The ‘exact’ same thing? You mean a lockdown of the entirety of Sydney for a handful of cases? No, it didn’t. We did lockdown about 300K people for a super spreader event that seeded 30 people on one day though. Meanwhile the rest of Sydney was pretty sensible and got on with life.
Sydney was declared a hotspot and tourism came to a standstill from Christmas for a month, lockdown was over early to facilitate the holiday season but the damage was done. Just like the current Queensland situation.
