A record-breaking second-wicket stand between centurion Shahriar Nafees and captain Habibul Bashar has handed Bangladesh a dream start in the first Test in Fatullah.
Nafees and Bashar shared a boundary-laden 187-run partnership - Bangladesh's highest stand against any nation in its Test history - to lay the platform for an imposing score of 5-355 at stumps on day one.
At the close, Rajin Saleh was unbeaten on 35 with Khaled Mashud on two not out.
After wisely electing to bat first on a lifeless wicket, the top order Bangladeshi batsmen made light work of piling on the runs against a tired-looking Australian attack.
The second-wicket pair's mammoth total - surpassing the previous best stand of 167 between Bashar and Javed Omar against Pakistan in 2003 - came to an end the delivery before tea when Bashar threw his wicket away, looping a Stuart MacGill long hop to Brett Lee at mid-on for 76.
Nafees continued into the evening session before MacGill struck again with a fuller delivery which bowled the 20-year-old opener around his legs as he attempted to sweep.
His impressive 138 - his maiden first-class century - included 19 boundaries and lies third on the all-time list of Bangladeshi individual Test scores behind Mohammad Ashraful's 158 not out against India in 2004-05.
Nafees will also be remembered for becoming the first Bangladeshi Test batsman to pass three figures against the world champions.
During the marathon stand, both Nafees and Bashar took a liking to Shane Warne, who endured a miserable day in the field.
Adam Gilchrist dropped Bashar off Warne's bowling just before lunch much to the dismay of the champion leg-spinner, then Warne failed to hold a sharp chance off Jason Gillespie with Nafees on 66.
He finished day one with figures of 20 overs for 112 runs before an elbow injury ruled him out of bowling for the rest of the day.
Fellow leg-spinner MacGill (3-82) faired much better despite Gilchrist dropping Saleh late, while Gillespie returned a respectable 2-36 in his international recall - including Ashraful's dismissal immediately after drinks in the final session for 29.
The final wicket of Aftab Ahmed (29) gave the score a better look for the tourists after Bangladesh had rattled along at close-on six runs per over before lunch, accumulating an incredible 24 boundaries in the 25-over morning session for the loss of just one wicket.
That fell in Gillespie's first over when the South Australian paceman had Omar trapped in front of the stumps on 27.
Gillespie, replacing a below-par Stuart Clark after an expensive six-over spell for 34 runs, jagged a wicked delivery back into the opener's pads after a first-wicket stand of 51 with Nafees.
