England women levelled the Ashes series with a 51-run victory in the second One Day International at Hove.
Captain Charlotte Edwards top-scored with 53 as England posted 253-6 in their 50 overs and the tourists never looked likely to reach their target, despite a battling innings of 81 from Jessica Cameron.
Edwards and Heather Knight (31) got England off to a pacy start but the run-scoring slowed until the power play in the middle of the innings which saw Lydia Greenway (46) and Arran Brindle, with 42 from 46 deliveries, cut loose to take the initiative.
Natalie Sciver also weighed in with a crucial 26 from 20 balls.
The Australians could not have made a worse start in their run chase with both openers, Rachael Haynes and Meghann Lanning, failing to score.
The Aussies were reeling at two wickets down for two runs but were steadied by 24-year-old Cameron and Alexandra Blackwell.
The breakthrough came courtesy of a brilliant caught and bowled by Jenny Gunn to dismiss Blackwell for 23 and a wonderful piece of fielding by Greenway, backed up by athletic wicket-keeping from Sarah Taylor, which saw Ellyse Perry run out for five.
Cameron stayed around as the asking rate steadily increased but when she was emphatically bowled by the impressive Katherine Brunt, having scored her 81 from 107 balls, the Australian challenge was effectively over and eventually they were bowled out for 205 from 48.2 overs.
With one more one-day international and three Twenty20 games remaining, the sides are level on four points each in the new women's Ashes points system which collates one Test, three one-dayers and three Twenty20 games.
After a drawn Test, Australia had gone ahead with a 27-run win in last Sunday's opening 50-over match at Lord's.
But this win gives England vital momentum for Sunday's third one-day international, again at Hove. Victory there would put England in a dominant position with three Twenty20s in five days to come next week.
