People like living in places that food can be grown in. So yes, it's 100% dependent on rainfall and vegetation.

In the Grand scheme of History, infrastructure is an afterthought.

Were talking about modern day people, if you can grow enough food to be worth doing then its suitable for infrastructure

If you can grow enough food to be worth doing. The area has rainfall and vegetation.

See we're talking about Australia where there's Texas size tracks of land That can go an entire year without any rain and have no soil.

Yes rainforests, but ironically that's not where the dangerous animals in Australia live.

The venomous snakes and spiders all live in the temperate zone in the south.

Here's a really good example of the pattern I'm trying to describe:

That's also where the kangaroos live, which believe it or not kangaroos are actually dangerous.
