Alyssa Healy, who scored a 52-ball century, and Ellyse Perry rewrote the record books at the WACA with an unbroken opening stand of 199 in what became a 45-run victory for the Sydney Sixers against the Melbourne Stars. It was the highest stand for any wicket in the WBBL comfortably surpassing the previous best of 156. Healy began the final over on 89 and regained the strike with three balls left, sending them all to the boundary to finish on 106 - her third century in a month after T20I and ODI tons against Sri Lanka. Perry, meanwhile, marked her 29th birthday with 87 off 68 balls and she is now averaging 139.50 this season. Lizelle Lee, who made a century the previous day, gave the chase a rapid start with 25 off 17 balls but after she fell to Ash Gardner the Stars didn't threaten. Captain Elyse Villani top-scored with 59.

The Sydney Thunder returned to the top of the table with a well-crafted six-wicket victory the Hobart Hurricanes in Burnie. Rachel Priest gave the chase of 149 momentum with 50 off 34 balls and though the Thunder were 3 for 81 when she fell the required rate was in hand. Alex Blackwell and Phoebe Litchfield again joined forces with Litchfield unbeaten on 26 when the win came with 11 balls to spare. The chase was aided by 21 wides from the Hurricanes attack. Their innings had come to life in the final 10 overs which brought 108 runs after they reached halfway on just 2 for 40. Heather Knight hit an unbeaten 77 off 49 balls while Chloe Tryon again showed her hitting power with 21 off 12. Pakistan allrounder Nida Dar took 2 for 16 off four overs.

Beth Mooney's prolific WBBL continued as her unbeaten 77 off 51 eased the Brisbane Heat to a commanding nine-wicket win over the Adelaide Strikers following their batting collapse the previous day. Mooney, who is comfortably the leading run-scorer so far this season, added 65 for the first wicket with Grace Harris then completed the job alongside Jess Jonassen with the Heat having 17 balls to spare. Georgia Prestwidge had played a key role with the ball to finish with 3 for 29, two of those wickets - removing Bridget Patterson and Lauren Winfield - helping reduce the Strikers to 5 for 75 in the 13th over. Sophie Devine (65) held the innings together but the total proved well short of challenging the Heat.
