Locally transmitted Covid19 cases in NSW since the first local elimination, daily and 7-day average (data from http://covidlive.com.au ). Negative cases reflect reclassifications of false positives. For non-Australian readers, yes, the Y-axis is in actual numbers.

This really highlights how much better contained the December outbreaks (both Avalon and Berala strains) were than the July outbreak (Rydges strain), which is exactly what you'd expect from six months of intensive learning on the job.

Everyone was very freaked out by the Avalon 30 case day, but it turns out that a) testing for priority cases can be now done in a couple of hours, b) guest registers are digital and mostly accurate - so the rapid peak reflects the fact that you've found everyone in a day.

And again, for the indiscriminate lockdown fans: all currently known spreading events in the Berala cluster (the only one which is still showing new cases outside of isolation) are in venues that would have been open under lockdown or in private homes.
