It comes as chief health officer Brett Sutton asked Victorians who need a negative Covid test in order to travel interstate to get tested in the afternoon in order to shorten lengthy wait times.
The chief health officer made the plea, asking travellers to avoid the "busier morning period" and take pressure of the embattled system.
"We kindly ask people who are getting a PCR test for travel purposes to get tested after 12pm daily," he said.
"This will help reduce testing demand for symptomatic people and contacts during the busier morning period."
