Australia have fought back after their decision to bowl first in Cape Town initially backfired, with South Africa 4-221 at tea on day one of the series-deciding third Test.
On a chaotic morning when Steve Smith ruled himself out with a neck injury, Australian captain Pat Cummins sent the Proteas in on a straw-coloured pitch under largely blue skies.
Australia's start then became their worst after electing to bowl first in a game in 56 years, with Aiden Markram (78) and Marques Ackerman (95) putting on 158 for the first wicket.
