Cape Town - Proteas captain, Quinton de Kock has won the toss and elected to bat in the 2nd T20 International against Australia at St George's Park in Port Elizabeth.
South Africa made three changes after suffering a record 107-run defeat in the first match in Johannesburg on Friday.
"We're all good," said South African captain Quinton de Kock. "We understand today is very important."
De Kock said he expected the pitch "might get a bit slower" later in the match.
Opening batsman Reeza Hendricks, all-rounder Dwaine Pretorius and fast bowler Anrich Nortje came into the South African team in place of Jon-Jon Smuts, Andile Phehlukwayo and Dale Steyn.
Australia were unchanged.
"We bowled great lengths the other night," said Australian captain Aaron Finch. "The pitch is a lot drier than it was in Johannesburg. It will perhaps skid a bit and turn a bit later."
South Africa: Quinton de Kock (captain, wicket-keeper), Reeza Hendricks, Faf du Plessis, Rassie van der Dussen, Pite van Biljon, David Miller, Dwaine Pretorius, Kagiso Rabada, Anrich Nortje, Tabraiz Shamsi, Lungi Ngidi
