I think the majority of people go with whatever the Government mandates to feel safe, the perception of safety - "they are keeping us safe." "It's for our own good."
The $11k fine for posting anti-lockdown online doesn't exist. It was proposed by the opposition party of the NSW government. I think it was intended as a swing at the ruling party ie for political purposes. It's akin to a little yappy dog.
Thanks for the update.
