Alyssa Healy made history by producing one of the greatest ODI innings as Australia beat England by 71 runs to win the Women's Cricket World Cup for a seventh time.

Healy crafted a magnificent 170 – a record score by a woman or man in a World Cup final – as Australia racked up a mammoth 356-5 after Heather Knight won the toss and opted to field at Hagley Oval on Sunday.

The wicketkeeper-batter struck 26 boundaries in an outstanding 138-ball knock, becoming the first player to score a century in both the semi-final and final at the same World Cup.

Healy's masterclass also ensured she set a record for the most runs scored by a woman in a World Cup, taking her tally to an astonishing 509 in Christchurch.

Rachael Haynes (68) and Healy got Australia off to a dream start with an opening stand of 160 before number three Beth Mooney made 62 off only 47 balls.

Healy's epic knock was finally ended by Anya Shrubsole (3-46) in the 46th over, the centurion stumped by Amy Jones.

Defending champions England faced a massive run chase and Nat Sciver ensured they might make a good fight of it, scoring a brilliant unbeaten 148.

Sciver was left stranded, though, as opener Tammy Beaumont was the second-highest scorer with only 27.

Alana King (3-64), Jess Jonassen (3-57) and Megan Schutt (2-42) did the bulk of the damage as Australia regained the title.
