Hasan Mahmud takes 6-55 as Australia bowled out for 198

Hasan Mahmud claimed career-best figures of 6-55 to bowl Australia out for 198 on the opening day of the first Test in Darwin. Steve Smith top-scored with 71 after a reprieve early on, but Bangladesh's pace attack suffocated the hosts on a tricky surface.

Mahmud became the first Bangladesh bowler to take six wickets against Australia in Test cricket. While he was getting among the runs, Taskin Ahmed notched 300 international wickets during the innings — a milestone that underscores how long Bangladesh's attack has been grinding away.

Bangladesh reached 96-1 at stumps, trailing by 102 runs. They've seized control of day one and hold all the momentum heading into day two.
