Cricket Australia said that on their website that on the tour of South Africa their pacers will be rested because of the long season ahead of them.

Australia recently placed a test matches against Sri Lanka and Strac bowled very well against them and it was Starc's come back series after Injury so cricket Australia thinks to give them rest on this tour.

“With a number of bowlers currently coming back from injury it is important for us to continue to build up a battery of quality fast bowlers for Australia,” said Rod Marsh, chief selector of Australia.

That will help other bowlers to prove them self, Bowlers like Kane Richardson, Ben Cutting, Andrew Tye and some others too.
