Wildlife officers from the Department of Environment and Science (DES) have removed a 4.2 metre crocodile following investigations into an attack at Ayton on Wednesday.
The crocodile was targeted for removal after it lunged at a man and his dog when they attempted to go swimming at the Bloomfield boat ramp about 5.30pm.
The man sustained lower leg injuries and the dog did not survive.
DES worked with Wujal Wujal Aboriginal Shire Council, Jabalbina Aboriginal Corporation and the Queensland Police Service as part of the operation.
The injured man has declined to speak to DES about the incident.
Overnight, wildlife officers from Cairns conducted a spotlighting survey of the river and located the crocodile about 200 metres from where the attack occurred. The crocodile was then humanely euthanised.
DES will liaise with Traditional Owners of the area regarding the appropriate disposal of the animal's remains.
Manager of Northern Wildlife Operations Michael Joyce said the Department's key priority was public safety, and the euthanasia of such a large old crocodile in its natural habitat was unfortunately unavoidable.
"It's important for communities in Croc Country to feel safe and for problem crocodiles to be dealt with appropriately," Mr Joyce said.
"Remember, warning signs are not there as decoration and swimming in Croc Country is a choice."
The Bloomfield River is well known Croc Country and people should always be Crocwise in that area. In particular:
- Expect crocodiles in ALL waterways even if there is no warning sign
- Obey all warning signs – they are there to keep you safe
- Be aware crocs also swim in the ocean and be extra cautious around water at night
- Stay well away from croc traps – that includes fishing and boating
- The smaller the vessel the greater the risk, so avoid using canoes and kayaks
- Stand back from the water's edge when fishing and don't wade in to retrieve a lure
- Camp at least 50 metres from the edge of the water
- Never leave food, fish scraps or bait near water, camp site or boat ramp
- Never provoke, harass or feed crocs
- Always supervise children near the water and keep pets on a lead.
