I guess we will never know for certain, but it would be interesting to know if any of today's large number of positive cases in NSW were present at a certain potential super-spreader even in Sydney on the weekend? Certainly there was no QR check-in codes for the event, and I think if people were present and later become symptomatic and test positive, they would likely be reluctant to fully disclose their activities related to such an event. I certainly hope this is not the case. If it is, then there are likely a lot of people in "denial" about symptoms and unwilling to be tested in case it jeopardises their belief.
