State border restrictions and significant scheduling challenges have forced Cricket Australia to postpone the start of the Women's National Cricket League.
The opening seven matches of the 50-over competition, originally scheduled to be played from January 15, have been pushed back more than a month.
The WNCL will now begin in Adelaide on January 25, with South Australia hosting Tasmania at Karen Rolton Oval.
The final remains scheduled for March 27.
"The changes to the WNCL schedule have been made to give us the best possible chance of completing a full season," Cricket Australia head of cricket operations Peter Roach said.
"We'd like to thank the State and Territory associations, players, staff and the ACA for their flexibility and understanding as we navigate the challenges of the pandemic on our summer schedule."
The decision follows last week's announcement that the Australia-India women's one-day series had been postponed.
Originally planned for January, the three-match tour is now likely to be played next summer and also include Twenty20 matches as part of a bumper 2021-22 season.
