Kingscote Jetty

Kingscote Jetty, Kangaroo Island, South Australia; Guide: Kangaroo Island Dive and Adventures (kangarooislanddiveandadventures.com.au); For a seriously off-the-beaten-track cold-water dive, look to South Australia. At Kingscote Jetty, keep a close eye on fluttering kelp fronds to find the endemic leafy sea dragon. “Without a guide, it can be hard to find them,” says Andrew Carney of Kangaroo Island Dive and Adventures. “Divers often mistake them for a piece of weed.” These seahorse cousins have leafy appendages that look exactly like their kelp backdrops.
