Australia have won the toss and decided to bat first in the second Twenty20 international against South Africa at the New Wanderers Stadium here on Sunday.
An injury to Shane Watson meant he was out of the side and the opening slot with the David Warner will be shared by wicketkeeper batsman Matthew Wade.
Aussies also decided to bring in young Mitchell Marsh in place or Watson.
South Africa, on the other hand, swapped slow-left arm spinner Robin Peterson with pacer Wayne Parnell.
Australia are leading the two match series by 1-0 after winning the Newlands match by five wickets.
