It wasn't complex.
The man from SA was tested returned to Melbourne on a Tuesday. H was aware of symptoms on sat and tested soon after limiting community spread. His own housmates did not even test positive to the kappa.
Then during Vics lockdown a person presented with delta, incredibly she had been to NSW but did not spread it there. Because Vic were already in lockdown with health measures in place there were fewer uncontrolled contacts.
Complex is the Sydney driver having covid and driving other people around before being detected. Complex from the beginning.
