Well what a convenient narrative…
It may well be true. The decision to hold the BLM march was irresponsible.
But, I've only seen this report in The Australian and I just don't trust the Murdoch press. It is a well known manipulator of the news to further it's owner's particular political ideologies.
The last report I heard from The Vic Dept of Health (Prof. Brett Sutton) was that the genome of the viruses tested to date
all relate to the quarantine outbreak and that this particular genome wasn't present in Australia at the time of the BLM marches. I haven't heard any update on that advice.
So, as I say, it may be true but personally I'll wait to hear it from the Health Dept or from a more reliable news source than Rupert's empire.
It is being reported more widely, all the same story vaguely stating... "Health officials confirm.."

This is from the Daily Telegraph (also a Murdoch paper):
"It comes as two protesters who attended the Black Lives Matter rally have had their COVID-19 cases linked to the outbreak in Melbourne’s public housing towers.
Health authorities have confirmed the link without saying if the protesters lived, visited or were close contacts of those in the towers, The Australian reports.
The public housing cluster has seen at least 242 cases.
Chief Health Officer Brett Sutton previously said it was unlikely the protesters caught the virus at the rally in Melbourne’s CBD which was attended by 10,000 people on June 6.
The link does not necessarily mean the protesters were the original source of the public housing tower outbreak, which is the state’s largest cluster to date."
So, a bit more truthful (unusual for the Tele, but there you go). The incubation period of the virus is normally up to about 14 days. The BLM march was on June 6.
I don't get how several big towers with many apartments can have so many people all get sick.
Is it shared living, where they share kitchens and such? If they are self-contained units, then I would have thought a lot of people would normally not have much to do with their neighbours.
Did it get into the ventilation or something?
I was living in HK during the SARS outbreak in the early 2000's. They concluded that a lot of infections were caused by transmissions through bathroom ventilation systems and improperly sealed or cracked plumbing.
*Warning next part is a bit gross*... some dude had a bad case of diarrhoea which resulted in the infection of most residents in his apartment building.
Afterwards an instruction was put out for all bathroom ventilation ports to be temporarily sealed, which in turn stopped the spread.
Is there such thing as a good dose of diarrhoea?
