England captain Heather Knight has said her side were "really unlucky" after Australia retained the Women's Ashes with a 27-run victory in the first one-day international.
The victory saw Australia take an 8-4 lead in the multi-format series with two ODIs left to play, as England were bowled out for 178 as they chased a below-par 206.
Beth Mooney was the standout batter for Australia, scoring 73, while Katherine Brunt and Kate Cross both picked up three wickets each.
