Speaking to reporters after the Australians had practised at Arnos Vale on Saturday morning, Australia middle order batsman Michael Hussey said it had been disappointing to lose the top spot to South Africa.

The two teams meet in the final group A match in St Kitts on March 24.

"I guess we become the hunters rather than the hunted," said Hussey, who captained Australia in the absence of the injured Ricky Ponting in their 3-0 whitewash to New Zealand last month.

"We really enjoyed being the number one side in the world and we tried harder and harder to make the gap further and further between the number one and the number two.

"We now have to try to get that number one place back, we have to try and make the gap bigger again."

Australia play a warm-up match against Zimbabwe on Monday followed by a game against England four days later before travelling to St Kitts.

Opener Matthew Hayden and all-rounder Andrew Symonds will not be considered for Monday's match while they recover from a broken toe and torn left arm muscle respectively but Ponting and all-rounder Michael Clarke played a full part in Saturday's practice.

Ponting had been suffering from a hip injury while Clarke had a sore back.

Hayden walked briskly around the outfield several times and Symonds had a few gentle throwdowns in the nets with a tennis ball.

Hussey said Australia had put the New Zealand defeats behind them and were ready for the challenge of the biggest World Cup yet.

"The Australian team is so meticulous about their preparation," he said. "They are an experienced side who know their own game so well and what they need to do.

"I just want Australia to win, that's all. If that's in the first over or the 50th over, the most important thing is the result."
