Batting first, Australia posted 7-269 thanks largely to Alyssa Healy (68) and Meg Lanning (69) who both posted half-centuries.  

However, it was with the ball that Australia showed just how dangerous they are dismissing England with ease. 

Fast-bowler Ellyse Perry took an ODI career best and Australian record 7-22 from ten overs, and Megan Schutt (2-21).

Laura Marsh toiled hard for England but it was to no avail as Australia dismissed the home side for 75. 

Perry's record came almost four years to the day after she bagged six wickets to bowl Australia to a Test match victory. 

However, the 28-year-old has downplayed her performance at Canterbury.

"I honestly think today just went my way, which is nice, but across the series there has been some great performances and for us to start the way that we have, and be six points clear, is the absolute dream start so all of us are really chuffed and myself especially," she said.

Undefeated so far this Ashes, it gives Australia a six-point lead with a Test and three Twenty20 Internationals to follow.
