hmm another outlet says it's wife of the first mystery case
The article you originally linked already stated that... :)
"The man's wife has also tested positive for the virus today"
To be fair, the article in the SMH was a bit ambiguous.
Anyway, they've linked the case (man - and presumably his wife) to a returned traveller who was quarantined, then developed covid. The case is the B1.617.2 variant (originally found in India) but that is (yet?) to be classified as a "variant of concern", so the Premier won't lock down. This is rather dumb IMO - but there you go, Liberal state, business matters. "It's not yet proven" that this variant is a contributing cause of the disaster in India isn't very reassuring. It needs to be proven that it isn't - and as the mutations seem to indicate that it's more contagious and more likely to be an escape variant, caution is needed.
They've also found C19 traces in sewage from the inner west of Sydney, so if the man and his wife didn't poop there in their travels, there could be other CT case(s).
Anyway, Sydney's in a kind of lockdown level 1.5 (using our system).
