Sri Lanka will target Australia's bowling attack in Friday's tri-series tournament ODI clash in Perth (starts 4.20am GMT).
Sri Lanka captain Mahela Jayawardene believes the absence of James Pattinson, Brett Lee, Mitchell Johnson and Pat Cummins has significantly weakened the hosts' bowling attack.
The skipper said: "(Ryan) Harris has come back after injury, he is a decent bowler, but they are still missing quite a few front-line guys. That's an area we can target."
After losing their opening match to India by four wickets on Wednesday, Jayawardene knows his team needs to improve significantly in order to beat the Australians.
"We have to be smart to beat them," he said.
"We know what their strengths are. We know what our strengths are. It's all about how you are going to apply on the day.
"You get into different situations in a match. Certain situations we didn't handle better than India. That's why they won the game. Against Australia, we will be in certain situations again, we have to handle them in a much smarter and better way. Try and be on top of them, and try and finish a game off."
Friday will only be the second match for Sri Lanka under new coach Graham Ford, while Jayawardene himself is also only one match into his new tenure as the captain.
Tillakaratne Dilshan and Geoff Marsh were both given the axe following a tough tour of South Africa, and Jayawardene is still uncertain about the future of Sri Lankan cricket, but insists he will do all he can to get it back on track.
"All that (the long-term future) is far ahead," Jayawardene said.
"I haven't given it much thought. The decision to take over was a very tough one. The easiest thing for me was to say no. But the situation we are in right now I felt I needed to take that responsibility. And try and do my best and see what happens. Spoke to the usual people that I speak to about the game, they all felt the same way. It took me 24 hours to take the call."
Meanwhile, Michael Clarke insists he is choosing to ignore Jayawardene's comments about the Australian bowling attack.
Clarke says he is not bothered by opposition comments and chooses to do his talking on the pitch.
"That's Mahela's opinion, he's a very good player and played against a lot of opposition teams, so he feels that way, we just have to make sure we play some really good cricket, whether that be with the bat or the ball," Clarke said.
"I'm not really concerned about the opposition right now, whether that be India or Sri Lanka. There's a lot of areas of our game that we've been working on as a one-day team, and that'll be our focus at training again."
Australia enjoyed a winning start to the ODI tournament after defeating India by 65 runs with the assistance of the Duckworth/Lewis method, but Clarke knows matches will get tougher as the series continues.
"We will be tested as a team all around the world. It's been a really good start to the summer winning the Test series, but you are expected to perform in your own backyard, it's now going to be a test to see how we go when we play overseas," Clarke said.
The 30-year-old added that the team is fully prepared to face the Sri Lankans despite not watching their opponents' four-wicket defeat to India on Wednesday.
"I didn't see one ball," admitted Clarke.
"I was asking on Twitter how I can watch the game, but unfortunately we don't have Gem (General Entertainment and Movies, an Australian television channel) in our hotel.
"So I was getting the scores off Twitter but didn't see one ball unfortunately. We looked at a lot of footage yesterday of the Sri Lankan team, so everyone in our change room knows the opposition, knows their strengths and weaknesses and what we need to do to beat them."
