England tightened their grip on the Women's Ashes after a seven-wicket victory over Australia in the first one-day international at the MCG and are just one victory away from retaining the trophy.
Under the current format, the women's Ashes features one Test, three one-dayers and three Twenty20s, with the winner decided by the country who accumulates the most points.
A Test match win is worth six points, while two points are on offer for each one-dayer and T20.
England are now 8-0 up in the multi-format series having won the only Test in Perth by 61 runs earlier this month.
Alex Blackwell's unbeaten 82 helped the hosts post 209-3 from their 50 overs.
England slipped to 68-3 in response but an unbroken fourth-wicket stand from Lydia Greenway (69 not out) and Arran Brindle (63 not out) led them home, The BBC reports.
Australia must now win both remaining ODIs and all three Twenty20 internationals to prevent England retaining the trophy.
