You'll find plenty of safe places to swim in the Northern Territory, as long as you check the safety signs and exercise caution. Check for warnings about the presence of saltwater crocodiles and box jellyfish (stingers), and if in doubt, stay out of the water. Do not jump or dive into shallow water or into waterholes, rivers, or creeks, as submerged rocks and logs can cause serious injury. And if you're going to the beach, choose a beach patrolled by lifesavers and make sure you swim between the red and yellow flags, wear protective clothing (stinger suits) and carry vinegar in case of jellyfish stings.
Boating and fishing safety
Boating and fishing is an integral part of local life – keep safe by familiarising yourself with local boating regulations and marine safety, and always tell someone where you're going and when you expect to return.
Be wary of saltwater crocodiles and box jellyfish. Do not clean fish, or dispose of carcasses in or near the water, or near boat ramps, and never dangle your limbs or wash your hands over the side of the boat. If possible, avoid standing in the water when launching and recovering your boat.
Be prepared for an emergency: carry an EPIRB or satellite phone, extra fuel, tools, basic spare parts, a first aid kit, life jackets and sufficient food and water for those on board. Always stay with your vehicle or boat if something goes wrong.
As with any outdoor activity, if you're in or on the water, make sure you protect yourself again sun exposure with a hat, sunglasses and sunscreen.
