The Victoria state government on Friday confirmed one new case of COVID-19 in the group of people in quarantine in Melbourne ahead of the Australian Open, a few hours after Spanish player Paula Badosa said she had tested positive for the virus.
Badosa was the first player entered in next month's Grand Slam to confirm a positive test, although four were among the 10 cases announced earlier this week.
There has been confusion over the exact numbers, however, with several test results later reclassified by Victoria health authorities as "viral shedding" from previous infections.
