The time to lock down is when there is one case - that’s how you get back to zero. That’s what NZ is doing and it’s a proven method of eliminating COVID. Waiting until you have thousands of cases makes lockdowns less likely to actually succeed.
The other video you posted is an inspection of someone who is quarantined - it’s not illegal to get fresh air. If you’re subject to quarantine it means you tested positive for Covid or are a close contact of someone who did, and that means you’re required to stay at home to not infect other people. That’s a reasonable thing to do even in America; it’s just taken more seriously in Australia on account of the relatively low rate of infection as compared to the US.
WE WILL NEVER be back to ZERO COVID.It will always be here in the environment. Here, there, everywhere. In Russia, China, America, and Austealia.
Everywhere.
The Aussies have gone stark raving nuts in their attempts to achieve the
IMPOSSIBLE. No talking to neighbors .... masks on
while drinking 
(how does
that work? ?) and using the military to enforce lockdown.
It would almost be understandable if this
was THE ANDROMEDA STRAIN, a fictional alien microscopic bug brought to earth in a satellite in a novel by Michael Crighten that was made into a movie in 1971. That was science fiction.
What one might not remember from the movie, (if you ever did even watch it) is in the few minutes between initial infection with Andromeda and
certain death, it drove the afflicted insane.
As I said, that was science fiction. It wasn't real. Thank God.
Covid 19
is real, of course, but nowhere near as fatal, even the D strain. But it is sorta like Crighton's mythical microscopic monster in one way:
IT IS DRIVING EVERYONE INSANE ......
