Despite winning the one-day international (ODI) series against Pakistan 2-1 earlier this week, spinner Saeed Ajmal had looked almost unplayable and the offspinner was damaging again with 2-13 off four overs.
Fellow spinners Mohammad Hafeez and Raza Hasan, on debut, also claimed two wickets while pacemen Sohail Tanvir (3-13) and Umar Gul (1-17) also cashed in on Australia's over-aggressive strokeplay.
Opener David Warner (22) was the only batsman to reach 20 in a worrying display from the game's ninth-ranked side just two weeks shy of Australia's opening T20 World Cup clash with Ireland in Sri Lanka.
Gul and Shane Watson had both been rested from the ODI series and it was the Pakistan paceman who began in better form, trapping the Australian vice-captain lbw for eight with his fifth delivery after coming on to bowl the third over.
Mike Hussey, fresh from two consecutive ODI half-centuries, was caught at cover for one.
David Hussey (three) and skipper Bailey (14) were both caught on the leg-side boundary and Matthew Wade (six) and Glenn Maxwell (four) followed in the same fashion.
Ajmal dismissed Maxwell and Cameron White (bowled for 15) in successive deliveries but tailender Xavier Doherty was at least able to deny the spin genius a hat-trick.
Pacemen Pat Cummins, Ben Hilfenhaus and Watson took one wicket each in Pakistan's innings.
