Well done Bangladesh👍🏽 #BANvAUS— Farveez Maharoof (@farveezmaharoof) August 3, 2021That’s a solid win for Bangladesh. In the end Aus had just as much trouble playing cutters as they did spin. Completely outfoxed by the Bangladesh attack. 6 T20games in on this tour can’t really talk about rustiness. #BANvAUS— Melinda Farrell (@melindafarrell) August 3, 2021What a win by Bangladesh and What a Remarkable comeback by Bangladesh. Bangladesh only scored 131 runs but they won by 25 runs against Australia in First T20I match. Nasum Ahmed is the Star for Bangladesh, picked 4 wickets in 4 overs. Brilliant display of Bangladesh. #BANvAUS pic.twitter.com/GIzz2qKLEe— CricketMAN2 (@man4_cricket) August 3, 2021This is Bangladesh Cricket Team.

There's 160 million Bangladeshis, if you play in the first XI, you gotta be really tough, don't you?#BANvAUS #Bangladesh pic.twitter.com/5bFf3bchEr— Midhun M Menon (@Mid_On_) August 3, 2021HISTORY: Bangladesh beat Australia in 1st T20i at Dhaka that too without Mushfiqur Rahim and Tamim Iqbal#BANvAUS— Najeeb ul Hasnain (@ImNajeebH) August 3, 2021One at a time @BCBtigers!! Believe #BANvAUS #T20Iseries— Shrinivas (@WhoShriniC) August 3, 2021Nasum Ahmed picked 4/19 to guide Bangladesh to victoryAsked to bat first, Bangladesh banked on Mohammad Naim to get off to a steady start on a sluggish wicket. However, they struggled and limped to a meager 37/2 in seven overs. Shakib Al Hasan and skipper Mahmudullah then added a crucial partnership before Afif Hossain provided some late impetus. He scored 23 off 17 balls to propel Bangladesh to 131/7, which proved to be too much for the Aussies in the end.Chasing a moderate total, Australia got off to a poor start and were left reeling at 11/3 after 2.1 overs. All-rounder Mitchell Marsh held tight at one end but kept losing partners at the other. He scored 45 off 45 deliveries, which was ultimately not enough for the visitors to get over the line.Nasum Ahmed, who is still in the early stages of his international career, picked up four wickets while Mustafizur Rahman and Shoriful Islam returned with two apiece as Australia fell short by 23 runs.Speaking at the end of the match, Bangladesh skipper Mahmudullah credited the bowlers for putting up a brilliant show:"We had a team talk during the halfway stage and said that we were 10 runs short, so we have to field well and put more effort. That's what you need while defending low totals and have attacking mindset. They are a very good side and we need to tick the boxes we failed today in the coming games. The hunger needs to be there to win every game for Bangladesh. I am not over the top at the moment, it was a match, we won and it is gone now, looking forward to tomorrow's game."The second match of the five-match series is on August 4 (Wednesday) in Dhaka.
