Seven Australia players could pull their names out of white-ball tours of West Indies and Bangladesh. Quarantines and bio-bubble fatigue would mean several top players will choose not to tour West Indies (five T20Is and three ODIs) and Bangladesh (five T20Is). Reports from Australian media have disclosed that Pat Cummins, David Warner, Steve Smith, Glenn Maxwell, Marcus Stoinis, Kane Richardson and Jhye Richardson are likely to miss the tours that include as many as 13 international matches. Some of them are also previously reported to be skipping second leg of IPL in September-October. On Tuesday, Cricket Australia added Ben Mcdermott, Dan Christian, Cameron Green, Ashton Turner, Wes Agar and Nathan Ellis in their preliminary squad, which now stands at 29. The extension of the squad has been made to add covers for those who will likely withdraw. The IPL players had to stay in Maldives before catching a flight back to Australia, where they completed a two-week hotel quarantine. "It has become clear that recent experiences abroad, including but not limited to extended periods in bio-secure hubs and hard quarantine, have had an impact on the health and wellbeing of some players and their families," CA selector Trevor Hohns said. Ashton Agar, who is a part of the squad, has said that the reports of players pulling out are not surprising to him given the amount of time spent in quarantine. "I'm not surprised at all (by potential withdrawals), and very understanding of that," he said. "It's hard not to be (understanding), really; these guys are away for a very long time and unless you really put yourself in their shoes, it'd be tough to imagine the mental toll it takes on you. "I think if anyone had to do so many stints of quarantine – a lot of these guys have done 10-12 weeks already, and Covid has been around for a year-and-a-bit now – it's a crazy amount of time just spent sitting around a hotel room with your own thoughts, without fresh air or whatever." Australia's Caribbean tour kicks off on July 9. They will face Bangladesh in the early weeks of August. After that they will return to Australia for 14 days of quarantine on arrival. The T20 World Cup squad will also do the same once they return home ahead of a busy home summer. Australia preliminary squad: Aaron Finch (captain), Ashton Agar, Wes Agar, Jason Behrendorff, Alex Carey, Dan Christian, Pat Cummins, Nathan Ellis, Cameron Green, Josh Hazlewood, Moises Henriques, Mitchell Marsh, Glenn Maxwell, Ben McDermott, Riley Meredith, Josh Philippe, Jhye Richardson, Kane Richardson, Tanveer Sangha, D'Arcy Short, Steven Smith, Mitchell Starc, Marcus Stoinis, Mitchell Swepson, Ashton Turner, Andrew Tye, Matthew Wade, David Warner, Adam Zampa
