"I had the responsibility to get us off to a good start and set up the chase", Finch said.
It was a clinical effort from the bowlers, in particular Imad Wasim, who on his return to worldwide cricket after more than a year rattled the Australian top-order to return figures of 3/20 in his four-over spell.
"I take full responsibility for that".
Australia's told was their joint third-lowest in T20Is, behind their 79 against England at Southampton in 2005 and 86 against India in 2014. We were outplayed. We tried to hit the ball too hard.This team hasn't been together for a long time and in future we will be better.

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. Babar Azam scored his third consecutive half-century but that is where the problem starts. "I think all in all, our bowling performance was pretty good".
Everything was going right for Pakistan, including Hasan's spectacular outstretched catch on the boundary to see off Adam Zampa.
In the first six overs Pakistan took six wickets and conceded just 26 runs, making it the best bowling powerplay ever in a T20 worldwide.
On the other hand, Australian captain Aaron Finch said the defeat was embarrassing.
Mohammad Hafeez (39) and Azam shatred a 73-run stand for the second wicket and dominated the Australia spinners in the middle overs before the visitors pegged the hosts back by picking up five wickets in 10 delivers and just three runs.
Australia named an unchanged XI from Monday's seven-wicket victory over the UAE, again omitting Test squad members Mitch Marsh, Nathan Lyon, Peter Siddle and Mitchell Starc.
For Pakistan, they'll have fewer selection considerations to make ahead of the second T20I at Dubai on Friday if any at all.
