The decision was made in Australia 12 months ago that they didn't want to risk the virus running around in the community like they did in some other countries and that they'd much rather shut down all 'hazardous' activities until they knew it was no longer around. We didn't have recurrent events like they did in Europe and the United States - with the notable exception of Victoria.You haven't had recurrent outbreaks because the virus was removed from the greater population through a series of heavy restrictions in April and May. Since then access into the country has been heavily restricted and requires everyone to go through a 2 week quarantine.
Strange because the UK pursued a really harsh lockdown policy and yet they've had this recent one over Xmas - are environmental (weather) factors a factor? There's a lot about this thing that we still don't know.
As I've also said in the past, we can't predict how the virus would have behaved in the open community here in Australia because it wasn't allowed to run rampant - all in the ether.
You are not currently living in the real world of freedom of travel you are living in an OPEN JAIL Don, HELLO!
The UK has freedom of travel, yes their higher density population didn't help. Ireland had similar issues. Colder weather keeps people together in doors. Doesn't help.
We saw how fast the bug spread during March /April in Australia, hardly the coldest time of year.
Prediction is not precise but its certainly ball park, there is only one expected outcome if the walls a let now, +20,000 dead by Xmas Don.
