If you are bringing your boat make sure the trailer tyres and bearings are in top condition before you leave. They literally fall apart. However the best fishing spots have excellent sealed-road access. Do not be put off visiting the Northern Territory during the wet season because of horror stories you may have heard about the heat and the rain. During the Wet the Northern Territory turns green and spectacular waterfalls flow hard.
Rain actually cools the weather down.
This is a great time to see and fish the Top End, except when the rivers are in full flood. The late wet season is the best time of all. Organise a trip with a charter for best results. The dangers of becoming bogged or lost in an isolated place must be kept in mind during the Wet, and you should plan accordingly if you plan on going alone. Always carry vehicle recovery gear when travelling off the beaten track, or travel with another vehicle.
