Spinner Mehidy Hasan Miraz took the key wicket of Steve Smith to reduce Australia to 161-4 after the third day of the first Test in Darwin on Saturday and move Bangladesh closer to a historic upset. 

At stumps, Australia trailed by 67 runs in their second innings, with Cameron Green on 43 and Alex Carey on 19. After being dismissed for 426 shortly after lunch, Bangladesh seamer Hasan Mahmud stunned Australia when he claimed both openers cheaply.
