Yes good point - but......Florida deployed basically no effort trying to control anything covid related whatsoever, they allowed huge mass gatherings of strangers and also entered their summer with case numbers that would make any state of Australia lock down for 20 years
Also if you’ve been to Florida you will know a lot of them hide indoors, together with aircon, especially the older folk and it’s a very old state. Australia is much more outdoorsy, despite the heat.
Summer is going to help Australia big time I feel but only because we are in a good position to begin with and ongoing controls.
