Four people have been fined over an infamous engagement party held in breach of Melbourne's lockdown restrictions, as another three people linked to the outbreak tested positive.
Victoria Police Chief Commissioner Shane Patton on Thursday revealed the engaged couple and parents of the bride-to-be have been fined $5452 each.
Sixty-nine guests attended the party, hosted by a prominent Jewish family, in Caulfield North last week.
A video of the event showed dozens of maskless people gathered in what appears to be a private residence, with a man joking it was a "group therapy session".
Mr Patton said attendees had been assisting police with their investigation but the handing out of further fines had been delayed.
"That investigation is still ongoing. It's obviously hampered to a degree by the fact that they're in isolation," he told reporters.
Investigators are planning to organise interviews with the other guests over Zoom to expedite the process, Mr Patton said.
Police intend to fine every adult who attended the engagement party for breaching the chief health officer's directions, to an expected total of more than $350,000.
The state's COVID response commander Jeroen Weimar said three further cases had been linked to the St Kilda East outbreak. It takes the number of infections connected to the cluster to 10.
Of the 12,000 primary close contacts isolating in Victoria, Mr Weimar said about 120 to 130 people were linked to the outbreak.
Medical practitioners who went to the party are also being investigated by the industry regulator.
