An order of magnitude higher and it'd be of similar magnitude to the entire USA. I tend to think of Australia as pretty similar (if literally polar opposite) to Canada. Similar population and standard of living on a similarly large but largely inhospitable landmass.
Australia is basically Hot Canada.
Seems related to the fact that you can draw a surprisingly-small circle over part of Asia and have more people inside the circle, than out. Human geography is very uneven.
Doesn't 80% of the world's population live within 100km of the sea as well. And I'd guess most of the remainder live close to major rivers and lakes.

Holy crap, Australia has approximately the same population as New York City. That's nearly an order of magnitude less than I would have guessed. I had no idea!
I'm pretty sure NYC has a population of like 7 or 8 million, about a third of Australias.
Lol and I think Sydney is getting “too busy”

Lots of things on Earth are unevenly distributed. Mineral deposits, water, fertile land, mild climates…
Quite probably only if we're ignoring the z-axis (depth), at least when talking over minerals. I think it will be a game-changer if a few km of rock won't be a hindrance anymore. If that ever comes, that is.
When does the mega sunspot or whatever hafta fire a large mass ejection at us, and how strong would it have to be, to cook most of humanity?
The sun fires multiple ejections a day big enough to cook us. They just all miss. It would be like you stepping outside and shooting a bullet in a random direction a few times a day, with Earth being a golf ball miles away. The golf ball would be destroyed by a bullet. But your odds of hitting it are very low. Of course, over time the odds become an inevitability.

If you want an idea of scale, there's a single cattle farm in Australia operated by less than a dozen people that is larger than Texas.

Why is this downvoted? Is it wrong? I do like it as an explanation!

I don't know that there has ever been a CME strong enough to cook all animals on the side of Earth facing the sun, though. The sun is pretty far away and Earth has a nice magnetosphere that is one of the reasons life exists in the first place. It protects us from stuff like this.
Incidentally, a CME cooking the entire Earth was the plot of a pretty terrible Nic Cage movie called Knowing a decade or so back.

Australia has almost everything wrong you can think of climate-wise: cold Antarctic currents hitting the west coast causing dry winds with little moisture, on the east coast there's a narrow strip between the coast and the long N-S mountains that gets moisture, but even then the mountains are barely high enough to trap winds and cause rainfall. The very north gets monsoons, the inland is a baking desert and only the…
Texas is rather larger than Anna Creek, at 676,587 km2 of land according to https://en.wikipedia.org/wiki/Texas .
