Alex Blackwell steered Australia to a seven-wicket win over England in the women's quadrangular one-day international series.
Blackwell finished unbeaten on 54 as the tourists overhauled a target of 169 with 15 overs to spare at Lord's.
The tone of the run chase was set by teenage opener Meg Lanning, who blasted nine fours in her 43 in 33 balls.
Lanning fell to left-arm spinner Holly Colvin (1-39) in the 11th over and England were back in the game when off-spinner Danielle Wyatt (1-20) had Leah Poulton caught behind three overs later for a seven-ball duck.
But, from 59-2, Shelley Nitschke (53) and Blackwell constructed a 94-run stand for the third wicket to take Australia to the brink of victory.
Nitschke was run out with 16 still required but Jess Cameron (10no) joined Blackwell to finish the job.
Earlier, England had been bowled out for 168 in 48 overs after choosing to bat first.
Australia's new-ball pair Clea Smith (2-22) and Sarah Coyte (2-31) did the early damage as England - world champions in the 50-over format - were reduced to 26-4.
Lydia Greenway (34), Arran Brindle (22) and Colvin (29) scripted a recovery of sorts but spinner Lisa Sthalekar picked up 3-30 to ensure a below-par final total.
The final group match was a dress rehearsal for Thursday's quadrangular series final at Wormsley between the same sides.
