Australia have beaten South Africa by five wickets in their Twenty-20 match in Cape Town.
The hosts posted a score of 146-7, with Aussie debutant Pat Cummins doing most of the damage with the ball.
The teenager claimed three wickets in the 19th over to take the South Africans from 133-3 to their final total.
JP Duminy top scored for the Proteas with 67, before being caught by Shane Watson off the bowling of Cummins.
The visitors' innings began disastrously when David Warner went for a duck off the third ball.
Watson steadied the ship with a knock of 52, and scores from Shaun Marsh [25], David Hussey [25] and Cameron White [28] pushed Australia closer to their target, which Steven Smith reached with three balls to spare.
The second match of the two-game series takes place on Sunday in Johannesburg.
