Aaron Finch is retiring from international cricket in a decision which leaves Australia searching for a new Twenty20 captain.
Finch will announce his international T20 retirement at a media conference at the MCG on Tuesday morning, having already quit from the 50-over format.
The 36-year-old retires having led Australia to a T20 World Cup victory in 2021 but failing to defend the title in last year's tournament on home soil.
Finch retires as one of Australia's premier short-form batsmen, making 3120 runs at an average of 34.28 in 103 T20 internationals, and 5406 runs at 38.89 from 146 one-day internationals.
He also played five Test matches but his explosive power with the bat was better suited to the short formats.
Australia's next T20 is scheduled for South Africa in September.
