The group winners at the end of the 56-game regular season will progress straight to the final with an Eliminator and a Challenger replacing the semi-finals
The Women's Big Bash League will see a revised knock-out format for its seventh edition scheduled to start next month.
A place in the final is now up for grabs for the team that finishes top of the group following the 56-game regular season.
Sides ranked third and fourth will face-off in The Eliminator with the winner taking on the second-place side from the group for a place in the final.
The WBBL is due to kick-off in Sydney on October 14, however Covid-19 travel rules may still affect the fixture list.
Currently, movement out of New South Wales and Victoria is restricted. India's tour of Australia, which starts on September 19, has already been shifted entirely to Queensland as a result.
