Where did you find numbers that show Australia as bad as Sweden?
I understood Sweden's numbers were bad and Australia's were much better.


So I found this site with numbers from around the world and pulled numbers per 1Million population for a few countries.

Think these are correct as I may have switched a line as I read them.
Lots more countries listed if you are interested in another 

https://www.worldometers.info/coronavirus/
  
                 Cases.     Deaths 

US 76,279 1,273
Canada 19,413    496
Sweden 53,991 1,086  
Australia  1,120      35


And checking that my memory was correct about Australia locking down I found this article which also mentions China

.https://globalnews.ca/news/7347955/australia-coronavirus-lockdown-canada/

And it calls Victria state a 'severe' lockdown but I think it also stopped the spread 
That was September and the Lockdown had been in effect since July.
It says they had 11 new cases a day then compared with over 670 a day before

The epidemiologist that they quote  says it shows how targeted lockdowns can stop the virus

Victoria state lockdown rules include 

.Some of the measures include:

• You cannot leave your home unless it’s for exercising, caregiving, working or buying essential supplies. If you do leave, you must stay within 5 km of home
• Masks have to be worn outside
• Schools changed to remote learning
• Childcare centres are closed
• You cannot have visitors or go to another person’s house unless it is for the purpose of giving or receiving care
• You can meet one other person outdoors for a maximum of two hours
• There is a curfew between 9 p.m. and 5 a.m. (previously 8 p.m. to 5 a.m.) The onset of the curfew was adjusted to one hour later as spring approaches in the southern hemisphere and daylight hours will begin getting longer.
• There is a ban on weddings
• Restaurants and cafes will only be open for takeaway and delivery
