Next year's women's Ashes series in Australia will work to the same format as the current series in England, it has been confirmed.
England's women take on their rivals across different formats of the game, with points allocated throughout the seven matches.
The sides will contest one Test match, starting in Perth on January 10, with three one-day internationals and three Twenty20 matches to follow.
Six points will be awarded to the winning side in the Test match, with two points apiece if it is drawn.
Winners of the shorter-format matches will earn two points, with a point each if the ODI's are drawn and a one-over eliminator in the event of a tied T20 clash.
The points system was introduced for the current series and has proved successful.
England lead the ongoing series 6-4 with the three T20's remaining, having drawn the Test and won two of the ODI's.
The T20 matches take place at Chelmsford on Tuesday and the Rose Bowl on Thursday, with Saturday's encounter at Chester-le-Street rounding off the series.
