Is this the 1st outbreak in Sydney in that SW suburbs area (Fairfields / Canterbury-Bankstown / Liverpool area)?
Was thinking about this today, where people were asking, why have VIC always struggled with outbreaks and its been hard to answer. Maybe it really does come down to luck. Every outbreak we have had in VIC has originated in the Northern suburbs, where the population tends to move between properties far more, live in multi age home settings and work in lower paid employment (remember all the meat processing facilities etc that were mentioned in last years outbreak).
The current outbreak has happened in a similar economic / social area as our outbreak last year, much more so than the Northern beaches outbreak that was controlled (ie. more people can work from home, lower numbers of people per home etc).
So I'm hypothesizing here, but was Gladys just lucky last year and earlier this in terms of the locality that the outbreaks have occurred in in Sydney compared to Melbourne?
