Bangladesh continued to make the most of home comforts against depleted Australia, doubling their lead in the T20I series with a five-wicket win on Wednesday.
Afif Hossain and Nurul Hasan combined superbly in the run chase as Bangladesh recovered from 56-5 to triumph with eight balls to spare in Dhaka.
The Tigers have now won six on the spin in the shortest format, including their last four on the bounce at the Shere Bangla National Stadium. They have never previously won more than three in a row at any venue in T20 cricket.
Bowled out for 108 in the opening game, Australia managed slightly better in their second outing on the short tour, posting 121-7 after winning the toss and opting to bat.
Mitchell Marsh top-scored with 45 from 42 deliveries, including sharing a 57-run stand with Moises Henriques (30), who hit the only six of the innings.
Shakib Al Hasan and Mahedi Hasan contributed 26 and 23 respectively in the reply, yet Bangladesh looked in serious trouble when the latter was stumped by Australia's stand-in skipper Matthew Wade off the bowling of Adam Zampa.
However, Afif Hossain hit an unbeaten 37 that included a six and five fours. Wicketkeeper Nurul (22 not out) played a supporting role as the duo put on a match-winning partnership worth 56.

Australia's T20I woes continue
While without several regulars - skipper Aaron Finch is out through injury, while David Warner, Steve Smith, Glenn Maxwell and Pat Cummins are not on the trip - Australia have now lost seven of their last seven eight T20I outings.
Indeed, they have been beaten in 14 games in the format since the beginning of 2020 - that is level with South Africa for the most losses for any international team across that period.
Mustafizur magic helps restrict the target
Bangladesh had not beaten Australia previously before this series but have quickly claimed a commanding lead with just three games to go in the series.
Mustafizur Rahman was outstanding with the ball in taking 3-23, while Shoriful Islam (2-27) helped Bangladesh reduce their opponents from 88-2 to 106-7 in the space of four overs.
