Australia face a steep challenge after South Africa posted a large first-innings total on the fourth day of the second Test.
South Africa declared at 9/425, and Australia had progressed to 2/15 in reply when the latest scores were posted, according to the ABC News live blog.
With limited time remaining in the match, Australia's top order will need a substantial response to avoid handing South Africa control of the contest. The two sides are scheduled to meet again in a third Test on 27 October.
