Australia 175 for 2 (Sutherland 74*, Perry 65*, Khatun 1-32) beat Bangladesh 172 (Shorna 54, Sharmin 50, Schutt 4-16, Sutherland 2-25, Gardner 2-49) by eight wickets
Megan Schutt struck thrice in the powerplay after Australia asked Bangladesh to bat first for the third game in a row.
Bangladesh found themselves at 18 for 3 in nine overs - the third time in as many matches on tour that they lost three wickets within the first ten overs.
Half-centuries from Shorna Akter and Sharmin Akhter helped Bangladesh huff and puff their way to 172, which Ellyse Perry and Annabel Sutherland knocked off within 23 overs for another one-sided win and a 3-0 series sweep.
Schutt opened the bowling and bowled her ten overs on the go, adding the wicket of Sobhana Mostary, century-maker in the second ODI, to finish with stunning figures of 10-5-16-4. She swung the ball prodigiously and didn't allow Bangladesh to get going at all.
Kim Garth also moved the ball around and was unlucky to end wicketless as she and Schutt bowled unchanged for the first 17 overs. Garth dangled the ball in the right areas and drew the outside edge plenty of times but didn't get anything in the wickets' column.
The ball swung sharply till around the halfway point in Bangladesh's innings, and the batters were often left searching for it. They ended up facing 50 dots in the first ten overs.
As for the early wickets, Murshida Khatun fended an outswinger from Schutt to gully in the third over as Australia mostly went on the fuller side with the new ball; when Schutt changed up to bowl a bouncer, Sarmin Sultana hooked it to fine leg in the seventh over; Schutt then got one to straighten outside off, and Nigar Sultana jabbed it to the wicketkeeper; Schutt struck for the fourth time when Mostary edged an inswinger to gully.
But Sharmin had began to settle after the early wobble. She confidently drove Garth for back-to-back fours to end the 16th over but, with Bangladesh going nowhere at 45 for 4, Sharmin and Shorna decided to play the waiting game.
Both batters enjoyed some luck and bagged the occasional boundary in the middle overs. But the run rate was never too far above three an over.
Sharmin and Shorna's 54-run stand for the fifth wicket - off 98 balls - ended when Sharmin, on 50, slashed Perry to gully in the 34th over. With Ash Gardner striking soon after, it was on Shorna to take Bangladesh to a respectable total.
Garth, meanwhile, endured more bad luck. Apart from the edges that hadn't gone to hand, an edge from Mostary in the 12th over had gone through the hands of gully, and now, in the 44th over, she thought she had her first wicket when she trapped Shorna, on 42 at the time, in front, only for the decision to be overturned on review. Next ball, Shorna guided one for four between short third and point to pile on the frustration.
Shorna reached her fifty in the 47th over, and fell for 54 courtesy agile work by wicketkeeper Beth Mooney in the 49th. Despite Mooney standing up to the stumps, Sutherland bowled a bouncer. Shorna looked to hook but missed, and Mooney, collecting the ball with a reverse cup, whipped the bails off as Shorna's back leg dragged out of the crease.
A chase of 173 was rarely going to be challenging for an Australia side that had cantered to targets of 167 and 221 earlier in the series. Bangladesh, though, checked a quick start. Sultana Khatun trapped Georgia Voll for 11 in the second over, while debutant seamer Disha Biswas bowled Mooney on 21 in the sixth.
But if, at 38 for 2, Bangladesh had dreamt of a miracle, then Sutherland and Perry quickly binned those thoughts. Perry and Sutherland combined to slam seven boundaries in the next five overs, as Australia counter-attacked to finish the powerplay at 74 for 2 to all but seal the deal.
Both batters sped away towards the target, and seemed in a race to reach their half-centuries. Sutherland got there first when she launched Biswas over mid-off by advancing down the track on the fourth ball of the 20th over. The shot underscored her dominance. Two balls later, Perry jogged a single to also get to the landmark.
From 140 for 2 in 20 overs, the pair knocked off the remaining 33 runs off the next 16 balls as the boundaries kept flowing. Sutherland smashed 12 of them in her 74*, while Perry hit eight in her 65*.
After the game ended, some Bangladesh players had their fangirl moments when they clicked photos with their counterparts. Apart from the valuable experience on the field, they will take back some happy memories from off it.
