6/6 ... And here it is on log scale

The intervals are not very easy to see on this chart

But as an indicator, Bondi outbreak took about 5 days to double from 100 to 200. 5 days later, we're at 330. So doubling rate slowing.*

*Footnote - our covid literacy is getting better all the time, so we understand these are fairly crude indicators, and the stories and factors behind these numbers are just as important
