Australia completed a 5-0 whitewash over Pakistan with a clinical 20-run win in the fifth and final ODI at Dubai.
Haris Sohail scored 130 off 129 balls for his second ODI hundred but failed to get his side over the line as Pakistan finished at 307-7 in 50 overs.
Australia's massive total revolved around Usman Khawaja's 98 and a fiery 33-ball 70 by Glenn Maxwell backed up by Shaun Marsh's 61 and skipper Aaron Finch's 53.
The series win gives Australia their eighth straight ODI victory following their 3-2 series win in India.
Australia's resurgence could not have been more perfectly timed as they aim to defend their World Cup title in England and Wales starting May 30.
Sohail, who struck 11 boundaries and three sixes, had set up the chase during a second wicket stand of 108 with Shan Masood (50 off 54 balls) and another 102 with Umar Akmal (44-ball 43) before Australia struck back with two wickets in a short span of time.
Umar holed out to off-spinner Nathan Lyon and a run later Sohail's innings was ended by Kane Richardson.
Stand-in skipper, Imad Wasim, hit an unbeaten 50 off 34 balls but couldn’t turn the tables for Pakistan.
The centurion from the previous game, Abid Ali, was dismissed off his first ball, caught behind off Behrendorff’s bowling.
Earlier, Maxwell's ten fours and three sixes helped Australia to achieve 107 runs in the last ten overs. He was finally bowled by Junaid Khan who finished with figures of 3 for 63.
Khawaja, who smashed ten boundaries in his 111-ball innings, set a solid platform with a 134-run opening stand with Finch for the pair's second hundred run stand in the series.
Finch was finally bowled by Usman Shinwari, finishing with 451 runs in the series.
Khawaja, who struck his first two ODI centuries in India earlier this month, was all set for his third but fell to a miscued drive off Shinwari, who was the pick of the bowlers from Pakistan and finished with figures of 4-49.
Khawaja added 80 for the second wicket with Shaun Marsh who scored 61 off 68 deliveries.
Australia won the first two matches in Sharjah by eight wickets before winning the third in Abu Dhabi by 80 runs and fourth in Dubai by a close margin of six runs.
