Australia have taken a first-innings lead of 287 runs in their day-night Test against Pakistan, with Steve Smith opting against enforcing the follow-on early on day three in Brisbane.

Pakistan were rolled for 142 after unravelling spectacularly under lights at the Gabba on Friday and resumed at 97-8 on Saturday, trailing the hosts by 332 runs.

Sarfraz Ahmed and Mohammad Amir stroked a couple of boundaries but Jackson Bird broke their 54-run partnership - comfortably Pakistan's best - in the eight over of the day.

Smith successfully reviewed a caught-behind shout, with HotSpot revealing an edge that was missed by standing umpire Richard Illingworth.

Amir was staggered to be given his marching orders by third umpire S Ravi.

The tailender pointed to his elbow, was sitting on the turf when given out then slowly trudged off the field, often turning his head to watch replays on the scoreboard.

Ravi was involved in the other dismissal, when Rahat Ali was run out by a direct hit from David Warner at mid-off.

Rahat's bat bounced off the turf as he slid it, with Ravi spending a long time reviewing the footage before judging the No.11 batsman short of his ground.

Sarfraz brought up his half-century and was dropped by Nic Maddinson in the deep on 51, with the keeper finishing 59 not out.

Australia haven't enforced the follow-on since trouncing West Indies by an innings and 212 runs in Hobart last summer.
