Souther hemisphere dwellers

I’m procrastinating writing a book of fiction based on questionable fact and it occurred to me that the detail of magic things being slightly to completely different in the Southern Hemisphere could be an important one and one appreciated to those who pick up on such details.

Being Norther hemisphere myself, I know the constellations are different but that’s kinda it. So does it make any kind of difference or is that mostly if you are astrological/seasonally based and what if any are any differences? Or things you would like acknowledged more of being different in the southern hemisphere.

Cuz it’s a made up world. I can and have and will do just about anything so long as I can wrap my little brain around it to make it cannon.
