Diving on the great barrier reef a few years ago, a white tip reef shark swam right into my face full pelt. It was on a night dive and approached my buddy's light before seeing us, shitting itself and bolting, straight into me unfortunately!
Used to teach diving on the Yongala off townsville, which has a resident bull shark, i was gutted i never got to see it, but saw some meaty grey reek sharks and shovel nosed rays.
Completely agree id much rather come accross a shark 30 meters underwater than at the surface!
