Scotland's Jonny O'Mara says being able to leave his hotel room for five hours a day is making "a huge difference", as Australian Open doubles partner Artem Sitak is confined to his for two weeks.
It means he and new partner O'Mara, 25, will be limited in their court time.
"I had five days in full lockdown while all flights were tested and even with that I was toast," the Scotsman said.
"So I don't know how 14 days is going to feel."
O'Mara and others who have been cleared are permitted five hours out of their rooms each day - which equates to three-and-a-half hours training.
