PFDs are not legally required for kitesurfing or windsurfing when less than 400 meters from shore in NSW. Still a good precaution though. You forget it's on with the good newer ones.
However, if on your own need to wear.
It's ok to swim out to a moored boat without a life jacket but if alone in a dingy one must wear a life Jacket.
I find it hard swimming to our boat with a backpack on full of essentials.
