Durban, Johannesburg and Cape Town will host the T20 series between South Africa and Australia next March. The first and third T20s - to be played at Kingsmead and Newlands on March 4 and 9 - will be night matches starting at 6pm local time while the second game at the Wanderers will begin at 2.30pm on March 6.
The series, which will conclude a packed South African summer that also includes visits from New Zealand and England, will serve as a lead-up to the World T20 - which begins on March 11 - for both teams.
"This announcement completes our home international fixtures for the 2015/16 summer," said CSA Chief Executive Haroon Lorgat. "We will be competing at home against New Zealand, England and Australia. These are three top-class teams and it promises to be one of our most exciting and competitive home seasons in a long time.
"The T20 Series against Australia provides for both teams the perfect lead-in to the ICC World Twenty20 which will be played in India immediately afterwards."
