Spearhead Shaheen Shah Afridi took three wickets as Pakistan dismissed Australia for 157 in their third and final one-day international in Lahore on Thursday.
Shaheen finished with 3-30 and was ably supported by Abrar Ahmed (2-19) and Shadab Khan (2-28) as Australia's innings folded in 42 overs after they won the toss and batted on a slow-paced Gaddafi Stadium pitch.
Spinners Abrar and Shadab built on Shaheen's early strikes as Pakistan made a strong comeback after losing the second ODI by 41 runs, also in Lahore on Tuesday.
Pakistan won the first match by five wickets in Rawalpindi.
Josh Inglis top-scored with a 71-ball 65 which included eight boundaries and a six, with Marnus Labuschagne and Alex Carey scoring 19 each and Adam Zampa making 10.
Shaheen had Matthew Short caught off the second ball of the match before Inglis added 46 for the second wicket with Labuschagne and another 52 for the third with Carey.
But Australia lost their last seven wickets for a meagre 38 runs with two run outs also hurting their innings.
