Medical professionals who attended an engagement party allegedly held in breach of Melbourne's lockdown restrictions have been reported to the regulator.
The Australian Health Practitioner Regulation Agency (AHPRA) on Monday confirmed it has received "a number of complaints about registered health practitioners" who attended the event in Caulfield North last week.
Three people, including a mother and son in St Kilda East, have tested positive for COVID-19 following the event.
A total of 69 guests are self-isolating, as are 90 of their close contacts.
AAP understands at least two medical professionals attended the engagement party, which is also being investigated by police.
"We are aware that Victoria Police have stated that they intend to take action with respect to individuals who attended the event," an APHRA spokesperson told AAP.
"We will liaise with them in relation to any registered health practitioners who were present."
The spokesperson said due to privacy laws they are limited in what they can say publicly about "any action we are or may be taking regarding individual practitioners".
A video of the event, seen by AAP, shows dozens of people who aren't wearing masks gathered in what appears to be a private residence, listening to a man give a speech.
"Clearly this is legal as a group therapy session. That's why my father's here," the man jokes.
Another party member adds: "He's a mental health clinician."
In announcing a two-week extension of the state's lockdown on Monday, Premier Daniel Andrews slammed the event's hosts and guests for making "selfish" and " s***ty choices".
"If you listen and watch the video, it's clear that there are some medical professionals there, might I be so bold as to say that they've perhaps not necessarily acquitted themselves very well," he said.
"Do no harm. Spreading the virus hurts everybody."
Chief Commissioner Shane Patton said police intended to fine every adult who attended, adding up to more than $350,000 ($NZ 365,000).
The newly elected president of the Jewish Community Council of Victoria, Daniel Aghion, called for calm and said anyone concerned about exposure should contact authorities.
"We are disappointed to learn that a small group have not been following mandatory lockdown restrictions," he said in a statement.
"We too feel the immense frustration at the current situation, and are focusing our support on significant efforts being made to contain the virus," he said.
The Rabbinical Council of Victoria urged the community to follow restrictions.
"We implore anybody considering flouting the law to refrain from doing so. We unreservedly condemn such actions, which bring risk and shame to the entire community," the council said.
