What's going to bite me up there? Stingers / Crocs / Bull Sharks / Sand Flies?
I usually ride in boardies and a sleeveless 1mm Synchro vest, not sure if that is NQ friendly??
Don't go out in boardies. Stinger suit is a must mate. You just don't know (or see) what's in the water. It's the time of year and last thing you want is people pouring vinegar all over you to ease the stings. They bloody hurt! Trust me. The crocs and sharks are the least of your worries.
You can get some really funky stinger suits these days with patterns, etc... I once saw a guy in a spiderman stinger suit. It was awesome!
