Pat Cummins, Josh Hazlewood and Tim David, all on comeback trails from injury, have been named in Australia's preliminary squad for the T20 World Cup.

Cummins, who is recovering from a back injury and featured only in the third Ashes Test in Adelaide, is set to undergo a scan later this month that will determine his availability for the final squad. However, chair of selectors George Bailey said Cummins, along with Hazlewood and David, were "tracking well" in their recoveries and expressed confidence that all three would be fit in time for the tournament.

David sustained a grade-two hamstring injury during a Big Bash League match on Boxing Day, while Hazlewood missed the Ashes with Achilles soreness following a hamstring injury.

"The T20 side has enjoyed a long run of recent success which enabled the panel to choose a balance of players across the variety of conditions Sri Lanka and India may present," Bailey said.

"Pat Cummins, Josh Hazlewood and Tim David are tracking well and we are confident they will be available for the World Cup.

"This is a preliminary squad so should changes need to be made they will ahead of the support period."

The squad is otherwise spin-heavy for the tournament, which will be co-hosted by India and Sri Lanka. Australia will play their Group B matches in Colombo and Pallekele.

Mitchell Marsh will captain the side once again, with Cameron Green and Cooper Connolly returning to the squad after missing the T20Is against India earlier in the summer. Josh Inglis is the sole wicketkeeper selected.
