Former Test quick Ryan Harris has accused South Africa of dropping the ball on the ground in the field to encourage reverse swing.
But he believes Australia must also adopt the controversial tactic.
South African captain Faf du Plessis was warned in both innings of the first Test in Perth by umpires Aleem Dar and Nigel Llong for the practice after the ball began to reverse swing.
Proteas players deliberately bounced the ball back to 'keeper Quinton de Kock in an attempt to rough up one side and influence swing.
Harris had no problem with the Proteas' tactic during their first Test victory - he just wanted Australia to be better at it.
"All we have to do is throw the ball on the ground more often - simple as that," Harris said.
"That's what they (Proteas) were doing - pick the ball up, look at it and then throw it on the ground.
"That's the trend these days. It is no secret.
"We have to do it better. They (South Africa) utilised it very well, we just have to make sure we do it better."
South Africa got the ball to reverse swing earlier and better that Australia in Perth on their way to a 177-run first Test win.
It's not the first time Australia have aired their concerns about the Proteas' tactics.
David Warner was fined almost $3000 for accusing du Plessis of ball tampering during the 2014 series in South Africa.
Harris said it was up to the umpires at the ground to police the tactic.
"I have no problem with it (reverse swing tactics) unless they are physically scratching the ball," Harris said.
"Every cricket team throws the ball on the ground now.
"If it gets to the stage where umpires don't like it then they will tell them.
"But if it's within the rules no problem."
Harris confirmed on Tuesday he and ex-Test teammate Brad Haddin would join the Australia team coaching staff on their tour of New Zealand in January.
