Greetings from Melbourne, Victoria, currently on stage 4 lockdown because enough people are selfish and don't care (unless threatened).
EDIT: (Leaving my original text unmodified above) Agree that this sounds crass, and probably not very cultivated by HN's standards, but it's from the point of view of extreme frustration with the situation - having done all the right things myself, only to see it undone by others who just don't care.
I did observe significant changes of behaviour after the fines started getting press coverage. I believe it is indeed incredibly hard to reach out and educate the masses, but when the health of our society depends very much on the last few %s doing the right thing, and this segment is so hard to get to, then drastic measures do have a play. It definitely ought to be backed up by other educational efforts though.
This crisis is making me think hard about where we draw the lines on individual freedom, when they can cause harm to others. Also, having said the above, a number of breachers were in the upper echelons of society financially wise - so it's definitely not a clear cut thing about who needs to start caring more.
