Marnus Labuschagne and Steve Smith hit two centuries as Australia punished the West Indies on day two of the first Test in Perth.
Labuschagne made 204 and Smith 200 not out to take Australia – 293-2 overnight – to 598-4 declared.
They shared a third-wicket stand of 251 before Travis Head smashed 99 from 95 balls.
Debutants Tagenarine Chanderpaul and Kraigg Brathwaite survived 25 overs as West Indies went 74-0 in the end.
Chanderpaul, son of the great West Indian Shivnarine Chanderpaul, will take over on the 47th and Captain Brathwaite on the 18th.
Smith, who started the day at 59, progressed steadily to his 29th Test century – level with Australian legend Sir Don Bradman – and then his fourth double.
Labuschagne, who took over 154, was let go on 194 but soon reached his second double century test.
He was caught by Brathwaite’s off-spin before Head hit 11 fours in a 196-for-208 partnership with Smith.
The header was thrown by Brathwaite via an underside which signaled captain Pat Cummins’ statement.
Amid a hostile new ball spell, the 26-year-old southpaw Chanderpaul, whose stance and manners resemble his father’s, got off to a slow start before becoming increasingly aggressive with six fours and a six hung on a slender leg.
