I think much of the Sydney (wont say NSW... Im not in lockdown!) issue is complacency from having zero COVID for so long. Now a lockdown is in place, lots of people are just looking to be doing the lockdown while actually ignoring it. Ive seen friends post on facebook about going out for exercise (allowed) and just happen to run into friends and then there is 8 of them in a picture, no masks, all posing for a photo.
The state govt's instructions have been poor, lots of "do the right thing", "only essential" while giving no clear guidance. Some people are unsure, others just twisting it and pushing the boundaries. And now they wonder why its not getting better!
This lockdown will be months if people dont actually stay the fuck at home
