Australia coach Justin Langer vowed on Saturday to put a smile back into cricket as South African skipper Faf Du Plessis said he expects the sledging to be toned down in their one-day series.

The two sides meet in Perth on Sunday for the first time since the Test series in South Africa this year boiled over with Australian players attempting to alter the ball with sandpaper.

Langer, Lehmann's replacement, has pledged to change the win-at-all-costs culture and said he hoped the first game of the summer at home would be a step in winning back fans.

"It's sad, isn't it. Everyone seems to be at each other. There's lots of criticism," he said of the atmosphere surrounding Australian cricket.

"What we can do is we can prepare well, we can play good cricket, and be entertaining and put on a good show so Australians can start smiling a bit.

"One thing sport can do and the Australian cricket can do is put smiles on faces rather than everyone throwing stones at each other."

Australia have lost 16 of their past 18 one-day internationals and are desperate to get off on the right foot in Perth, with two more one-dayers and a Twenty20 against the Proteas to follow.

Du Plessis said he expected less verbal banter on Sunday than in the past.

"An Australia-South Africa series is always going to be competitive but I do suspect this series will be a little bit more toned down, especially from the Australian side," he said on Saturday.

 Despite Australia being without Smith and Warner and their poor one-day form, Du Plessis said his team won't be taking the home side lightly.

"Whenever you get a chance to play against Australia it feels like you're playing against a very good cricket team," he said.

"When you look at what they've got in their squad at the moment on paper there are some fantastic names there with the ball and with the bat."
