Toads most feral: what can Australia do?

Cane toads (Rhinella marina) are an invasive species introduced to Australia in 1935 to control agricultural pests. The species spread rapidly and now poses a significant ecological threat due to its toxic defences, which harm native predators. Their presence has led to widespread disruption of ecosystems across northern Australia.Guest: Professor Rick Shine, School of Natural Sciences at Macquarie University and author of Cane Toad Wars, published by University of California Press.Producer: Ali Benton
