The Australia national cricket team toured South Africa from October to November 1921 and played a three-match Test series against South Africa.
Their team was unchanged, except that Warwick Armstrong, the captain on the tour of England, did not go on to South Africa.
Australia won the Test series 1–0 with two matches drawn.
All 14 of the Australian team played at least one Test in the series; South Africa also used 14 players.
