He Fenced Off a Dead Australian Farm and Removed Every Animal Inside — What Followed Was Impossible

In 1969, mathematician and conservationist John Wamsley purchased a degraded 14-hectare dairy farm in the Adelaide Hills of South Australia. His goal was to turn the damaged land into a safe haven for native Australian wildlife. Wamsley removed introduced predators and pests, including feral cats, foxes, and rabbits, and began restoring the native ecosystem. He surrounded the property with predator-proof fencing, planted approximately 100,000 trees and shrubs, and created water sources to support returning wildlife. The project became known as Warrawong Sanctuary, a pioneering conservation effort designed to give endangered Australian animals a chance to recover in a protected environment. What began as a neglected farm was transformed into a refuge for native species, demonstrating how damaged land can be restored through determined conservation work. This is the story of how one man turned a struggling Australian farm into a wildlife sanctuary.
