The WTA has created a tournament exclusively for the players unable to leave their rooms during quarantine for the Australian Open.
Victoria Azarenka, Bianca Andreescu, Angelique Kerber and Britain's Heather Watson are among those eligible.
The ATP events scheduled for the week before the Australian Open will be pushed back 24 hours.
Seventy-two players are currently confined to their rooms after positive cases on the chartered planes that brought them to Australia.
"This has been a particularly challenging time for the athletes in hard lockdown and we, along with the WTA and ATP, aim to do everything we can to help," said Australian Open tournament director Craig Tiley.
