Australia's 14-man squad for the Champions Trophy will be sweating it out again in the hot and humid conditions in preparation for their second practice match.

Ricky Ponting's side thrashed the Maharashtra Cricket Association by 103 runs in a trial game on Thursday and will have another hit-out against a Mumbai eleven.

Australia's opening Group A clash on Wednesday is against qualifier No.2, which will be either Sri Lanka or defending champion West Indies.

The squad's only injury worry is batsman Michael Clarke, who was rested from Thursday's match with a slight quadricep train.

But the NSW strokeplayer trained well at the Cricket Club of India Ground in Mumbai and coach John Buchanan said team management would assess Clarke's fitness before Sunday's game.

Buchanan also promised more hard workouts for the squad early in the Champions Trophy campaign, as the three-time World Cup winners seek to win the trophy for the first time.

"We're planning to make the finals so it's going to be important that we've got plenty of time out in the conditions so that we can benefit from that later in the tournament," Buchanan said.

The team is yet to be announced for the game but Simon Katich will be hoping for a chance to play after being rested from Thursday's clash where potential rival for the opening position Shane Watson scored a well-compiled 70.
