Smith and Warner are now playing for Rajasthan Royals and Sunrisers Hyderabad respectively in the IPL after serving their 12-month ban for their role in the ball-tampering scandal that rocked Australian cricket past year. While Warner has been in scorching form for Sunrisers Hyderabad, Smith is still feeling his way to form at Rajasthan Royals.
Alex Carey is the sole wicketkeeper in the squad, while leg-spinner Adam Zampa and off-spinner Nathan Lyon are the two spinners in the squad.
Having served their resultant one-year bans, Warner and Smith are trying to get back in the groove at the ongoing Indian Premier League (IPL). But fortunately for him, the selectors named him in the Australia A squad for the England tour in July.

Stand-in skipper Aaron Finch will lead the 15-member squad despite Steve Smith returning to the side.
He added that there had been some tough calls to make given the depth of talent available, but was happy to see Smith and Warner return to the worldwide fold.
"(Smith and Warner are) both ... world class players and it has been pleasing to see them produce some good form in the IPL".
Hazlewood has been included in two Australia A squads - one for one-day cricket and the other for four-day matches - which will tour England later this year, in a bid to show his fitness ahead of the subsequent Ashes series, also in England. Mitchell Starc, Jhye Richardson, Jason Behrendorff, Pat Cummins and Nathan Coulter-Nile are the five pacers.
"We believe the 2019/20 contract list provides us with a versatile group of players who can represent Australia across all three formats over the contract period", national selector Trevor Hohns said.
Another notable absentee is fast bowler Josh Hazlewood, who has been sidelined with a back injury since January.
