. .
Nathan Lyon, Jon Holland and lefty Ashton Agar occupy the slot machines with captain Tim Paine behind the wicket.
The first Test will be held in Dubai from October 7 and the second in Abu Dhabi from October 16.
