Australia's World Cup squad will have a day off training on Tuesday after their thumping seven-wicket win over Sri Lanka in Grenada on Monday.

The victory, Australia's eighth in eight games in the tournament, puts Ricky Ponting's world champions into the first- versus-fourth semi-final to be played in St Lucia on April 25.

Australia (12 points) have a massive run-rate advantage and will complete their Super Eights commitments in the second stage of the World Cup with a game against New Zealand on Friday.

The Kiwis (10pts) and Sri Lanka (8pts) will meet in the other semi-final in Jamaica on April 24, while England and South Africa are contenders for the fourth spot in the semis.

Australia's only injury concern is all-rounder Shane Watson, who strained his left calf muscle while bowling his second over against Bangladesh in Antigua on March 31 and is planning to have another bowl in the nets on Tuesday in a bid to prove his fitness for Friday's game.

"We've clearly finished on top now which is great but we've still got another big game coming up (against New Zealand on Friday)," Ponting said after top-scoring with 66 not out in Australia's win over Sri Lanka.

"I'll have a chat to him (Watson) and see how he feels after he has bowled today," Ponting said.

"I might even come down and have a look at him tomorrow if I'm not off fishing or playing golf or something.

"He just evens the balance of our side out really well."
