Mitchell Starc took 3-33 as Australia bowled out Pakistan for 203 in the first match of their three-match one-day international series on Monday at the MCG.
Newly appointed skipper Mohammad Rizwan top-scored with 44 for the visitors, but they struggled with precision bowling, all out in the 47th over.
In Pakistan’s first 50-over match since last year’s World Cup, Australian skipper Pat Cummins won the toss and elected to bowl on a fine day.
Starc broke through in the third over with Saim Ayub clipping his stumps, mistiming a rising ball in front of a subdued crowd at the cavernous Melbourne Cricket Ground.
This brought Babar Azam into the ranks, freed from the burden of captaincy after his departure last month.
He upped the tempo before Starc struck again, with Abdullah Shafique caught behind for a tame 12 in a superb opening spell from the speedster.
Azam was in decent touch and put on 39 with Rizwan before spinner Adam Zampa entered the fray and broke the partnership, bowling Azam for 37 with his fourth delivery.
His replacement Kamran Ghulam lasted just six balls, no match for a brutal bouncer from Cummins, gloving wicketkeeper Josh Inglis to leave Pakistan in trouble at 70-4 after 19 overs.
A patient one that Rizwan played in before opening the batting, hitting the first six of the day against Starc. But the wickets kept falling.
Salman Agha was smartly caught squared for 12 by Matt Short off Sean Abbott and Rizwan then went for a sweep of part-time spinner Marnus Labuschagne, caught by Inglis.
Shaheen Shah Afridi struck an entertaining 24, but Starc struck again, rattling his middle stump, before a flurry from the tails pushed Pakistan past 200.
Naseem Shah, coming on nine, added 40, an innings which included four sixes, with 20 off a Zampa.
