Australia has made significant headway into Bangladesh's meagre total of 197 all out at stumps on day one in Chittagong.
The tourists have enjoyed few troubled moments in reply, reaching 1-76 at the close of play to trail by 121 runs.
Matthew Hayden and Phil Jaques - making his second Test appearance after debuting against South Africa in the Boxing Day Test - added 67 for the first-wicket before the powerful Queenslander was caught in the deep by substitute fielder Alok Kapali for 29.
Jaques remains unbeaten on 38, passing his previous highest score and is now on the lookout for his maiden Test half-century.
Meanwhile, nightwatchman Jason Gillespie blocked his way to five not out.
Bangladesh's total of 197 could have been so much lower after Gillespie - in his day job - struck early to reduce the Tigers to 3-17.
The top order were guilty of too many loose shots as they set out to recreate the remarkable first day of the opening Test when they reached 5-355 at stumps.
The South Australian paceman grabbed the wickets of Javed Omar (two), Shahriar Nafees (no score) and captain Habibul Bashar (nine) to complete a dynamite five-over spell of 3-11 although in truth Nafees and Bashar contributed to their downfalls.
Mohammad Ashraful (six) then played a poor shot off Shane Warne which only served to give Hayden catching practice at first slip when the Bangladeshis really needed to keep its composure.
Aftab Ahmed and Rajin Saleh staged a mini-recovery by adding 61 runs for the fifth-wicket before the all-rounder was given out by South African umpire Ian Howell in controversial circumstances.
Ahmed appeared to glance Warne's flighted delivery onto his boot and up into the hands of wicketkeeper Adam Gilchrist.
But after a long review by the third umpire, Howell ruled the batsman not out despite TV cameras clearly highlighting otherwise much to the chagrin of Ricky Ponting and the Australians.
Only after prompting by Ponting did the on-field umpires ask for the decision to be reconsidered and Ahmed was curiously sent on his way for 18.
Saleh (71) - the only Bangladeshi to offer any true resistance - then fell to a beautiful piece of bowling by Stuart MacGill, clean bowled as he attempted to pull the leg-spinner through the on side for the second successive delivery.
And although the Bangladeshi tail added a valuable 67 for the final four wickets with Khaled Mashud carving a cultured 34, the total looks unlikely to deliver the victory needed to stop Australia completing a series win.
Debutant Dan Cullen took his maiden Test wicket with the dismissal of Mashrafe Mortaza while Gillespie, Warne (3-47) and MacGill (3-68) shared the rest.
