They won by 20 runs.
With Australia losing five wickets for 90 runs in the first session, it was an uphill battle from that point on and Bangladesh continued their resurgence, having earlier beaten England and Sri Lanka in 2016/17.
Smith said the 45-run first-innings deficit and the 155-run partnership between Shakib and Tamim Iqbal on day one after Bangladesh had been 3-10 inside the first half-hour of the match were the two major factors in the loss. Shakib also scalped five wickets in the first innings which included crucial dismissals of Matt Renshaw and Glenn Maxwell.
Bangladesh scripted history against Australia on Wednesday and their biggest hero, Shakib Al Hasan was the architect. David Warner was the only batsman in the Australian lineup who stood between Bangladesh and their maiden Test win over Australia. David Warner played a lone hand for the visitors. Tamim brought up his 24th Test half century, and second in the match.
"Naturally our spinners can do much better than they did and it would release pressure from Shakib", he said. "He was brilliant. We have been consistent in home conditions".
Cummins belted offspinner Mehedy Hasan for two sixes in one over to reduce the deficit but it was all over when Taijul Islam trapped Josh Hazlewood lbw for a duck. "Not many have been watching us but we were quietly doing our job".
Mushfiqur, meanwhile, pointed to Australia's tactic of slowing down proceedings and even resorting to sledging of their tailenders as a sign of being on the back foot. Umpire Aleem Dar turned down a muted appeal from the bowler before skipper Steve Smith decided on a review. I think we fought neck and neck till the fourth day, but I will say they were ahead of us today [yesterday].
Pat Cummins scored an unbeaten 33 down the order to inject some drama but it was not enough as Australia were all out for 244. "And what have us confidence", he said in mother tongue.
"They [Australia] had the aggression but at the same time they also realised how aggressive Bangladesh can be, not only while playing but also in our body language. It's the mindset that changed, and that made us believe that we can win".
