Guy Hull’s The Ferals That Ate Australia is an eye-opening and often infuriating exploration of Australia’s battle with invasive species. In his book, Hull dissects the disastrous environmental consequences of introducing non-native animals to Australia, none more emblematic of this folly than the cane toad.
Originally introduced in 1935 as a biological control for beetles threatening the sugarcane industry, the cane toad has become a poster child for poor ecological decision-making. Hull vividly recounts the hubris of scientists and agriculturalists who, in their short-sighted wisdom, imported 102 toads from Hawaii without adequately considering the potential risks. The assumption that these amphibians would obediently stay in cane fields and feast on pests is, as Hull outlines, laughably naïve.
Instead of solving the beetle problem, the cane toads became a far greater menace. With no natural predators in Australia and an ability to breed prolifically, their population exploded. Hull examines their devastating impact on native wildlife, from poisoning predators like quolls and goannas to outcompeting local species for resources. Their relentless march across the country has wreaked havoc on ecosystems and caused irreversible damage.
Hull’s critique of the people responsible for introducing cane toads is scathing - and deserved. He paints a picture of agricultural planners driven by profit and expediency, oblivious to the fragility of Australia’s unique ecosystems. The lack of scientific rigour and foresight in their decision-making feels, in hindsight, almost comically absurd if it weren’t so catastrophic.
The book also examines the broader lesson of the cane toad disaster: the dangerous arrogance of trying to 'fix' nature without understanding it. Hull uses the cane toad story as a cautionary tale, underscoring the importance of ecological balance and the devastating consequences of human meddling.
Hull writes with a mix of humour and indignation, making the book both accessible and engaging. While the tone is often biting - especially when criticising the absurdity of past decisions - it’s balanced by his deep knowledge and passion for Australia’s wildlife.
The Ferals That Ate Australia is recommended for anyone interested in conservation, environmental history, or simply shaking their head at one of the most avoidable ecological blunders in history. Hull’s work is a stark reminder of the long-lasting consequences of human recklessness and the ongoing fight to protect Australia’s unique biodiversity from the mistakes of the past.
