On Tuesday, October 20, in the second Twenty20 International at North Sydney Oval, Australia defeated New Zealand by 40 runs thanks to Ashleigh Gardner's star turn with the bat and the ball. Australia secured the Rose Bowl in its first match as a T20I series with the victory, giving them an unbreakable 2-0 series lead. Gardner struck 84 off 45 balls to lift Australia to 167 after they had been reduced to 41 for 3 in the seventh over. She then returned 2 for 17 with the ball while Georgia Wareham claimed 3 for 18 as New Zealand were restricted to 127 on a tough wicket. Australia's innings had an uncertain start after New Zealand opted to bowl. Georgia Voll failed to score, and Ellyse Perry and Phoebe Litchfield, who came in for Tahlia McGrath, also left quickly, putting pressure on the hosts. Beth Mooney, who made 39 off 28 balls, helped lead a counter-attack alongside Gardner with the pair adding 60 for the fourth wicket in just 35 balls. From there, Gardner took charge. She built a crucial partnership with Mooney before continuing to score freely after the opener's dismissal. Reaching her half-century off just 29 deliveries, Gardner tore into the attack in the death overs, with the most damaging assault coming in the penultimate over. In a four-ball sequence, Gardner struck Jess Kerr for two fours and two sixes, giving Australia a significant late boost. She was run out on the last pitch of the inning, but her 10 fours and 4 sixes helped the hosts reach a respectable total. The pursuit by New Zealand never gained sufficient momentum. They had Australia in trouble early in the first innings but struggled to replicate that control with the bat. The visitors were 56/2 at the halfway stage, with the required rate climbing steadily. After that, Wareham decisively swayed the contest in Australia's favor. The leg-spinner finished with 3 for 18 from four overs and was involved in several key moments in the field, adding two catches and a run-out to her wickets. Amelia Kerr top-scored for New Zealand with 32, but her innings came off 38 deliveries and was well off the pace in the face of a mounting asking rate. In the end, the visitors were 40 runs behind.
