The visitors continued to attack with wickets at regular intervals with just Steve Smith showing some resilience for the former World Test Champions.
Australia eventually folded out for 198 with player of the match Mahmud delivering a memorable spell (6/55) that set up things nicely for Bangladesh.
Bangladesh's reply in the first innings with the bat was led by opener Tanzid Hasan's magnificent century (101 off 197 balls) combined with captain Najmul Hossain Shanto's 84 off 126 balls.

Requiring just 57 runs to win, the visitors got there with nine wickets to spare marking a significant moment in Bangladesh cricket.
The historic win came up after Bangladesh were skittled out for 54 runs in the warm-up match against Cricket Australia XI.
Shanto, who was determined to put up a fight against a challenging Australia side, credited the team after the momentous victory.
"Very happy, proud of myself and the way the boys played. We did lot of hard work," he said during the post-match presentation, calling it the biggest Bangladesh win across formats.
"Earlier, five years ago, pacers didn't want to play Tests. But we've been playing lots of Test cricket and they are giving importance to Test format.
"They want to play, want to perform, want to be world-class. That is the mindset they now have.
"This is the biggest win so far for Bangladesh in any format. Going forward, we want to do something special in the future."
