Almost walked into this guy tonight. Sheesh! I’m not a big fan of spiders. At all. From what I can tell, though, he looks a lot like a Garden Orb Web Spider (Eriophora transmarina). Scratch that, I have no clue what this guy/gal is. I have seen far too many photos of spiders on google now, though. Sheesh!
Ask your Mother. As a former Web she should know.
