Australia has some of the most deadly and amazing creatures on the planet and none more iconic than the crocodile. Of all the waterways in the country the Adelaide River in the Northern Territory is the most crocodile infested. Famous for its saltwater crocodiles this is the place tourists and wildlife enthusiasts come to see these apex predators in action.
Let’s dive into what makes the Adelaide River the crocodile hot spot, the types of crocodiles that live here and how you can experience it safely.

The Adelaide River: Croc Country’s Crown Jewel
The Adelaide River stretches 238km through lush country, past Kakadu National Park and into the Timor Sea. This is crocodile country, with one of the highest crocodile populations in Northern Australia. You can often see massive crocodiles, including ones over 4m long, basking on muddy banks or lurking in shallow water.
Why is the Adelaide River so infested?
- Perfect Habitat: Tidal waters, deeper water and brown water = crocodiles and their prey.
- Plenty of Food: Barramundi fishing and other aquatic life means there’s a food bonanza for these old reptiles.
- Crocodile Management Success: Wildlife rangers and organisations like Parks Australia have helped the Australian saltwater crocodile population recover since hunting was banned in the 1970s.

Saltwater Crocodiles: The Top Predator of the Adelaide River
The saltwater crocodile (Crocodylus porosus) or estuarine crocodile is the king of the Adelaide River. The largest living reptile, males can grow up to 6m and weigh over 1,000kg. These aggressive reptiles are ambush predators and can launch themselves out of the water with incredible speed.

Freshwater Crocodiles
Unlike their bigger saltwater cousins, freshwater crocs are smaller and less aggressive. They live in nearby waterways but are rarely seen in the tidal waters of the Adelaide River which is the domain of the more aggressive saltwater species.
Crocodile Density and Sightings
The saltwater crocodile density in the Adelaide River is incredible with estimates of 2 crocodiles per km in some areas. That’s why it’s one of the best places for Jumping Crocodile tour, attracting visitors from Darwin City and beyond.
