Bangladesh reduced Australia to 161-4 at the close of the third day in Darwin, with Mehidy Hasan Miraz taking the crucial wicket of Steve Smith.
Australia currently trails by 67 runs in their second innings, while Bangladesh seamer Hasan Mahmud previously claimed a career-best 6-55 in the first innings.
Josh Hazlewood reached 300 Test wickets during the match, but Bangladesh's first-innings total of 426 has put the visitors in a strong position to secure their first-ever Test win in Australia.
