Healy’s 148 not out from just 61 balls against Sri Lanka, at North Sydney Oval, took her 2019 T20 International tally to 372 runs at the excellent average of 53.14 and remarkable strike rate of 173.
It was her first T20 International century coming just two days after she celebrated her 100th appearance at that level. Australia made a huge 2/226 from its 20 overs winning by 132 runs to clean sweep the three-match series.
Healy’s performances this year have only built on what was achieved during 2018 which saw her named the ICC Women’s T20 International Player of the Year.
The 29-year-old made 578 runs last year at 41.3 claiming 10 catches and 13 stumpings.
Since September 2018, Healy has received four Player of the Series awards at the Twenty20 International level including best player at the Women’s World T20 won by Australia in November.
Healy scored 225 runs at 56.25 during the tournament, completing four catches and four stumpings.
Such form with the bat was replicated during the Women’s Big Bash last season, scoring 445 runs at the immense strike rate of 141.71 including 112 not out from 69 balls against the Adelaide Strikers, her highest WBBL score.
Healy also received her first Belinda Clark Award in February recognising her as the most outstanding Australian Female cricketer across the preceding 12 months.
Her world record innings on Wednesday exhibited the pure ball striking which has been such a feature of her batting in recent times.
All but 30 of her 148 runs came in fours and sixes. She reached the boundary an incredible 19 times and cleared it on seven occasions.
Healy broke the record just two months after Australian captain Meg Lanning set the record during the Women’s Ashes in July.
Lanning was at the crease when Healy passed her mark of 133 not out.
“There was a bit of banter. I said I’m coming for you Meg at some point when it came up on the big screen,” Healy said with a smile after the match on Wednesday.
“Things came off alright today and I’m pretty pleased with that.
“I didn’t change my mind set at all coming into this series. I was going to go out there and try and get the team off to a good start.
"Some days it comes off and some days it doesn’t.
“I feel like I did my job in the first two games but just couldn’t quite capitalise on the start.
“I guess today was extra special, it’s just one of those days where everything seems to come off alright.”
The Australian Women’s team now head to Brisbane for three One-Day Internationals against the Sri Lankans before Healy, Sixers captain Ellyse Perry and allrounder Ashleigh Gardner return to Sydney to prepare for the start of the WBBL on 18 October.
The Sixers start their campaign against cross-town rivals the Sydney Thunder at North Sydney Oval and Sixers fans will be hoping Healy can channel her world record when she returns in magenta.
