Australia Women ended England Women's unbeaten run with a comprehensive seven-wicket victory at Lord's to lay down a marker ahead of the two side's repeat meeting in the final at Wormsley.

England's batting, up until now a huge strength, was undone as they were dismissed for 168 and half-centuries from Alex Blackwell and Shelley Nitschke saw Australia past their target with 15 overs to spare.

Off-spinner Lisa Sthalekar returned three for 30 while Clea Smith and Sarah Coyte both took two wickets as England were dismissed in 48 overs.

They never fully recovered from being reduced to 26 for four early on and despite Lydia Greenway (34) and Holly Colvin (29) fighting back, their score looked inadequate.

By contrast, Australia started strongly and didn't look back with Nitschke (53) and Meg Lanning (43) putting on 54 for the opening wicket.

England struck to having Lanning caught by Arran Brindle off Colvin and then Leah Poulton caught by Sarah Taylor off Danielle Wyatt for nought but Australia rebuilt again.

Blackwell stroked an unbeaten 54 before Nitschke - in her penultimate match before retirement - was run out by Greenway, leaving Blackwell and Jess Cameron (10 not out) to ease Australia to victory.
