The home side prepared a brownish looking wicket at Durban in order to make life hard for the likes of Starc and co.
It follows the run out-dismissal of AB de Villiers, where Lyon dropped the ball hitting de Villiers on the chest as he lay on the ground after diving in an attempt to make it to the crease at the bowlers end.
Apart from Starc, one of the other major reasons why Australia were able to get ahead in the Test match was the batting of Mitchell Marsh.
But Aiden Markram's brilliant 143, coupled with fearless support from Theunis de Bruyn and a superb return to form by Quinton de Kock, allowed the Proteas to take the game into the fifth morning, albeit for just 22 balls of action before they were dismissed for 298.
However, the team from down under have now taken the lead of 1-0 and would love to conitnue in the same vein during the series.
Not only did he shine with the ball, but Starc also added runs with the bat in the first innings that turned out to be crucial in the match.
Smith's South African counterpart Faf du Plessis says sledging should remain on the field.
"I'm sure captaincy did have a bit to do with it, but having said that it's something I do really enjoy and going forward, if I was to establish myself in the one-day side, I just think it would become a little bit easier next time".
"It keeps me going, keeps me in my plan".
Mitchell Starc missed out on a hat-trick - the left-arm paceman, who bowled Keshav Maharaj and Kagiso Rabada from his final two deliveries on day four, opening up on Monday with a ball that rapped De Kock on the pads but was heading down leg.
ICC officials can hand out fines and demerit points if they deem the actions provocative enough, but unlike Rabada, none of the Australians have any blemishes on their record.
"Obviously it's natural when you play against the Australians that there's a lot of chat on the field", Markram said.

The staff members, who barged into the chamber after hearing a scream, found Shetty lying in a pool of blood. Union minister Ananth Kumar held Siddaramaiah and his party "fully responsible" for the attack .
"It's not been spoken about once yet".
"It was quite a tricky stage for me, trying to establish myself in the side and then along with that trying to lead a very strong (Proteas) side, against a very strong Indian side", he said this week.
Klaasen was included in the squad after matchwinning knocks in the pink ODI and second T20 against India, matches he played in because de Kock was injured. Captain Steve Smith also gave his contribution of 56 runs in the first innings. It was nothing aggressive.
This isn't about petty name calling, this is about South Africa not taking a backward step, showing unity in battle (in a cricketing sense), making the two Australian batsmen feel alone out in the middle and like they're up against 11 players.
Starc grabbed nine wickets and scored 35 in Australia's first innings, while Marsh set the game up with his first-innings 96 then broke a stubborn 147-run stand between de Kock and Aiden Markram. To go with three world-class pacemen, Australia's attack boasts of a finger spinner who's now the best in world cricket.
"He gets a chance tomorrow now", said Tim Paine.
As the Australians celebrated the big wicket, Lyon looked down at de Villiers before dropping the ball on him.
"But as you saw, it bounced a bit more and got an outside edge so I'm very grateful it stuck".
Known for his insatiable work ethic, Bancroft has been willing himself to find a way out of the rut that had engulfed him by the back end of the Ashes, and now he has at long last found some light at the end of the tunnel.
"He did (seem fired up)".
"It was good to see actually".
