Crocodiles are potentially dangerous. Never take unnecessary risks in a crocodile habitat. You are responsible for your own safety, so please follow these guidelines and be croc wise in croc country.
• Obey crocodile warning signs – they are there for your safety and protection.
• Never swim in water where crocodiles may live even if there is no warning sign present.
• When fishing, always stand a few metres back from the water’s edge and never stand on logs or branches overhanging the water.
• Never clean fish or discard fish scraps near the water’s edge, around campsites or at boat ramps.
• Stay well back from any crocodile slide marks. Crocodiles may be close by and may approach people and boats.
• Never dangle your arms or legs over the side of a boat. If you fall out of a boat, get out of the water as quickly as possible.
• Never provoke, harass or interfere with crocodiles, even small ones.
• Never feed crocodiles – it is illegal and dangerous.
• Camp at least 2m above the high water mark and at least 50m from the water’s edge. Avoid places where native animals and domestic stock drink.
• Never leave food scraps, fish frames or bait at your campsite. Always check that previous campers have not left these behind.
• Never prepare food, wash dishes or pursue any other activities near the water’s edge or adjacent sloping banks.
• Be more aware of crocodiles at night and during the breeding season, September to April.
