The Southern Stars beat the West Indies by 114 runs in Mumbai on Sunday to lift the ICC Women's World Cup trophy for a sixth time.
Led by a hampered Ellyse Perry, the Australians never looked like losing the tournament decider, after making 7-259 and then restricting the West Indies to just 145.
Player-of-the-match Jess Cameron guided the Australian innings, smashing 75 off 76 balls to carry the team from 1-52 to 4-181.
Opener Rachael Haynes also made a half-century, crunching 52 from 74 deliveries and combining for a 64-run partnership with Cameron.
Cameos from captain Jodie Fields (36 off 38) and Perry (25 off 22) boosted the Stars' total, and erased the momentum the West Indies had built after their run of four wickets in eight overs.
The Windies got off to a slow start to their chase, with Australian pace bowler Megan Schutt grabbing maidens in the first and third overs.
Natasha McLean and Kycia Knight eventually got going and put on 32 before Perry struck in a dramatic 10th over.
The dual Australian international of football and cricket looked to break down with a left ankle injury when she attempted to run in and bowl her first delivery.
Twice Perry reached the crease but couldn't bowl in a worrying sign for, however those concerns were waved away when the 22-year-old finished the over with Australia's first wicket.
Perry (3-19) trapped Knight lbw for 17, and then followed up with her second over also producing a wicket and equal parts controversy.
She thought she had dismissed Stafanie Taylor when the Windies number three nicked one to Meg Lanning at first slip.
However, despite Lanning's confidence of claiming the low catch and TV replays seemingly backing up her claims, third umpire Ruchira Palliyaguruge turned down the appeal after a lengthy delay.
Not to be denied, Perry got rid of Taylor three balls later anyway - completing a regulation caught-and-bowled dismissal.
McLean was next to depart, when she played across the line and was also lbw to Perry for 13.
Luck was not going the way of the Caribbean side as Kyshona Knight was forced to retire hurt in the 22nd over.
The Australians marched on in style, spinner Lisa Sthalekar nabbing a wicket with her first ball to see off danger woman Merissa Aguilleira for 23 when she spun through a wide gap between bat and pad to hit the top of off stump.
Deandra Dottin went the same way as Aguilleira, as Sthalekar finished with 2-20 off her 10 overs.
Megan Schutt ensured she finished the tournament as the leading wicket-taker with 15, taking the outright lead with the dismissal of Shemaine Campbelle for 11, before grabbing another to finish with 2-38.
Erin Osborne (2-26) got in on the act late, before Julie Hunter clinched the final wicket as the Stars celebrated winning the World Cup for the second time in three tournaments since 2005.
