Steve Smith has failed again and Australia collapsed to be 4-24 at tea after West Indies posted 311 on day two of the pink-ball Test at the Gabba.
Smith, yet to fire as an opener, shuffled across his crease too far and was given out lbw on review to the last ball of Kemar Roach’s first over.

Marnus Labuschagne (three) was then brilliantly caught next over by a diving Kevin Sinclair at fourth slip off Alzarri Joseph.
The last two balls before the break by Roach (3-13) brought pure joy to the tourists.
Cameron Green (eight), who returned a negative COVID-19 test before play, drove straight to captain Kraigg Brathwaite at cover.
Travis Head was well caught down the legside next ball by Joshua Da Silva to leave Roach on a hat-trick.
“No worse way to go,” Ricky Ponting said on Channel 7.

“It’s a half volley, going down legside. Just catches up with it. Just clips the inside edge and a good catch. Da Silva lunging to his right. Gets both gloves around it. Kemar strikes again. And Travis Head is gone first ball. Australia 4/24, believe it or not.”
After the tea break, Usman Khawaja successfully negotiated the hat-trick ball.
Earlier, an accomplished maiden half-century on debut by offspinner Sinclair lifted West Indies to a competitive first-innings total.
Sinclair (50) and veteran paceman Roach (eight) added 31 for the ninth wicket after the visitors resumed at 8-266 on Friday.
The stand was broken when Roach called for a single but Sinclair wasn’t interested.
Roach slipped over mid-pitch and Labuschagne underarmed to Head with Roach stranded.
Sinclair struck a four and a straight six off Nathan Lyon to reach his half-century, but was stumped next ball.

Roach and Sinclair were untroubled for most of the first hour, but Australia missed a trick when Green dropped Sinclair in the gully when on 30.
Pat Cummins drew the edge but Green, usually so reliable, watched in dismay as the ball went in and out of his bucket hands.
Australia set defensive fields, with even Cummins employing a deep point.
Sinclair was cool as a cucumber on debut, but his first-class record suggests he is no mug with the bat.
The 24-year-old now boasts nine first-class half-centuries, with a highest score of 86.
West Indies did well to recover from 5-64 to set Australia a competitive total.
No.5 batter Kavem Hodge (71) and wicketkeeper Da Silva (79) were the stars on day one, while left-armer Mitchell Starc (4-82) was the pick of the Australian bowlers.
