Quinton de Kock is back in the T20 side while Dale Steyn will have to wait a bit longer to make his comeback.
Steve Smith won the toss and chose to bat first in the opening T20, at Kingsmead. South Africa’s captain, Faf du Plessis, says he was very uncertain what to do if he had won the toss and was hoping to lose it anyway.
De Kock replaces Hashim Amla in the starting XI in the only change to the team that won the series against England.
South Africa: Quinton de Kock, AB de Villiers, Faf du Plessis, JP Duminy, Rilee Rossouw, David Miller, David Wiese, Chris Morris, Kyle Abbott, Kagiso Rabada, Imran Tahir.
Australia: Aaron Finch, Usman Khawaja, Steve Smith, David Warner, Glenn Maxwell, Mitchell Marsh, Peter Nevill, John Hastings, Adam Zampa, Nathan Coulter-Nile, Andrew Tye.
