Josh Hazlewood, Mitchell Starc rested for South Africa tour
This decision is taken with the aim of having the duo fresh and ready for the upcoming home season where Australia have a hectic schedule of Test cricket.
National selector Rod Marsh said that the selectors took the decision to manage the workload of the bowlers effectively.
Marsh also feels that it will be a good opportunity for the rest of the bowlers in the side to step up and make an impression.
"Both Mitchell and Josh have had big tours of Sri Lanka and have a heavy workload ahead of them with 10 tests to be played this summer.
“As such, it is important they are managed appropriately and we believe missing the tour of South Africa is the right time for them to take a break.
"This also provides a good opportunity for some of our up-and-coming fast bowlers to push for selection."
Earlier in June, Starc returned to action after a lengthy lay-off due to ankle surgery while Hazlewood has had an increased workload in the past year.
Since last September, Hazlewood has bowled 509.4 overs across the three formats of the game and is the only fast bowler to have clocked over 500 overs.
With Australia aiming to reclaim their number one ranking during the upcoming season, a fully fit duo of Starc and Hazelwood will be key to their plans.
Nathan Coulter-Nile will not be a part of the South African tour due to his back injury but Australia have players like John Hastings, Scott Boland, Kane Richardson and all-rounder James Faulkner in their ranks to step in for Starc and Hazlewood.
