Captain Steve Smith and opener David Warner both scored fifties on Thursday as Australia reached 225 for five before poor light brought play to an early close on the opening day of the first test against South Africa.
Smith, who was prolific with the bat in leading Australia to success in the Ashes, scored 56 while Warner contributed a characteristically quickfire 51.
Shaun Marsh added 40 and his younger brother Mitchell was 32 not out, along with Tim Paine on 21, when the umpires took the players off in gloomy conditions with 14 overs still remaining.
