Has not the area you live in had 31 or so cases of the virus according to the stats that I have seen?
If you look at the % w.r.t. to the population densities of the areas in Vic, the Yarra Ranges area is probably just as high in the probability stakes as the Greater Melbourne area for cases of the virus because the yuppies also live amongst you who come up to their weekenders to get out of the big city.
Shalom.
They are not supposed to go their weekenders at the moment, which is another reason why some have been debating the Upper Yarra Valley should be out of the lockdown area, so the day trippers cannot come this way. And FYI yarra ranges has about 5 cases, but I believe most of those are on the city side of the Yarra Ranges, the population density on this side, the rural side is not high at all, the towns on this side have small populations.
