We've collected a wealth of data re NSW clusters, showing the effective whack-a-mole / suppression since mid 2020.
But the most interesting bits are the 'cluster trees'.
A few things they show... 1/6

'Cluster trees' are the way we refer to the meta-clusters, if you like, made up of sub-clusters and outbreaks across primary, secondary and tertiary locations, as well as household and social contacts linked to these.
Here is part of the Crossroads cluster tree.

And here is part of the Thai Rock (Wetherill Park) cluster tree.
In both, we can see the spike of transmissions from the primary location and their immediate households / social contacts, then the trickling outwards.

In contrast, the Sydney CBD cluster had highly dispersed spread extending to at least 24 transmission scenarios.
Most remote appeared to be contacts linked to tertiary location - 4 deg of separation. E.g. City Tattersalls gym > Bus X39 > Physiotherapy > related contacts.

Another neat thing about bringing the data together is you can compare unique transmission points across clusters, giving better perspective / context.
E.g. Potts Point cluster does not appear much larger than Berala but vast majority caught it directly at the Apollo.

Clusters are also tabled based on final count and initial location type.
