A 4.5metre iconic crocodile has been caught by wildlife officers north of Port Douglas after it was found swimming around with a crab pot stuck on its head.

Crocodiles longer than four metres are granted icon status in Queensland and can only be relocated to a registered farm or zoo that agrees to use it for educational purposes.

The state government is working in partnership with traditional owners to select a suitable facility to house the crocodile which is currently being held at a secure wildlife facility in Cairns.
