Sri Lanka are hoping to spoils Adam Gilchrist's last match on his home ground in Perth as they target top spot in the tri-series table.
Retiring Australia wicketkeeper Gilchrist will step out onto the WACA pitch for the final time on Friday in the latest tri-series match.
After losing to India in their last match, Australia know that another defeat would relegate them to bottom spot in the table, whilst the Sri Lankans would go top courtesy of a win over the world champions.
Mahela Jayawardene's men got themselves back into contention in the competition with a win over India in Canberra on Tuesday, and he says that the Australians are not as daunting a proposition as they have been ion the past.
The Aussies will definitely be fired up for the game though, and none more so than Gilchrist, who will bid an international farewell to his home ground.
Emotions will be running high as a full house will pay their respects with 10,000 'Gilly Gloves' being handed out and two large murals for fans to sign.
"It is hitting him game by game I think," Skipper Ricky Ponting said of Gilchrist.
"The moment he made his announcement in Adelaide was a shock for us - and it is great to see there will be a sell-out crowd tomorrow, there are going to be banners all over the place.
"Hopefully he can get some runs and do the right thing by the fans."
Ponting's side will include two changes for the match, with spinner Brad Hogg and all-rounder James Hopes coming in for Brad Haddin and Stuart Clark.
The Aussies will be determined to give Gilchrist a good send-off, but Sri Lanka's confidence is high and they are targeting top spot.
"It is a good opportunity for us to go top of the table," said Jayawardene.
"We've got back into the tournament and the guys can really build up on that confidence.
"They (Australia) are a bit under pressure. The batting, there are two or three guys who have been consistently performing, but the rest haven't been.
"In the past the Aussies have found ways to get back into games, but the last six months I don't think they've got that belief in themselves."
"If we can push them back from the beginning, we can create more pressure."
Sri Lanka are hoping to have seamer Ishara Amerasinghe available to return after a hamstring strain, but a final decision will be made on the morning of the game.
