The Refugee Action Coalition (RAC), who organised the event, said the protest would go ahead regardless of the court ruling. Just under 300 people have clicked attending on the protest's Facebook event page.
Following the incident on Friday, Assistant Commissioner Mick Willing warned that another 600 officers would again be on the ground on Saturday to "take whatever action we need to take to ensure that the COVID health order is applied".
The protests, which are calling for an end to the indefinite detention of asylum seekers, will be held at Mantra Preston, the Melbourne Immigration Transit Accommodation, Border Force offices in Docklands, Casselden Place Immigration Office, the Liberal Party headquarters, the State Library, State Parliament and acting Immigration Minister Alan Tudge's office.
Organisers are urging those planning to attend to register to ensure numbers do not exceed the 20-person limit at any one location.
Victoria Police have warned that organisers of the protests could be fined if the rallies breach social distancing rules after three organisers of last weekend's Melbourne Black Lives Matter march were fined $1,652 each.
Both Prime Minister Scott Morrison and opposition leader Anthony Albanese have called on people not to attend the protests over the weekend.
"People shouldn't protest. People should follow the health advice, and the health advice is very clear from the chief medical officer," Mr Albanese said on Saturday morning.
"Our democracy is important, that people can have their say. There are a range of ways you can have your say without breaching the advice of the health experts."
Organisers of both protests are urging attendees to wear a face mask, use hand sanitiser and practice physical distancing.
