Shakib, Rahim propel Bangladesh to 153-5
Bangladeshi batsman Shakib Al Hasan plays a shot during the ICC World Twenty20 tournament Group 2 match between Australia and Bangladesh at the Sher-e-Bangla stadium in Dhaka on April 1, 2014 - by Munir Uz Zaman
Shakib scored a 52-ball 66 for his fourth Twenty20 fifty -- the first from any Bangladeshi batsman in the tournament -- and added 112 for the third wicket with skipper Mushfiqur Rahim (47) after the home team won the toss and opted to bat at Shere Bangla stadium.
The duo created a new Bangladesh record for the third wicket in all Twenty20 internationals, beating the 109-run stand set by Aftab Ahmed and Mohammad Ashraful against the West Indies at Johannesburg in the 2007 World Twenty20.
Both Australia and Bangladesh are playing for pride after being already knocked out of the semi-finals.
Bangladesh lost openers Anamul Haque (nought) and Tamim Iqbal (five) in paceman Nathan Coulter-Nile's first two overs, leaving the repair work to the two most senior players of the team.
Coulter-Nile was the pick of Australian bowlers with 2-17.
Shakib hit five boundaries and three sixes before he fell to a brilliant catch by Glenn Maxwell off Doug Bollinger.
Rahim matched his illustrious partner as he smashed five boundaries and a six off just 36 balls, before he holed out off Shane Watson in the 17th over.
India have already qualified for the semi-finals from this group while Pakistan and the West Indies meet in the last match later Tuesday to decide the second semi-final spot.
South Africa, who meet India in the second semi-final on Friday, and Sri Lanka have advanced to the last four from Group one.
