The Proteas took care of the hosts for 161 after they had resumed at 2-121 on fay four.

Kyle Abbott dismantled Ausrealia with figures of 6-77 with Kagiso Rabada was taking 4-34.

David Warner (45), Usman Khawaja (64) and Steve Smith (31) pitched in before the middle-order again crumbled.  

The win marks South Africa’s third consecutive series victory in Australia, a feat not achieved since the West Indies sides of the 1980s and 1990s.
