She is starting to do now what she should have done 6 weeks ago.What are the main issues? A quick look on twitter and some are suggesting an even harsher lockdown. The current measures look pretty harsh.
She has spent the last year slamming other states for locking down when they have 2 or 3 cases, so as soon as NSW got some cases, she avoided lockdowns and basically just asked people nicely if they wouldn't mind social distancing, especially since it started in the more affluent Eastern suburbs. Of course it got out of hand, over 100 new cases every day for the past couple of weeks, so she is starting to do lockdown properly now.
If she had not been so stubborn and followed what Vic and WA do at the very start, they would have been out of lockdown 3 weeks ago
