Lizelle Lee scored the first century of the WBBL to help the Melbourne Stars get their points tally up and running against the Perth Scorchers at the WACA after four defeats to start the competition. Lee, who also scored the first hundred last season, reached three figures in the final over off 63 balls having started the innings by playing out a maiden from Nicole Bolton. With the next-highest score being 17, Lee had 66% of the total herself. While Meg Lanning was at the crease, fresh off her matchwinning knock the previous night, the Scorchers looked favourites but legspinner Madeline Penna continued her impressive start to the tournament by having Lanning stumped with her third delivery and later added Nat Sciver. With Erin Osborne and Kristen Beams also proving superbly economical the asking rate ballooned out of hand for the middle order.

The Sydney Sixers just about held it together to secure a scrappy four-wicket win against the Melbourne Renegades in Perth as Ellyse Perry's unbeaten 45 helped get them over the line with a ball to spare. It a game littered with some poor decision-making, the Sixers needed 5 off 10 balls with six wickets in hand when Marizanne Kapp and Maddy Darke picked out fielders to bring it down to 2 from 3 before Perry and Lauren Smith found a single apiece. Dane van Niekerk enjoyed a fine all-round match with 30 off 27 balls, which put the chase on course alongside Perry, to follow 2 for 15 off her four overs. Her wickets came as part of a team hat-trick for the Sixers as Courtney Webb was run out before she bowled Tammy Beaumont with an excellent googly then trapped Georgia Wareham sweeping first ball. From 7 for 84, Jess Duffin's unbeaten 34 from 22 balls gave the Renegades a target they came close to defending.

Unbeaten half-centuries from Suzie Bates and Bridget Patterson guided the Adelaide Strikers to an eight-wicket win over the Brisbane Heat in Mackay which took them top of the table. Tahlia McGrath's 26 off 16 balls helped kickstart the chase in the powerplay and it was always under control. The Heat suffered a significant batting collapse as they lost their last seven wickets for 23 runs and failed to bat out the 20 overs. Beth Mooney hit 73 off 49 balls, putting her comfortably at the top of the leading run-scorers at this early stage, and added an opening stand of 56 in six overs with Grace Harris before things started to go wrong.
