The Department of Environment and Heritage Protection is warning north Queensland residents to be on the lookout for crocodiles as temperatures soar.
The department says the current heatwave may force crocodiles into areas they are not normally found.
Department regional team leader Chris Pacey says warm temperatures, combined with croc breeding season, means the reptiles are far more active in local rivers and creeks.
"Those higher temperatures can potentially push crocodiles into those sort of temperature zones where they're not comfortable," he said.
"They're also more difficult to spot at this time of year because they're often in the water trying to cool off as well as looking for food."
He says it is important to ensure children are always supervised and nothing is left on the water's edge to entice a crocodile on shore.
"Places like boat ramps and other popular fishing spots, people leaving scraps behind, whether it's frames or bait that can attract crocodiles to the areas," he said.
"Crocs, for the most part, are lazy predators, so if they have the food presented to them they're going to start hanging around those areas."
