But population density in Sweden is 24p/km^2 while Australia has 3.3people/km^2.
Scandinavian countries are at least known to follow rules quite well as the trust for the gov is high.
They do had social distancing rules for example. Closed some school levels and forbid mass events.
Sweden also had one of the highest death rates at the beginning of COVID.
I haven't followed Australia to more detail though.
Edit: Scandinavian countries are also known for their really good internet (remote work)
Rules in Sweden were no nursing homes visits and no gathering above 50 people.
Look at youtube videos of social distance in Swedish metro during covid, hint there were no distancing.
Average age person who died with covid was 84 years old. Most of these deaths were in nursing homes, which once government realized it, visits were banned.

But I'm stating that this simplification in the earlier comment is not as simple.
Independent of this, it doesn't matter as captain hindsight didn't exist in the beginning of all of this.
If a peer reviewed study comes to the conclusion that a lockdown was a shitty idea it doesn't make it a bad decision.
Australia has 25 Million people.
The Netherlands for example had a much more open COVID strategy than Germany but culture wise there were much less weird / crazy people spewing miss information than what happens in Germany.
