Some interesting stats regarding population density. The whole thesis is available at https://apo.org.au/sites/default/fil...o-nid63334.pdf.
Attachment 172987
There was an article the other day where 70% of spread in Sydney is within family groups, its easy to blame that on people visiting against regulations but I can't imagine how a family of 5 living in a 3 bedroom unit could possibly not get Delta if one family member was a nurse, a bus driver or any other essential worker and brought it home.
NSW COVID: 70 per cent of Sydney cases from household transmissions
The media focusses on the breaches and I'm sure there is some level of non compliance but I fear that the transmission in densly populated areas is probably no more controllable than is currently being achieved.
