Two more Australians - John Millman and Max Purcell - were scheduled to compete today, but have withdrawn from the tournament.
Millman cited a foot injury as the reason for his withdrawal from his first-round singles match against German Jan-Lennard Struff, while Purcell was unable to compete in doubles due to personal reasons.
