The Brave squad includes Pakistan star Shadab Khan and West Indies all-rounder Andre Russell, as well as England batsmen Ollie Pope, James Vince and others.
Warner, however, is still committed to captaining the Sunrisers Hyderabad in this year's Indian Premier League.
“If the IPL is on David is planning on going,” player manager James Erskine told The Age.
“If things change dramatically, which can happen in the space of an hour, the answer is you change your mind. It's no different to everybody else.”
The start of the IPL has been postponed from 29 March to 15 April as a preventative measure against the coronavirus pandemic.
Warner back as Sunrisers captain
Warner lost the Hyderabad captaincy to Indian seamer Bhuvneshwar Kumar New Zealand batsman Kane Williamson after being found guilty of ball-tampering during Australia's Test tour of South Africa in 2018. He served a ban from international cricket for the infringement – and was recently returned the Hyderabad captaincy.
“I'm thrilled to be given the captaincy for this coming IPL 2020. I'm extremely grateful to be given the opportunity to lead the team once again,” he said last month.
“I'd like to thank Kane and Kumar for the way you guys led throughout the last couple of years, you guys did an outstanding job. And I'll be leaning on you guys for support and your insight to the game as well. And to the management thank you once again for giving me this opportunity. And I'll try my very, very best to lifting that IPL trophy this year.”
The left-handed Warner is the leading run-scorer among non-Indian batsman in the history of the IPL. He has also played for the Delhi Daredevils (since renamed the Delhi Capitals) and scored 4706 runs in 126 innings overall. The tally includes four centuries and 44 half-tons.
India's Virat Kohli, Suresh Raina and Rohit Sharma are the first, second and third-highest run-scorers in the IPL. The tournament started in 2008. The Mumbai Indians are the reigning champions. Mumbai are captained by Sharma, who is currently sidelined by injury.
