Pace spearheads Naseem Shah and Shaheen Shah Afridi knocked over eight wickets and restricted Australia to 391 before Pakistan ended day two of the deciding Test at 90-1 in Lahore on Tuesday.
The duo led a late charge to close the second session as Australia lost their last five wickets for 71 runs after reaching a commanding 320-5 at lunch. Naseem finished with figures of 4-58 and Shaheen 4-79.
The series is tied at 0-0 after the first two Tests in Rawalpindi and Karachi ended in high-scoring draws.
At stumps on Tuesday, the game was evenly poised and the series hanging in the balance as Abdullah Shafique, 45, and Azhar Ali, 30, returned to the pavilion five overs early due to bad light.
Shafique and Azhar had to rebuild after Pakistan opener Imam-ul-Haq was trapped leg-before by Australian skipper Pat Cummins on 11. But the pair looked untroubled, putting on 70 for the second wicket.
Azhar survived a stumping scare while batting on 14 but the review showed his foot was planted well inside the crease after he was beaten by a well-flighted delivery from spinner Mitchell Swepson.
Before Naseem and Shaheen brought Pakistan back into the game, Cameron Green, 79, and Alex Carey, 67, had frustrated the hosts in the morning session, adding an invaluable 135 for the sixth wicket.
Fortunes turned after spinner Nauman Ali had Carey leg-before in the fourth over after the break.
The wicketkeeper-batsman had hit seven boundaries in his 175-minute knock.
Green was then bowled by Naseem after a resolute 223-minute stay intermittently lit up by nine boundaries.
Pakistan were looking to make early inroads at the start of play with the second new ball only five overs in.
But Australia, who resumed at 232-5, took advantage of a placid Gaddafi Stadium pitch to bat through 28 overs unscathed.
Pakistan thought they had removed Carey for 27 when umpire Aleem Dar gave him out caught behind off fast bowler Hasan Ali but the Australian reviewed straight away.
The replay showed he had missed the ball, which had also not carried to wicketkeeper Mohammad Rizwan.
Carey took full advantage of his reprieve by smashing spinner Sajid Khan for two boundaries before reaching his third Test fifty with a single.
Australia are on their first tour of Pakistan since 1998, having previously refused to tour the country over security fears.
