You know that it's summer in Australia now, right?
Yep, and Melbourne had it's "second wave" in the middle of winter. Locked down and got it under control. We've had the opportunity for things to go pear shaped, but due to decisive action, an educated and thinking public and fairly strict enforcement we've got no community transmission. The only issue we have is that our methods of isolating people returning to the country are proving to be somewhat inadequate with people like cleaners picking up the virus from the isolation facilities (Hotels). These issues are being improved and it looks like we are going to continue to be virus free.
Meanwhile in the Northern Hemisphere, the winter surges correlate with latitude, after a quiet summer. There’s a pretty obvious pattern: https://www.nature.com/articles/s41598-021-81419-w
