Although Nathan Coulter-Nile (34 off 29 balls) and Ashton Agar (19 off 23 balls) saved their team from total embarrassment with a 38-run partnership, they never scored at a rate that would have remotely concerned Pakistan.
Adam Zampa and Andrew Tye both fell for single figures and Coulter-Nile was last man out when he was bowled by Shadab Khan as the Aussies were dismissed for just 89 in 16.5 overs.
Imad Wasim, playing in his first worldwide match in almost a year caused havoc with his slow left-armers dismissing both openers in the first over and unveiling his new Cristiano Ronaldo-inspired celebration in the process. "Opening the batting, it's my responsibility to get us off to a good start and set up the chase there". He then said "I take full responsibility for that".
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 worldwide for a year.
"It's just obviously not doing the basics".
Their T20 skipper Aaron Finch said his team was motivated enough to win the series.
Virat Kohli breaks Sachin Tendulkar’s record as fastest to 10,000 ODI runs
I am just happy that I have been able to play for this long and hopefully many more years to go. Kohli reached the milestone in his 205th ODI innings, 54 innings quicker than Tendulkar .
Pace duo Billy Stanlake (3-21) and Andrew Tye (3-24) did the bulk of the damage, with Stanlake using his pace and height to devastating effect.
His batting lineup, without the suspended Steve Smith and David Warner, was arguably their strongest available with Finch, D'Arcy Short, Glenn Maxwell and Lynn providing some power hitting at the top of the order.
The esteem with which T20 cricket is held in the world game was highlighted with the unveiling of the biscuit-shaped trophy that is up for grabs in Australia's upcoming T20 contest with Pakistan.
Earlier, Pakistan were lifted by Azam and Mohammad Hafeez (39) as they added 73 for the second wicket in quick time.
Wasim was named the Player of the Match for his bowling performance.
Finch also told that their performance in the first T20I was so poor that they should now consider a change in the squad for the second match.
