I've lived the extremeness of both ends of the world; from downunder to way 'up' north, USA.
In Australia it can get so dang hot and humid you'll sweat like a hog all without tha' butt leaving the chair.
Having lived in Australia for decades I can tell you it's very refreshing to be where I am right now (Wi, US) yet I'm still not sure where I'd rather be;
Both offer the good, the bad and the ugly; in tropical humid regions you put up with lots of bugs, snakes, gators, flies and mosquitoes whereas in the far north where I am now all the little critters seem to be in a state of cryostasis.
