Mitchell Starc delivered a lethal opening spell of swing bowling to skittle Bangladesh for just 64 before Bangladesh’s pacers hit back to reduce Australia to 50/3 by tea on Day 1 at Mackay. Starc's Six-Wicket Blitz: Mitchell Starc took a 22-ball five-wicket haul, starting by dismissing Shadman Islam off the first ball of the match. He finished with remarkable figures of 6 for 12 in 10 overs, pushing his career tally past Dale Steyn (439 wickets). Bangladesh Collapse Early: Bangladesh slid to 12/5—their lowest score at five wickets down in Test history—and were bowled out for 64 in 34 overs. No. 11 Shoriful Islam top-scored with 14 as the last five wickets added 47 runs. Fast Bowlers Lead Fightback: Bangladesh's seamers responded aggressively after lunch. Taskin Ahmed had returning opener Matt Renshaw caught in the slips for 8, while Shoriful Islam bowled both Travis Head (chopping on) and Marnus Labuschagne (around his legs). Tea Status: Australia went to tea at 50/3 in 11 overs, trailing Bangladesh's first-innings score by 14 runs with Steven Smith and Cameron Green at the crease. Mushfiqur lasted 41 balls before a Cummins delivery burst through his bat and pad, but Mehidy Hasan Miraz and Hasan Mahmud managed to prevent any further damage in the first session, which ended with Bangladesh at 35 for 6. Cummins got Mehidy driving away from his body shortly after lunch, with Webster taking a diving catch to his right. At No. 7, Mehidy became the first batter in this innings to reach double digits. Josh Hazlewood opened his account when Mahmud flicked him to leg gully after surviving 35 balls, before Cummins removed Taskin Ahmed, who skied the ball to Matt Renshaw at square leg. Three fours towards the end from Shoriful and Taijul Islam took Bangladesh past 43, their lowest total in Tests. Starc finished things up with Shoriful's wicket, caught behind.
