Victoria Police have warned protesters they risk being fined if they attend a planned protest tomorrow in Melbourne.
There were reports earlier this week that police would not be finding people who breach COVID-19 safety rules, but police have since refuted these claims.
"In the exercise of police discretion, those who intentionally break the law will be held to account, and we have again contacted the organisers of the protest this morning to ensure this point is understood," Victoria Police said in a statement.
"As Assistant Commissioner Luke Cornelius made clear earlier this week, it is our strong preference that the protest does not occur at this time, while the restrictions in relation to public gatherings remain in place.
"There are obvious and potentially dire public health consequences should this event lead to an outbreak of coronavirus."
Police said while it wouldn't be "practical" to issue fines to thousands of protesters, they will not hestitate to issue penalties to organisers and any other people they deem "appropriate".
This comes as Victoria Police deputy commissioner Shane Patton warned protest organisers they will be fined if their event goes ahead.
The Herald Sun reports Mr Patton said he hopes the event doesn't go ahead.
"People have to be held accountable for their actions,” he said.
“We will issue infringements to the organisers."
Mr Patton said the fines would not exceed $1652.
Victoria has already recorded the most fines related to breaches of coronavirus directions.
Since late March in Victoria, individuals have faced fines of $1652 and businesses $9913 for failing to adhere to the chief health officer’s directives “designed to slow the spread of COVID-19”.
In a statement overnight, chief health officer Brett Sutton said the protest carried a "real risk" for all Victorians in the middle of a pandemic.
There are still cases of COVID-19 from community-to-community transmission being recorded in the state.
