Multiple sightings of a large crocodile at a popular Queensland tourist beach has prompted a warning for locals and holiday-goers.
The Department of Environment and Science received four separate reports this week at different locations across Airlie Beach of a crocodile swimming close to enclosures, marinas and the popular foreshore.
Another sighting report was received on Friday of a large crocodile in the Shute Harbour area.
Wildlife officers are carrying out land and vessel surveys to determine if the crocodile is still in the area and have installed recent crocodile warning signs.
Anyone who sees a crocodile should report it immediately to DES through the QWildlife app or by phoning the department on 1300 130 372.
Passengers on a river cruise in the Northern Territory could hardly believe their eyes when six-metre crocodile, known as "Dominator", began devouring a juvenile croc within metres of their boat.
Tour operators from The Croc Bus told 9News.com.au, "If he keeps gobbling up two-metre crocs like the one here, he could eventually grow to being one of the biggest crocodiles in the world."
Jake, a representative for The Croc Bus said: "It's a kind of population control."
"This river is infested with crocs every hundred metres, and we're just at the end of the breeding season."
Jake revealed that after four to eight weeks, crocodiles lose their maternal instinct "and in this case, this young croc was seen as prey".
The six-metre saltwater crocodile is estimated to be over 80 years old.
One NSW resident had the shock of their lives on Sunday afternoon after walking outside their home and stumbling on a freshwater crocodile in their own backyard.
Normally found some some 2500 kilometres north in Queensland, this little critter - about a metre long - was found nestled comfortably down the side of a property on the Central Coast.
The mature female, believed to be between eight to 10 years old, is thought to have been kept, possibly illegally, as a pet.
"I was incredibly shocked when we received the call – freshwater crocodiles are usually found about 2500km north of where we are here on the Central Coast," veteran croc keeper Billy Collett with the Australian Reptile Park said.
"I honestly had to see it with my own eyes before I could believe it."
Collett said while freshwater crocs are less aggressive than their saltwater relatives, it's still not a great idea to approach them.
"We're grateful to the homeowner for alerting us to the presence of the crocodile," Collett said.
"Freshwater crocodiles may not be as dangerous as saltwater crocodiles, but they are still wild animals and can be unpredictable.
"It's always best to leave them to the experts."

Fitzroy Crossing, Western Australia
A Western Australian woman spotted this big crocodile early in the morning in the remote town of Fitzroy Crossing.
The reptile had been washed up during recent flooding and was stranded on a run-off drain.
Authorities were called and police tried to wrangle the croc with anything they could find.
Armed with a wet towel about half the size of the croc, one officer attempted to cover its head - but he had little luck.
The crocodile snapped it up within seconds and whipped it around in the air, as the police officer slowly backed away.
The crocodile was eventually tranquilised by a local wildlife expert and then safely returned to the river.
Police said without the expert's assistance, "there would have been no way to safely relocate the crocodile without officers or the crocodile itself being harmed".
