No. It’s too short and too late.
I’m in Melbourne we went I to a much tougher lockdown (that got even more restricted at the stat of July when we had about 200 cases. About a month into lockdown we hit 700 cases because the the infection was still spreading due to the high numbers.
Schools were closed, we weren’t allowed to go more than 5km from our house unless we had a permit and there was a curfew so no travel between 8pm and 5am unless permitted. Mask wearing outside your house was compulsory.
Restrictions started to ease about a month ago, in stages... right now shops and cafes are open (with capacity restrictions) schools are open and curfew has been lifted and you can now travel 25km from your house.
Still limits of gathering size, you can only have visitors from one household a day, etc.
Huge effort on testing and most people got results in under 24 hours.
We now have one or two cases a day. So it took us four months with a much lower base, less concentrated population and much stricter rules.
Nobody liked it, but it was largely accepted and complied with.
I don’t think a month will do anything at all... in fact the infection rates will likely be higher (due to transmission etc) and that will just further upset people.
Short, sharp lockdowns aren’t effective when the case load is so high. I’m sorry, I wish it were better
