As it happened: Proteas v Australia - 3rd T20 International - PPC Newlands
Much like the Proteas had done at the start of their innings, the visitors opening batsmen Usman Khawaja (33 off 25 balls) and Shane Watson (42 off 27 balls) attacked from the outset and immediately put the home side under pressure.
They put on 76 for the first wicket in just 8 overs to set the platform for Australia's formidable middle order to continue the onslaught.
Imran Tahir (2/38 in four overs) was again targeted although no South African bowler had any answer to the Australians.
Captain Steve Smith (44 off 26) and David Warner (33 off 27) took the visitors to within sight of victory before Warner was run-out attempting a suicidal second run.
Smith soon followed, but Glenn Maxwell (19*) and Mitchell Marsh (4*) saw the visitors home.
Earlier, led by a by a fine 97* (62 balls) by Hashim Amla, the Proteas posted 178 for 4 after captain Faf du Plessis had won the toss and elected to bat.
Amla and Quinton de Kock were quick to take the attack to the visitors with De Kock leading the charge.
The pair put on 47 for the first wicket in just 4.1 overs before De Kock fell for 25 (13 balls).
Faf du Plessis (4) soon followed with the recalled Rilee Rossouw replacing him.
Rossouw however, struggled to get going, eventually departing for 16 (21 balls) as Australia clawed their way back into the match with some disciplined bowling.
Adam Zampa, the young leg spinner, was particularly impressive, finishing with 0/23 in his four overs.
Amla was joined by David Miller and the pair accelerated impressively, putting on 50 for the fourth wicket in just 29 balls before Miller fell for 30 (16 balls) in the final over.
