The Australian Medical Association (AMA) has called for a pause on the lifting of coronavirus restrictions around Australia following a surge in cases in Victoria.
Two more Melbourne postcodes were put in lockdown yesterday after 108 new cases were recorded.
Victoria has been ramping up testing.
It has also locked down several public housing blocks.
The AMA estimated more than 300,000 residents of Melbourne were under "hard lockdown", including 3,000 in the towers.
AMA president Dr Tony Bartone said the new outbreaks showed the threat of COVID-19 is far from over.
“These new outbreaks send a strong signal that the other States should rethink the pace of easing of their COVID-19 restrictions until community transmission in Melbourne is under control to avoid the risk of a similar situation playing out in their own communities,” Dr Bartone said.
“We all want to get our lives back to normal, but it has to be a gradual and cautious process – and it must be with strict adherence to the medical advice and public health guidelines."
He said that governments are dealing with huge challenges trying to balance the protection of public health with the economy.
" As pubs and restaurants open up to more people, as the restart of elite and community sporting events picks up, and as the return to workplaces for thousands of workers accelerates nationally, the COVID-19 spikes in Melbourne are a warning for all Australians how quickly virus outbreaks can occur anywhere in the country," Dr Bartone said.
He said it was a "stark reality check" about how rapidly things can change.
Dr Bartone said it was disappointing that many of the Melbourne hotspots were " directly linked to failures to follow established and successful public health guidelines", was particularly worried about those that related to AFL players.
"The AFL teams were given privileged exemptions, with strict guidelines, but some players have disrespected these privileges and then sought to plead exceptional circumstances in their defence."
"We all can and must do better," Dr Bartone said.
“Before rushing back to the pub, the footy crowds, or the big weddings and parties, Australia should pause and play it safe until the Melbourne hotspots are back under control.”
