David Warner and Mitchell Marsh have been left out of Australia's new-look squad to take on Sri Lanka in next month's T20 series.
Australia will also be without coach Justin Langer for the five-match series, with the 51-year-old being given a break after a busy period.
Assistant Andrew McDonald will act as head coach for the series, which runs from February 11 to 20.
While Australia will be without two of their T20 World Cup stars in Warner and Marsh, Josh Hazlewood is back involved after returning from injury.
Ben McDermott, who impressed during the Big Bash League campaign, is also included in the 16-man squad that was named on Tuesday.
"I don't think that I wasn't ready to play for Australia before, but I certainly feel ready now," said McDermott, who has already made 19 appearances for his country.
"I feel like I'm at the top of my game. I've developed a lot of learnings through some experiences.
"They haven't all been good ones, I won't shy away from that, but I've definitely learned from those experiences and hopefully I come back well."
The other members of Australia's successful World Cup campaign to miss out on selection are Mitchell Swepson, Daniel Sams, Dan Christian and Nathan Ellis
National selectors chair George Bailey said: "This squad will begin preparation for the ICC T20 World Cup defence at home later this year and includes several players who have an early chance to impress in these five matches against a quality opposition."
