During the wet season there's no shortage of water, even on the roads. You then have to make a decision whether to cross through the water or not.
The best advice is DON'T! Although sometimes you have to.
Water crossings are dependent on a number of factors.
The vehicle you're in.
The depth of water to be crossed.
The speed of the flow of the water.
The nature of the ground surface under the water.
And not least of all, your ability or knowledge of making water crossings.
All these factors are extremely variable and probably no two crossings are the same.
You may not see one, but crocodiles sometimes get out onto the road near the South Alligator River. Getting out of the car for a close up photo might result in a great picture, but you might not be around to see the results.
Two types of crocodiles live in Kakadu - Freshwater and Saltwater (Estuarine).
Freshwater crocodiles usually don't attack unless they are bothered. But it is a good idea to just leave them alone.
Saltwater crocodiles are very aggressive and can kill people. DO NOT swim in any area where saltwater crocodiles can be a threat.
Most swimming areas are checked during dry season for crocodiles, but some manage to sneak in. So wherever you swim, you are doing it at your own risk. Pay attention to the posted signs.
I don't know how effective this is (and I would rather not know), but our guide told us that if a crocodile grabs hold of you, try to poke one of its eyes.
Don't strap any good camping gear on the top of the car because of the dust.
And definately don't wear your good clothes camping :o0
If you see a set of tracks like these look carefully around. You could be in for an invitation to dinner - you as the main course.
