Crocodiles in Kakadu: What You Need to Know
1. Saltwater Crocodiles vs Freshwater Crocodiles
Kakadu has two species of reptiles—the saltwater croc (also known as the estuarine crocodile) and the freshwater crocodile.
Saltwater Crocodiles (“Salties”)
- The biggest reptiles on Earth, up to 6 meters long.
- Aggressive, territorial and responsible for crocodile attacks.
- Found in coastal waters, freshwater rivers, billabongs and other bodies of water.
- Can live in saltwater and freshwater habitats.
Freshwater Crocodiles (“Freshies”)
- Generally shy and not dangerous unless provoked.
- Smaller than salts, up to 3 meters long.
- Found in freshwater rivers and billabongs.
- Unlike their bigger relatives, they don’t attack humans.
2. Where Do Crocodiles Live in Kakadu?
Crocodiles can be found in all major water bodies in Kakadu, including:
- Yellow Water Billabong – A popular spot for boat cruises, with some of the best crocodile views and water bird life.
- Mary River – Has one of the biggest saltwater crocodile populations in Australia.
- Adelaide River – Home to the famous jumping crocodile cruises, where you can see these amazing creatures in action.* Arnhem Land & East Arnhem – Culturally significant and home to many wild crocodiles and rock art, like at Ubirr Rock.
They can also be in unexpected places as water levels rise and fall during the wet and dry seasons.
How Deadly Are Crocodiles?
Crocodile waters in Kakadu can be deadly if you ignore basic rules. The 1970s crocodile cull allowed the Australian crocodile population to grow, so now there are more aggressive saltwater crocodiles.
While Parks Australia does manage crocodiles to keep you safe, it’s only a matter of time before someone gets hurt if you ignore signs.

Crocodile Attacks: A Real Thing
Crocodile attacks are rare but happen when people ignore signs or swim in crocodile country. Recent incidents prove pay attention to signs is key.
According to crocodile managers, most attacks happen when:
- In the wet season, when crocodiles move into new areas.
- Late afternoon or at night, when they are most active.
- When people get too close to the water’s edge, unaware of these snakes in the grass.
Stay Safe Around Crocodiles
If you’re visiting Kakadu, be Croc-wise by following these rules:
Follow all the signs – Never swim in a body of water unless Parks Australia has said it’s okay.
Stay at least 5 meters from the water’s edge – Saltwater crocs are snakes in the grass and can strike in fast currents.
Don’t enter crocodile waters – If a body of water is not signed, assume it’s not safe.
Don’t do late afternoon & nighttime activities – Crocodiles are most active after dark.
Don’t feed wild crocodiles – This is illegal and makes them think humans = food.
Camp at least 50 meters from water bodies – Even at night, wild animals like feral animals, venomous snakes and crocodiles can wander into campsites.
Be extra careful in the wet season – Rising water levels means crocodiles can be in unexpected places.
