A Far North Queensland council is calling on the State Government to remove a population of saltwater crocodiles found living far from their natural habitat before they reproduce.
- Survey finds 23 saltwater crocodiles living in Lake Mitchell and Two Mile Creek waterways
- The area is not a traditional crocodile habitat
- Crocodiles may have escaped from nearby crocodile farm, several years ago
The Mareeba Shire Council commissioned two surveys of local waterways on the Atherton Tablelands, in the Cairns hinterland, 400 metres above sea level and 65 kilometres from the coastline.
More than 20 saltwater crocodiles were found living in the Lake Mitchell and Two Mile Creek waterways — in the Quaids Dam area near Mareeba — an area where crocodiles are not normally found.
It is not known exactly how the reptiles got into the area, but theories suggest they may have escaped from a nearby crocodile farm, several years ago.
Mareeba Mayor Angela Toppin said they commissioned the survey as a result of community fears that the crocodiles could travel into the Barron River, a popular swimming and recreational area.
“These crocodiles need to be removed. The State Government needs to move very fast on this.”
Spotlighting at night
The survey found no evidence of saltwater crocodiles in the Barron River, but rather, several small isolated pockets of freshwater crocodiles, who are naturally found in the area.
Brodie Moloney, from the Top End Crocodile Service, was commissioned by the council to conduct the survey, using a range of methods, including an aerial survey, spotlighting at night in kayaks, and walking along riverbanks.
He said there was a chance the saltwater crocodiles found in Lake Mitchell and Two Mile Creek would eventually make their way into the Barron River.
“They can get in there (Barron River), it’s possible, ” Mr Brodie said.
“Two Mile Creek floods very easily and a lot of those surrounding cane fields go under.”
