Yep, been to the reef twice and thankfully no sign of jellyfish.
And yes, I've taken a swim within the confines of the stinger net on the beaches just south of Palm Cove - Clifton Beach and Trinity Beach. I'm pretty sure the vinegar photo is from Clifton Beach.
Palm Cove is beautiful. Otherworldly, really. One of my favorite places on this planet.
Yeah, my son still is planning how to move there. I'll miss him a little.
