Quinton de Kock cracked his second successive century at the World Cup on Thursday as South Africa demolished five-time champions Australia by 134-runs.
After the Proteas had made 311-7 – with de Kock top-scoring with 109 off 106 balls – Australia lost six wickets with just 70 on the board and then focused trying to limit the damage to their net run-rate.
They were eventually dismissed for 177 with 55 balls to spare as fast-bowler Kagiso Rabada took 3-33, while Marco Jansen, Keshav Maharaj and Tabraiz Shamsi all took two wickets each.
Marnus Labuschagne's 74-ball 46 was the top score for Pat Cummins' side who fell to their biggest World Cup defeat. There was controversy over Marcus Stoinis's wicket after South Africa called for a review, which left Australia 70-6 in their chase.
