Captain Ricky Ponting [ Images ] has promised to maintain Australia's [ Images ] aggression against the West Indies [ Images ] in the team's quest to climb back to the top of the ICC [ Images ] Test world rankings.

The Australian team's belligerent approach was a feature of its victory by an innings and 65 runs in the opening Gabba [ Images ] Test.

''It was trying to be as positive as we can, and to test ourselves more than anything. It would've been easy to go out there and bat and drag it out a little bit longer, let the bowlers put their feet up for a while,'' said Ponting, who has attracted criticism in the past for his reluctance to make teams follow on.

''We know the West Indies were probably a long way off their game, there is no chance for us to be complacent with what we've achieved - it's one Test match out of the summer,'' The Age quoted him as saying further.

Australia's No 4 ranking clearly rankles with the captain, and this series is the first chance for Australia to erase some of the pain of the Ashes defeat.

''One thing I spoke about was the rankings; I wanted the guys to put their best foot forward to improve that," Ponting said.

Gayle has to rally his players before the second Test starts in Adelaide on Friday.
