Australia captain Steve Smith says there is now a "line in the sand" when it comes to physical contact on the cricket field after Kagiso Rabada had his two-Test ban overturned.
Rabada had been suspended for the remainder of the series for brushing against Smith's shoulder in the second Test, but was cleared to play after an appeal.
Speaking on the eve of the third Test in Cape Town, live on Sky Sports Cricket, Smith said: "They've obviously decided what's deliberate contact and what's not and apparently it wasn't.
"The ICC have set the standard, haven't they? There was clearly contact out in the middle.
"I certainly won't be telling my bowlers to go out there and after you take a wicket go and get in their space. I don't think that is on and part of the game. But the standard has been set."
The South Africa paceman was initially given three demerit points for the incident in Port Elizabeth by match referee Jeff Crowe, triggering an automatic two-Test ban.
But judicial commissioner Michael Heron was not completely satisfied the contact was deliberate and reduced the charge to acting against the spirit of the game, which took Rabada one point below the threshold for a ban.
Smith told cricket.com.au he was surprised not to be asked for his version of events during the hearing.
"It's pretty interesting when you're, I guess, looking for evidence and those kind of things," Smith said.
"The other person involved (is) not getting asked about it is pretty interesting, I thought."
Smith said he and senior Australia players Nathan Lyon and David Warner had spoken to incoming match referee Andy Pycroft, who will handle the remaining two Tests of what has been a bad-tempered series.
He said the referee would also speak to South Africa captain Faf Du Plessis to "ensure that the series is continued to play in pretty good spirit."
