Travelling up here and anywhere outback I am never without a strong Insect and Mosquito repellant. Most annoying are the flies during the heat of the day.. Spray the outside of your hat and the back of your shirt with a good dose of Insect repellant usually keeps them at bay.. but in the evening the mosquitos are the most annoying . The mosquitos though ,can carry life threatening viruses such as Dengue fever and encephylitis. So it pays to be careful. These viruses are really dangerous and is best to cover up in the evenings with loose fitting clothing..long sleeves and long pants..make sure that you apply a repellant to all exposed skin for best protection....Don't forget the tops of your ears!!!..
Katherine is located in the middle of the Northern Territory in what "aussies "call "outback" it gets really hot and humid out here. Make sure that when you are out and about here that you always carry a good supply of fresh bottled drinking water..Due to extreme heat and humidity it is easy to get dehydration...this can happen after physical activity by not replacing lost fluids..drink plenty of water out here especially when in the National Park. Always wear a hat.
Do not ever be blase about crocs and snakes when in the territory.
They are dangerous and can kill.
There are both salt water and fresh water crocs in the Katherine area - learn about the differences. Not that it means you can swim in "freshie"waters. Crocodiles can, and will, attack on land so learn about their habits before wandering into waterways, be it river, lagoon or coastal areas.
There are both harmful and harmless snakes in this area - it can be very hard to tell the difference so don't be smart and think you can pick up a snake.
There are great distances in the territory from clinic to hospital to hospital. The Flying Doctor does a wonderful job up here but please do not be silly and have the Flying Doc being called out because of a stupid prank.
It is not acceptable to go looking for aboriginal art in the park as this could lead to damage of the art and enviroment.The park rangers can show some examples -as seen in the photos i have provided.
Usually the only crocodiles are freshwater crocs, so no fear there. But do ask at the entrance before jumping in the water, sometimes (rarely) there have been saltwater crocdiles.
There are quite a few shady banks along the gorges but you can't go onshore on all of them all the time - sometimes the crocodiles are nesting.
It's easy to underestimate how much water you need when walking around in the local climate. Regardless of which time of year it might be, it can still be quite hot during the day. Most people carry some watre with them whether they're in town or out of town. It's a good habit to get into.
There are many small sandy beaches through the gorge that are well posted as crocodile nesting areas.As seen in this photo.
Do not stop there!
