Victoria’s public transport system will not enter the Melbourne CBD between 8 and 14 on Saturdays.
Victoria Police have taken steps to stop public transport in response to a planned anti-lockdown protest in the CBD.
They are concerned about the number of people expected to attend in violation of state lockdown restrictions.
There are also concerns about violence.
Police Commissioner Shane Patton warned people that they would be fined more than $ 5,000 if they entered the city to protest.
Buses will bypass the city, while trams and trains do not run to the CBD.
Barricades, traffic locks and moving police patrols are also expected.
“We will do everything we can to prevent access to the city,” said Commissioner Patton.
He said police were aware it would cause significant inconvenience to key workers, but police had no choice.
