Dubai: Top-ranked Pakistan put in another clinical performance to beat Australia by 33 runs in the third and final T20I and completed a 3-0 series sweep on Sunday.

Australia finished their disappointing tour without a win as they also lost the Test series 1-0 after narrowly escaping with a draw in the first Test.

Babar Azam (50) notched his second half century of the series off 40 balls as Pakistan scored 150/5 after captain Sarfraz Ahmed won the toss and opted to bat.

The Australian chase fell off for the third successive time and were bowled out for 117 in 19.1 overs with leg-spinner Shadab Khan grabbing 3/19 and Shoaib Malik taking three smart catches in the deep.

"Boys have worked hard and the result is just the reward," said Ahmed, who won his 10th consecutive T20I series.

Shadab could have finished with at least two more wickets had he not dropped D'Arcy Short off his own bowling and Faheem Ashraf dropped a sitter from Andrew Tye.

Azam and Sahibzaba Farhan (39), who was given his first game of the series, gave Pakistan a solid start of 93 before both fell in successive overs.

Farhan struck three sixes and two fours before he holed out in the deep while Azam got a big inside edge to Tye after hitting five fours and a six.

Australia came back through wrist spinner Adam Zampa (1/25) and a tidy spell of 0/27 by Short before Mohammad Hafeez (32 not out off 20 balls) and Malik (18 off 12) lifted the total.

Alex Carey gave Australia a whirlwind start of 20 when he smashed left-arm spinner Imad Wasim for two sixes and two boundaries in the first over.

But Australia's top order faltered for the third time in a row through some reckless shot selection.

Carey tried to turn around Hafeez's first delivery and got a leading edge; Chris Lynn swept Shadab's first ball and was caught at midwicket; and Glenn Maxwell played a needless big shot to give Malik one of his three catches.

Ben McDermott (21) was run out for the third time in the series and Mitchell Marsh, who also scored 21, gave an easy catch at long on.
