The Southern Stars as the Aussie women team are known in the cricketing circuit, have been on a roll since winning the second edition of the Women's World Twenty20 in 2010.
The Meg Lanning led Australian women's side choked arch-rivals England's 133-run chase with a five-run victory in the semifinal. Lanning has been their leading run-getter with 149 runs and against England her 50-ball 55 on a slow Kotla deck was the cornerstone to their winning total of 132/6.
They were provided a strong start from the openers Alyssa Healy and Elyse Villani with a 41-run stand, their highest of the tournament.
Under criticism for over dependence on Lanning, Alyssa took the attack to the English pace spearhead Katherine Brunt, that really set the tone as they could muster a fine Powerplay performance.
