Here’s a guide to the wildlife you might spot in and around Derby, and the best places to experience it up close.

1. Saltwater Crocodiles: Kings of the Kimberley

The saltwater crocodile, or "saltie," is one of the Kimberley’s most famous residents and is commonly found in the waters around Derby, particularly in King Sound and the tidal creeks. These ancient reptiles can grow up to seven meters long and are known for their power and stealth in the water. While they’re fascinating to observe from a safe distance, it’s important to always exercise caution when near any water in Derby, as saltwater crocodiles are highly territorial.

One of the best ways to safely observe these magnificent creatures is on a guided river cruise or by visiting the tidal mudflats at low tide, where you might see crocs basking in the sun or swimming lazily through the water. Many local tours focus on crocodile-spotting, providing insight into their behavior and biology while offering plenty of photo opportunities.

Good to know: Always follow safety guidelines when near water, as saltwater crocodiles can be dangerous. Stick to designated viewing areas or guided tours for the safest encounters.
