The largest fringing reef, World Heritage marine parks, untouched coral atolls, top-rated dive wrecks and encounters with a staggering array of marine life await on Western Australia’s temperate and tropical coast. That's over 12,500 kilometres of snorkelling and diving experiences.

The coast between Rottnest Island (Wadjemup)'s Class A marine reserve and Ningaloo Reef (Nyinggulu) holds second place in the world for having the highest number of marine species. Here, you can meet rare Australian sea lions and friendly wild dolphins, snorkel with turtles, dugongs, reef sharks, graceful manta rays and the largest fish in the ocean, the gentle giant whale shark. And beyond Ningaloo Reef (Nyinggulu), experience every diver's dream on Rowley Shoals.
