Montgomery Reef sits in the Kimberley region of Western Australia and is one of those places that feels genuinely wild. The waters are shallow, no deeper than 10 metres, which makes it accessible for beginners, but the currents here are extreme and must be taken seriously. Visibility varies considerably depending on conditions, so you cannot always count on clear water. What you can count on is extraordinary wildlife. Sea turtles, dugongs, manta rays, dolphins, and humpback whales all frequent this reef. Blacktip reef sharks, sea snakes, and octopuses are also present. Saltwater crocodiles have been recorded in this area, so stay alert and always follow your guide's instructions.

Always dive or snorkel with an experienced local operator who knows the tidal windows, as the extreme currents dictate everything about when and where you can safely enter the water. The best months run from March through to November, when conditions are generally more manageable.
Access is by multi-day cruise boat or scenic flight/helicopter from Broome or Kununurra. The reef is located approximately 20km offshore.
Snorkelling is not permitted in the Kimberley region, including Montgomery Reef, due to the presence of saltwater crocodiles. The tidal currents are extremely powerful and dangerous.
