Australia will be significantly shorthanded for the game with players who were involved late into the IPL given the chance for a short break at home before heading to the Caribbean.
They are set to have just nine players available for the match against Namibia tomorrow and against West Indies on Thursday.
Pat Cummins, Travis Head and Mitchell Starc were involved in the IPL final on Sunday and will briefly return to Australia before joining the World Cup squad.
Glenn Maxwell and Cameron Green, who were part of Royal Challengers Bengaluru’s run to the playoffs, are also spending time at home.
Those five are due to arrive when the Australia squad reaches Barbados ahead of their first group match against Oman on June 5, Marcus Stoinis has also yet to arrive in the Caribbean.
It means that Australia will likely need to call on members of the coaching staff to field during the warm-up matches if they want a full complement.
Brad Hodge has joined the support staff for this tournament while head coach Andrew McDonald, national selector George Bailey and assistant coach Andre Borovec could also be called in.
