Cane toads

Cane toads were introduced to Queensland from South America in 1935, in an unsuccessful attempt to control cane beetles, a pest of the sugar cane industry. Having no natural enemies, the toads spread west into the Northern Territory and south into New South Wales. They are now a major threat to native animals on the far north coast of NSW.

How far have they spread? Why are they a problem?
See a map showing cane toad populations in NSW. Find out why their poisonous nature and voracious appetite are a threat to native animals and pets alike.

Cane toad - key threatening process listing
See the NSW Scientific Committee's reasons for declaring this 'key threatening process' in NSW.

Identifying a cane toad
See what they look like, listen to their croak, then take a test to make sure you don't confuse a cane toad with a native frog.

black-spined toad was found in early 2015 in the north-east of Sydney. Intense searches were conducted around the area but no other toads were found. This species is like the cane toad in many ways, and could potentially cause similar problems if breeding populations were to become established.
