A 204-run stand between Ellyse Perry and Meg Lanning secured the Southern Stars the ODI Series with an eight-wicket win over the West Indies in the third ODI at Bowral.
The win has also fortified the Australian side's position at the top of the points table of the ICC Women's Championship.
After winning the toss and electing to bat first the West Indies put on 7-220 from their 50 overs, which the Commonwealth Bank Southern Stars chased down in the 44th over, finishing 2-222.
Lanning's unbeaten knock of 135* from 127 balls earned her the player-of-the-match award. The total was Lanning's highest ever in ODI cricket and it was her fifth ODI century, which moves her to equal second alongside Belinda Clark on the list of most ODI centuries for Australian women, three behind Karen Rolton (8). She also become the first female to score a century on Bradman Oval.
The West Indies opening pair of Hayley Matthews (60) and Kycia Knight (40) put on a 97-run partnership before Knight was trapped leg-before-wicket by Erin Osborne (2-51) in the 20th over.
Matthews, who only made her ODI debut in the first match at Hurstville Oval, notched up her third consecutive half-century, taking her total runs for the series to 204.
Shemaine Campbelle was assisted from the field after the 39th over and retired not out on 12* and took not further part in the match, after which West Indies Captain Merissa
Aguilleira (30) and Shaquana Quintyne (33*) put together an important 61-run partnership.
Rene Farrell (2-40) was the other multiple wicket-taker for the Stars, while Ellyse Perry returned economical figures of 1-27 from her 10 overs.
After losing openers Nicole Bolton (9) and Elyse Villani (5) in the first five overs, Lanning (135*) and Perry (64*) came together at the crease and put on a 204-run partnership, which was the fourth highest Australian women's ODI partnership.
It was also Perry's third consecutive half century and pushed her total runs for the ODI series move to 189.
Lanning's knock included 22 fours and she is now the leading run scorer of the ODI series thus far, with a total of 252.
Stafanie Taylor (1-32) and Deandra Dottin (1-45) were the only West Indies bowlers to pick up wickets.
The two teams will meet for the final ODI of the series at Bradman Oval in Bowral on Tuesday.
