There’s another side to Western Australia’s favourite island retreat, Rottnest, many of us, haven’t seen – and that is because it’s well-hidden. Deep below its sarongs of beautiful blue waters are a series of underwater caverns that are teeming with vivid marine life – and it’s pretty special.

Rottnest Island is a playground for avid divers and ocean lovers. Its thoroughfares, galleria of corals, caverns, gentle currents, and colourful residents make it an exciting place for a deep-sea safari.
