Clarke made 101 off 111 balls as Australia recovered from 90 for three to post a challenging 270 for seven before their bowlers restricted Bangladesh to 210 for five in their 50 overs.
The home side started wobbling when they lost their first two wickets for nine runs and could never pose any serious threat to Australia despite opener Tamim Iqbal (62) and captain Shakib Al Hasan (51) each contributing. Former skipper Ricky Ponting made 34.
