Australia suffered a stunning 86-run defeat to Bangladesh in Mirpur, marking only their second one-day international loss to the nation and ending a 21-year unbeaten streak against them. The visitors, missing several first-team players, dropped six catches that allowed Mosaddek Hossain to rescue Bangladesh with 86 runs. The hosts posted 284-8 in a performance that exposed Australia's weakened squad.

Australia's chase collapsed early as they lost Matt Short to the first ball and Marnus Labuschagne, slumping to 2-2. Stand-in captain Josh Inglis joined a long list of dismissals as Bangladesh's bowlers dominated. Left-arm pacer Nahid Rana proved instrumental with 4-41, while spinner Mosaddek contributed 2-37 in his first appearance in four years to help restrict Australia to 191-9.

A premature end to play due to storms sealed Bangladesh's historic victory under the Duckworth-Lewis-Stern method. This result sends a clear message about Bangladesh's progress in limited-overs cricket while highlighting Australia's vulnerability when missing key players. The comprehensive defeat raises serious questions about the tourists' preparation and squad selection for the remainder of the series.
