Sri Lanka spin king Muttiah Muralitharan heads into Saturday's mouth-watering Group A showdown with Australia admitting Ricky Ponting's men are the team "everybody wants to beat".
Sri Lanka have lost six of their previous seven World Cup meetings with the Aussies and will be determined to reverse the trend when the sides meet in Colombo.
However, it will be no mean feat, with Ponting's troops coming into the match on a high following back-to-back opening tournament victories over Zimbabwe and New Zealand.
Muralitharan knows all too well about coming up short at the hands of Australia and he admits he is desperate to get the better of them.
"They (Australia) have won in all conditions," he said.
"They have won the last three World Cups. They are the team everybody wants to beat. Everyone in the team is upbeat. We are anxious to beat them."
Ajantha Mendis is set to retain his place in the Sri Lanka side despite failing to take a wicket against Kenya last time out, with hat-trick hero Lasith Malinga again likely to play instead of Thisara Perera.
For their part, Australia are not expected to make any chances to the side that comfortably saw off the Black Caps earlier this week.
Both sides know a win will move them level with group leaders Pakistan, and Australia batsman David Hussey has identified Muralitaran as Sri Lanka's main threat.
"It's been a very, very useful three days," he said of his side's preparation in Colombo.
"Lot of the boys are practicing sweep shots, easing their feet to the spin and getting back, back and forth out of the crease.
"Murali is such a great bowler, who has got 800 Test wickets, a phenomenal competitor.
"But Australia has had pretty good success against Murali in the past. Hopefully that can continue on Saturday."
