Victorian protesters will hold eight mini-protests in order to avoid fines

Refugee activists will spread themselves out in Melbourne in an attempt to avoid the same fines copped by the Black Lives Matter organisers.

Victoria Police issued fines of $1652 each on three people behind the huge anti-racism rally last weekend and have threatened to do the same on Saturday to the Refugee Action Collective if they do not abide by outdoor gathering rules.

The group said its rallies will have no more than 20 people in eight different locations to protest against the indefinite detention of asylum seekers.

Health Minister Jenny Mikakos said a gathering of more than 20 would breach the chief health officer's legal directions, so police would have the ability to take action.

Meanwhile, a man in his 30s who attended Melbourne's BLM rally has coronavirus and his close contacts are in quarantine.

Victorian Deputy Chief Health Officer Annaliese van Diemen said there was a low risk that he passed the virus on to others, given he had no symptoms and was wearing a mask.

Four fresh cases were confirmed in Victoria on Friday, though none are believed to be linked to the protest.
