Native to Asia from Pakistan to Indonesia, the Asian black spined toad looks similar to the cane toad. The two species are closely related and share many biological attributes.
The Asian black spined toad is an invasive species that has naturalised in many regions of the world, including in Indonesia outside of its native range, on the Andaman and Nicobar Islands in the Indian Ocean, and in New Guinea and East Timor. It has not yet been recorded in Queensland, but its ability to hitchhike on cargo means it is likely to arrive here at some point. If naturalised in Australia, the Asian black spined toad is likely to have impacts comparable to those of the cane toad.
You must not keep, feed, move, give away, sell or release into the environment. Penalties may apply.
You must report all sightings to Biosecurity Queensland within 24 hours.
