Alyssa Healy produced a record-breaking 170 to guide Australia to their seventh Women's Cricket World Cup but she still believes she is not a "big-game player".

Healy registered the highest score – by a man or woman – in a World Cup final in a superb 138-ball knock, becoming the first player to score a century in both the semi-final and final at the same World Cup.

The wicketkeeper-batter's scintillating outing also ensured she set a record for the most runs scored by a woman in the tournament, taking her tally to an astonishing 509 in Christchurch, as Australia defeated England by 71 runs on Sunday.

But the 32-year-old opener does not think she can be labelled as a player for the big occasions despite her heroics.

"Not sure I'll let you name it. I'll let you find it," Healy told reporters after the final. "But, 'brave'? I just think you've got to be brave to come out in situations like that to be able to play your game.

"You know that the opposition are going to come really hard at you. They want to take your wicket early and you have got to be brave and back your skills.

"So, personally, I'm really proud of that. I still don't think I'm a big-game player. So, turn that down, but you have just got to be brave to be able to do it."

Healy became the first player – man or woman – to hit 150 or more in the final of a world tournament, and she acknowledged that the victory means even more after failing to make the World Cup final in 2017.

"I don't think I've ever dreamt of anything like that before, I can guarantee you that," she added.

"But I'm just really proud to have been able to contribute to this win. I messaged Pez [Ellyse Perry] this morning when I found out she was in the XI and I said, like, 'I just want to be a part of it. I really want this. I want to contribute to this win and to be able to do that was really special.

"I ran drinks the whole 2013 World Cup. You know we didn't make the final in 2017. So, for me, this trophy means a lot and to be able to turn up at the back end and go all right in the last two games means a whole heap."

The records continued to tumble for Healy, whose 170 also surpassed Adam Gilchrist's 149 in 2007 as the highest score in a World Cup final by an Australian wicketkeeper-batter, but she remains uninterested in those achievements.

"That's pretty cool, [but] I'm not in the game for that sort of stuff. Getting our team into a winning position was the most important thing," she responded on Gilchrist's record.

"I guess one day when I retire and I reflect on my career, it's a moment that I can kind of remember and cherish that. I always looked up to Adam Gilchrist; Uncle Ian [Healy] first, but then Adam Gilchrist, so to knock him off the pedestal - sorry about that - but I'm sure he'll appreciate it."
