Cane Toads have been present in Australia for nearly seventy years. They were introduced to Australia in 1935, when approximately 100 individuals were imported from Hawaii in 1935. Around 3000 young toads were released at Gordonvale near Cairns, North Queensland, to control the sugar cane pests, French's Cane Beetle, and the Greyback Cane Beetle,Dermolepida albohirtum, whose larvae eat the roots of sugar cane and kill or stunt the plants. Cane Toads proved to be unsuccessful in controlling cane beetles.
Since its introduction to Australia, the Cane Toad has spread south and west across the continent and now occurs in Queensland, Northern Territory and New South Wales. From their introductory site near Cairns, the Cane Toad has spread throughout Queensland, being recorded in Brisbane in the 1940s, and was considered to occupy approximately 50% of the State by the late 1990s (Sutherst et al. 1995).
