The big-hitting Yasir Shah (28) had his leg stump removed by Mitchell Marsh and the innings ended with Mitchell Starc rattling through Abbas (10). Pakistan named two debutants in Fakhar Zaman, who replaces the injured opening batsman Imam-ul-Haq, and left-arm seamer Mir Hamza, who comes in for Wahab Riaz after the paceman went wicketless in the drawn first test in Dubai.
In the previous three Tests, Pakistan lost two matches to Sri Lanka and one to West Indies.
Abbas then trapped Siddle to finish on 9-2.
Pakistan were reeling on 5-57 part way through the morning session, their top order decimated by Lyon (4-78) in the space of six deliveries as he took four wickets for no runs.
On Tuesday, Debutant opener Fakhar Zaman and Sarfraz missed hundred by six runs each but still revived Pakistan on the first day, after Pakistan found themselves reeling at 57/5 having won the toss and chose to bat first.
Sarfraz then holed out to Labuschagne, who finished with 3-45.
Australia cricketer Marnus Labuschagne celebrates after he dismissed Pakistan cricketer Sarfraz Ahmed during day one of the second Test cricket match in the series between Australia and Pakistan at the Abu Dhabi Cricket Stadium in Abu Dhabi on October 16, 2018.
Ahmed was, by far, more aggressive, and kept the scoreboard moving with constant rotation of the strike before his 129-ball knock was ended in which he hit seven boundaries.
Sarfraz was frustrated to miss his fourth Test hundred but happy with the fightback. Pacer Mitchell Star provided Australia an early breakthrough in the third over when Mohammad Hafeez fell to a freakish catch at short leg by Labuschagne for four. "It's good that we scored 282 and then got two wickets, including that of Usman Khawaja because he can play a long innings, so I think it has become even for both the teams now", said Sarfraz.
