An underwater encounter with a whale sharks is an unforgettable, once-in-a-lifetime experience.

Drawn by the annual spawning of more than 200 species of coral, the mysterious whale shark calls World Heritage–listed Ningaloo Reef (Nyinggulu) home between March and July each year. These gentle giants of the sea grow to 16 metres long and weigh around 30 tonnes, but they remain effortlessly elegant as they cruise along the reef, feasting on fattened krill.
