Australia 138 for 2 (Mooney 75*, Voll 50) beat New Zealand 137 for 2 (A Kerr 51*, Devine 39*, Brown 1-22) by eight wickets
But their unbeaten 90-run stand off 76 balls proved too slow as Australia’s opening pair set a slew of records with a staggering display of sustained boundary hitting with Mooney finishing with 75 not out from just 42 balls while Voll made 51 off 30.
They posted 77 in the powerplay, which was the most Australia’s women have ever produced in a T20I. They brought up their century stand in 8.2 overs and posted the highest opening partnership, 123, by an Australian female pair against New Zealand in a T20I.
Mooney celebrated her 200th international for Australia across all formats by racing to her 26th half-century in T20Is from 28 balls, to go with her two centuries. Voll cruised to her maiden T20I half-century in 30 balls but played second fiddle as Mooney accelerated past her by facing more of the strike.
Mooney was brutal going both off side and leg side with trademark lofted cover drives mixed with pick-ups over midwicket. Voll was savage on anything straight, mowing it repeatedly over the leg side with her powerful bottom hand until she finally picked out deep square off Lea Tahuhu with just 15 runs to win.
New Zealand’s total was always well under par after winning the toss and batting first. Australia’s attack, which did not feature Ashes star Alana King who was left out of the line-up, was frugal throughout. They could have restricted New Zealand even further had they not dropped two catches and missed three clear-cut run out chances.
Devine, playing her first game since January after taking a mental health break, showed clear signs of rust as she battled for fluency. She was 16 off 27 at one point as all of Australia’s bowlers tied her down. Annabel Sutherland was particularly tough to get away in the middle overs, conceding just 21 off her four.
Gardner’s dropped catch seemed to spark Devine. Gardner left in clear pain with blood flowing from a cut on her right index finger and was unable to complete her third over due to the power of Devine’s strike. She found the boundary four more times after that, having scored just one across her first 27 deliveries.
Kerr was more consistent across her innings but only found the rope five times in her fourth T20I half-century. New Zealand scored just 17 boundaries in total with Kerr and Devine striking five each. Mooney struck ten fours herself, plus a six, while Voll crunched nine boundaries.
Australia claim a 1-0 series lead, with matches to come at Mount Maunganui on Sunday and Wellington on Wednesday.
