Half-centuries from Simon Katich, Shane Watson and Michael Hussey enabled Australia to have the better of the opening day of the third and final Test against the West Indies in Perth.
Katich fell one short of a century, Watson made 89 and Hussey was unbeaten on 81 as they closed on an imposing score of 339 for three.
However, that was tempered by the loss of Ricky Ponting, who had to retire hurt on 23 having been hit on the arm by fast bowler Kemar Roach and the cheap dismissal of Michael Clarke, for 11.
Katich and Watson put on 132 for the first wicket but both would fall within sight of centuries, Katich out for 99 for the second time in his Test career when he was caught by Roach off Sulieman Benn, after Roach had Watson caught by Denesh Ramdin.
Clarke was caught by Chris Gayle off Narsingh Deonarine, who replaces the injured Shivnarine Chanderpaul in the side. Adrian Barath also misses out with Travis Dowlin back in the side and Gavin Tonge making his debut in place of Darren Sammy.
Clinton McKay makes his debut, replacing Peter Siddle, for Australia, who lead the series 1-0.
