Mackay witnessed a thrilling second T20I as Australia triumphed over New Zealand by 29 runs, securing the series victory despite a dramatic batting collapse. After winning the toss and opting to bat first, Australia set a total of 142 runs but was rocked by a stunning collapse, losing 7 wickets for only 28 runs and ultimately getting bowled out in 19.5 overs. The highlight of the match was New Zealand's Amelia Kerr, who delivered an exceptional performance, claiming 4 wickets for just 20 runs by exploiting weaknesses in the Australian batting lineup.
Alyssa Healy was the standout performer for Australia, scoring 38 runs off 25 balls, with Ellyse Perry contributing a cautious 34 runs. However, Perry’s unusual run-out—she misjudged a deflected ball and set off for a run—proved to be a pivotal moment, leading to a swift decline in the team’s performance. Following her exit, Australia’s middle and lower order crumbled under Kerr's spell, resulting in significant damage to the batting lineup.
Chasing a target of 143 runs, New Zealand's innings began steadily, but the Australian bowlers kept them in check, led by tight spells from Ashleigh Gardner and Annabel Sutherland, who took crucial wickets and restricted New Zealand's runs. Although Suzie Bates made a solid start with 34 runs, the pressure built as New Zealand's top order fell to the Australian bowling attack.
