The victory is worth six points to England in the three-format series, meaning two wins out of the six limited overs matches – three 50-over and three Twenty20 – and they retain the Ashes after winning them in England last year.
Australia were struggling on the final day on 5-57 chasing 185 for victory. Perry backed up her first innings 71 with a spirited series of boundaries taking the score to 99 but when she went for 31 it was always going to be an uphill battle.
Anya Shrubsole, who took four wickets in the first innings, took the dual sport international’s wicket and finished with 3-48 as she finished off the tail to secure the win.
Perry was also Australia’s best with the ball taking 4-41 in the first innings and 5-38 in the second to win player of the match in the losing side.
The first of the ODIs will be played on Sunday in Melbourne.
