Dan Christian has been added to Australia's preliminary squad for the white-ball tours of West Indies and Bangladesh along with uncapped pacemen Wes Agar and Nathan Ellis.

The selectors announced an initial party of 23 to face the Windies and the Tigers, featuring a number of players who played in an Indian Premier League that was cut short due to the coronavirus pandemic.

They have now added Christian, Agar, Ellis, Ben McDermott, Cameron Green and Ashton Turner.

All-rounder Christian, 38, and wicketkeeper-batsman McDermott will end spells in England with Nottinghamshire and Derbyshire respectively to fly home and complete the mandatory two-week quarantine period before the final squad's scheduled departure for the Caribbean late in June.

Christian has not played for his country since October 2017, while Agar and Ellis will be hoping to make their international debuts.

Promising all-rounder Green made his ODI bow against India last December, while Turner has featured in the 50-over format six times and played 11 Twenty20 Internationals.

Confirmation of the tours are subject to agreement on bio-security arrangements and relevant government approvals.
