NSW removed all restrictions right before Omicron. They had zero of these so called “extremely strict rules” in place for the last month or so. The premier only changed tact when it became obvious that hospitals would be overwhelmed (back to day one of the pandemic).

We don't have any restrictions now. We went from 100 to 0 and its spreading. I don't think there was even any density rules in my state, the nightclubs were packed on the 31st. Everyone I know who went clubbing on the 31st did end up with covid as well.

When Australia had strict rules and measures, it did not. Since removing these rules, it has.

Draw your own conclusions from that however you like.
