Sydney - Pace spearhead Mitchell Starc, veteran spinner Nathan Lyon and all-rounder Mitch Marsh were all left out of Australia's Twenty20 squad on Thursday to play South Africa and India.
Coach Justin Langer said they, along with Peter Siddle, would be better off playing Sheffield Shield cricket to be ready for a busy home summer featuring four Tests against India and two against Sri Lanka.
In their absence, Marcus Stoinis and Jason Behrendorff get a chance to impress after being included in the 13-man squad for a single T20 against the Proteas and three against the Indians.
"We know coming off the back of the tour to the UAE, a huge summer at home, and the World Cup and Ashes just around the corner that we have to get the balance right between playing our best T20 team and preparing for the upcoming Test series," said Langer.
"While I know all four have a desire to be playing for Australia in every format, with a really tough Test series against India coming up, we believe their best preparation is to go back and get some really good cricket under their belts in the Sheffield Shield."
Aaron Finch's Australia are desperate for form. They have lost 17 of their 19 one-dayers and were thrashed 3-0 by Pakistan in a T20 series in the United Arab Emirates last month.
Left-armer Behrendorff returns after recurring back injuries, with all-rounder Stoinis, who was overlooked for the Pakistan series, also back.
"Marcus is such a versatile player, he's a powerful middle-order batsman and he provides us with another solid bowling option," said Langer.
"Jason Behrendorff has also earned a spot in the squad after returning to full fitness. Tactically we believe it's important to have a good left-arm swing bowler at our disposal for the four matches."
