Have your say on South Africa v Australia

South Africa captain Temba Bavuma will be given a luxury when he comes into bat next at some point today.

At Gqeberha, he went out to the middle at 12-2 prior to producing his best ever Test knock of 179.

In the first Test, was in at 84-2 and 73-2, so he's going to get the best part of 100 runs on top of that as a bare minimum.

Five singles and start the over before Mitchell Starc produces a no ball.

The extra delivery is punished for four by David Bedingham, a 10-run over for the hosts.

Pat Cummins brings himself back on for the final over before lunch.

South Africa are currently going at over five runs an over. Cummins himself has conceded at a similar rate.

Obligatory comment about how Australia are old and were there for the taking in the Ashes.

Winning the toss and bowling on a flat track after bringing back a spinner for a seamer is an unusual approach. Boland could probably bat 4 in this team and do just as good a job, then you've got his bowling as well but it's all a bit late now.

Hosts South Africa have made one change to the side that won in the second Test of this series. Gerald Coetzee comes into the team to replace fellow seamer Anrich Nortje, who suffered a groin injury in Gqeberha.

South Africa: Aiden Markram, Marques Ackerman, David Bedingham, Temba Bavuma (c), Matthew Breetzke, Ryan Rickelton (wk), Wiaan Mulder, Gerald Coetzee, Marco Jansen, Simon Harmer, Kagiso Rabada

Meanwhile, Australia have made four changes from the second Test. Cameron Green, Josh Inglis, Cooper Connolly and Nathan Lyon all come in. Steve Smith, Scott Boland, Nic Maddinson and Beau Webster are the quartet coming out of the side.

Australia: Travis Head, Matt Renshaw, Marnus Labuschagne, Cameron Green, Josh Inglis, Alex Carey (wk), Cooper Connolly, Pat Cummins (c), Mitchell Starc, Nathan Lyon, Josh Hazlewood
