BRISBANE - A career-best 47 not out from Erin Osborne and her 41-run partnership with Delissa Kimmince led Australia Women to a score of 9 for 220 before their bowlers dismissed Pakistan Women for 183 to seal a 4-0 series win.

Nicole Bolton and Alyssa Healy had given Australia a good start after Meg Lanning won the toss and opted to bat. The pair added 52 for the first wicket but Sana Mir dismissed both of them in successive overs and Lanning's wicket, in the 18th over, left Australia wobbling at 3 for 66.

Alex Blackwell and Jess Jonassen also failed to build a substantial partnership and were dismissed by the 34th over, falling to fast bowlers Qanita Jalil and Maham Tariq. The sixth-wicket partnership between Kimmince and Osborne revived the momentum of the innings and helped Australia draw closer to 200. The pair managed a healthy run-rate of 5.46 during the partnership, given that neither batsman scored a boundary during their respective innings. After Kimmince fell for 42 off 53 balls, Osborne continued shepherding the lower order, eventually finishing on an unbeaten 47 off 51 balls.

Megan Schutt, who returned to the side after missing the third ODI, gave Australia an early breakthrough, dismissing Pakistan opener Marina Iqbal for 3 in the fourth over.

Her wicket brought Bismah Maroof and Javeria Khan together at the crease and the pair, Pakistan's most successful batsmen in this series, stitched together a solid 79-run stand. Javeria also scored her first fifty of the series, hitting six fours in her 84-ball 54. Osborne provided the wickets for Australia, as her off spin claimed both Maroof and Javeria in the space of six runs to leave Pakistan shaky at 3 for 95. The rest of the Australian bowling choked off the runs and kept chipping away at the wickets, before Pakistan's innings ended in last over.

BRIEF SCORE: Australia Women 9 for 220 (Osborne 47*, Kimmince 42, Mir 3-44) beat Pakistan Women 183 (Javeria 54, Coyte 3-32) by 37 runs.
