Australia have recalled left-handed batsman Usman Khawaja and left-arm spinner Ashton Agar, both of whom toured India earlier this year but did not play in the four-test series.
Bangladesh left out paceman Taskin Ahmed and opted for two seamers and a three-pronged spin attack, which includes off-spinner Mehedy Hasan and left-arm spinner Taijul Islam.
"We are very confident after beating Sri Lanka in Colombo and we also beat England here last year. I hope the boys are fired up," Mushfiqur said.
The match marks the 50th test match for Bangladesh opener Tamim Iqbal and spin-bowling all-rounder Shakib Al Hasan.
Smith admitted that Australia would also have batted had he won the toss.
"The wicket looks pretty slow," he said.
Teams:
Bangladesh: Tamim Iqbal, Soumya Sarkar, Imrul Kayes, Sabbir Rahman, Mushfiqur Rahim (captain-wicketkeeper), Shakib Al Hasan, Nasir Hossain, Mehidy Hasan, Taijul Islam, Shafiul Islam, Mustafizur Rahman.
Australia: David Warner, Matt Renshaw, Usman Khawaja, Steven Smith (captain), Peter Handscomb, Glenn Maxwell, Matthew Wade (wicketkeeper), Ashton Agar, Pat Cummins, Josh Hazlewood, Nathan Lyon.
