Pakistan ended on a decent 155-8 off their 20 overs at a rate of 7.75 runs per over.
Australia-Pakistan hasn't had many interactions in the shortest format of the game.
The first T20I between Pakistan and Australia will begin at Sheikh Zayed Cricket Stadium in Abu Dhabi at 09:00 pm PST.
Nathan Coulter-Nile top scored for Australia with 34 and helped the Aussies go past their previous lowest T20 score of 79 made against England at Southampton in 2005. "Pakistan played very well against us in July", said Finch.
"That powerplay was horrific.it was like a vehicle crash in slow motion".
Each of Australia's top four batsmen were bowled and Chris Lynn (14) was the only member of the top six to reach double digits as the tourists lost six wickets in the powerplay to underscore their shocking start to the three-match series.
Australia's hopes of taking the lead in the three-match series were soon over as they made a horrendous start to their reply, slumping to 22-6 with spinning all-rounder Imad taking 3-20 in his first global for a year. Opening the batting, it's my responsibility to get us off to a good start and set up the chase there. Our fielding was slightly sloppy, then the batting was bad.More news: Bollywood heartthrobs Deepika and Ranveer announce wedding date
Finch said changes would be strongly considered for Friday's second T20 in Dubai, which will also host the third and final game on Sunday.
The rapid Stanlake was rewarded for a hostile opening spell when he bounced out Fakhar Zaman, but a second-wicket stand of 73 between Babar and Mohammad Hafeez put Pakistan in a strong position.
Paceman Faheem Ashraf and Shaheen Afridi both took two wickets apiece for Pakistan.
It was left to Azam to keep one end intact during his sixth T20 half-century while Hasan used the long handle effectively, hitting two boundaries and a six in a handy 17 off eight balls to help add 41 in the last five overs.
Australian were six down with just 22 runs on the board which not only tells you the story of the match and largely about the state of the batting unit.
"Our bowling attack is good so we back them to defend a total".
Australia and Pakistan are scheduled to face each other in a three-match T20I series from October 24 to 28.
