A trio of uncapped pacemen have been included in Australia's 15-man squad for the tour of South Africa.
Mitchell Starc and Josh Hazlewood are being rested for the tour, with Chris Tremain, Joe Mennie and Daniel Worrall named in the squad for a one-day international against Ireland and five with the hosts.
Australia national selector Rod Marsh said the trio deserved their chances.
"Chris, Joe and Daniel all had terrific summers last year and have also impressed us during the recent Australia A series with consistent performances," he said.
"They are young players with a bright future who thoroughly deserve their selection and we look forward to seeing them work with John Hastings and Scott Boland, who have both performed well for Australia since returning from injury."
In Australia's domestic 50-over competition last season, Worrall took three wickets at 46.66, while Mennie claimed seven scalps at 50.85.
Mennie and Worrall were the leading wicket-takers in the Sheffield Shield with 51 and 44 respectively, with Tremain taking 36.
Squad in full:
George Bailey, Scott Boland, James Faulkner, Aaron Finch, John Hastings, Travis Head, Mitchell Marsh, Shaun Marsh, Joe Mennie, Steve Smith, Chris Tremain, Matthew Wade, David Warner, Daniel Worrall, Adam Zampa.
