Pakistan 143 for 2 (Ayub 42, Shafique 37, Morris 2-24) beat Australia 140 (Abbott 30, Afridi 3-32, Naseem 3-54, Rauf 2-24) by eight wickets

Completing a remarkable revival, having been engulfed in turmoil ahead of the tour, Pakistan claimed a rare series triumph in Australia after a comprehensive eight-wicket victory on a bouncy Optus Stadium surface in the third and final ODI.

Having lost a heartbreaker in the opener at the MCG, Pakistan rebounded brilliantly with almost flawless performances in Adelaide and Perth to completely overwhelm world champions Australia, who have plenty of question marks ahead of the upcoming Champions Trophy 2025.

It was Pakistan's first series victory in Australia since 2002 and a result made more incredible given white-ball head coach Gary Kirsten quit just a week before the tour amid well-worn Pakistani turmoil.

But Pakistan appeared galvanised under Jason Gillespie, their Australian Test coach who is filling the shoes of Kirsten, and were ignited by a rampant four-pronged attack that routed a shorthanded Australia without their Test stars for 140 in just 31.5 overs.

There were no infamous wobbles for Pakistan, who romped home in the 27th over.

Australia capped a sluggish series with a sloppy performance in the field. Opener Saim Ayub had an early reprieve, while Adam Zampa spilt a sitter at deep square leg to reprieve Abdullah Shafique as Australia faced the humiliating prospect of a first ever 10-wicket ODI loss at home.

But Lance Morris, who showcased his trademark pace by hitting speeds in the mid-140 kph, at least saved Australia from an unwanted place in the record books with the wickets of Shafique and Ayub in the 18th over.

Interim captain Josh Inglis opted not to use Morris until the 15th over with allrounder Marcus Stoinis surprisingly given the new ball alongside Spencer Johnson.

Skipper Mohammed Rizwan and Babar Azam, his predecessor, were nerveless with a flurry of boundaries to complete a match that finished two hours ahead of the scheduled close time.

It completed a memorable first series in charge for Rizwan, who had no hesitation to bowl first and his decision was vindicated. Shaheen Shah Afridi and Naseem Shah claimed three wickets apiece, while in-form Haris Rauf finished with 2 for 24 as his sheer speed once again shook up the batters.

Numerous batters succumbed to hostile short balls, while allrounder Cooper Connolly had to retire hurt on 7 after copping a blow to his left hand attempting to pull Mohammad Hasnain. He was taken for scans and did not field in Pakistan's innings.

Pakistan's attack smartly did not get carried away with the bounce on offer as their quicks bowled unrelenting line and lengths to totally smother Australia, who once again would be disappointed with their shot selections on a surface that was not a minefield. No Australia batter scored a half-century across the series.

Pakistan entered in the unfamiliar position of favourites in a country where they have endured so much misery over the years.Their optimism was heightened by Australia making five changes after skipper Pat Cummins, Steven Smith, Josh Hazlewood, Mitchell Starc and Marnus Labuschagne were rested as they start to prepare for the first Test against India.

Australia had to rejig their batting-order, but openers Matt Short and Jake Fraser-McGurk remained at the top of the order and desperate to fire having struggled across the opening two games.

They appeared intent on backing their ultra-aggressive methods and scored 12 runs in the opening over. But things quickly went downhill with Fraser-McGurk caught at second slip after attempting to drive a good length delivery from Naseem.

He failed to move his feet in a dismissal that is common in Perth and his wicket brought to the crease allrounder Aaron Hardie, who was elevated to No. 3 in a role he fulfils with aplomb for Perth Scorchers in the BBL. Even though he was on his home ground, Hardie looked nervous and fell in a moment of indecisiveness and edged to second slip in a reward for Afridi, who conjured beautiful seam movement.

The pressure was on Inglis, who was already amid a big day in his captaincy debut having been earlier selected in Australia's 13-member squad for the Perth Test against India. Inglis has often performed a rescue role for Scorchers in the BBL, but he couldn't get going and skied a short Naseem delivery to Rizwan.

Short managed to get through the early barrage as he set his sights on furthering his bid to become Australia's permanent ODI opener. But on 22 he picked out square leg to gift a wicket to Rauf, who was feeling giddy at his good fortune.

Rauf ramped up his speed and claimed Glenn Maxwell for a duck as Australia stared down the barrel of being routed for under 100. The only momentary concern for Pakistan was Afridi grimacing in agony after being whacked on his left thumb taking a throw at the stumps.

But he returned and was faced with a counterattack from Sean Abbott, who top-scored with 30. But Afridi ended Abbott's resistance and then knocked over Morris to send the large contingent of Pakistan fans in the terraces into raptures and they continued to roar through the afternoon.
