Centuries to Marnus Labuschagne and Travis Head helped Australia reach 3-330 at stumps on day one of the second Test against West Indies at Adelaide Oval.
Labuschagne continued his sparkling start to the summer with 120 not out in the pink-ball Test, his third consecutive three-figure score.
The men's world number one-ranked Test batter scored 204 and an unbeaten 104 in the first Test in Perth.
