Exotic toad identification chnew eartharacteristics Cane toad Reports of exotic toads are critical to Agriculture Victoria's efforts to protect Victoria from the establishment of exotic toads.Īll sightings of exotic toads must be reported to Agriculture Victoria immediately. If still in doubt, email photographs to Agriculture Victoria at or contact the customer service centre on 136 186, with details of the animal, and a member of staff will contact you. Many of the cane toad reports Agriculture Victoria receives are actually the native eastern banjo frog, also known as the pobblebonk ( Limnodynastes dumerilii).īefore making a report of an exotic toad, use this information to check the features of the specimen you have sighted and compare the prominent identification characteristics that set native frogs apart from exotic toads.
