South Africa completed a dream tour of Australia yesterday after winning both the Test series and the One Day Internationals.
The Proteas, who won yesterday's final ODI by 39 runs, also overtook the World Champions as the No1 ranked one-day team.
Batting first, South Africa amassed 288-6 thanks to an impressive 97 by Hashim Amla as well as cameos by AB de Villiers (60) and JP Duminy (60 not out).
Then debutant bowler Lonwabo Tsotsobe, who struck in his first over, ended with four wickets to help South Africa to a 4-1 series win.
Earlier in the month the visitors missed the opportunity to become the top Test team when they lost the third match. They still won the series 2-1 to become the first side to defeat Australia on home soil since 1992.
Australia will now play New Zealand in a home ODI series before travelling to South Africa later in February for the return leg.
