Pakistan's sloppy fielding and poor hearing helped Australia captain Steve Smith take his side to 288 for three at stumps on the opening day of the the day-night Test in Brisbane.
Smith scored 110 not out and along combined with half- centuries Matt Renshaw and Peter Handscomb, put the hosts on top at the Gabba.
Australia slipped to 75-2 in the opening session after Smith won the toss and decided to bat.
Smith steadied the innings with his 16th test century although he was dropped on 53 in the final over before dinner by keeper Sarfraz Ahmed.

He had a bizarre reprieve on 97, when he feathered an edge to Sarfraz but none of the tourists appealed.
"I walked into the dressing room quickly (after stumps) and he was saying he smashed it," Renshaw said.
"That's a bit of a surprise, that nobody went up really."
Azhar Ali suggested none of the tourists "really noticed anything".
"None of our guys went up even slightly," Azhar said.
"It was one of the situations where nobody realised what happened. Sometimes it does happen ... a bit of luck for the batsman."
Azhar also lamented the chance put down off his own bowling.
"It would have been a wonderful wicket .. it could have changed the game a little bit," he said.
"We all know he's a very good batsman and was quite well set.
"But these things happen and we have to go on and look forward."
Renshaw scored 71 in his first home Test, with Handscomb to resume on 64 amid high hopes of posting his maiden Test century.
