1907: In 1859, Thomas Austin released two dozen rabbits on his farm near Geelong in eastern Australia. “A few rabbits could do little harm and might provide a touch of home, in addition to a spot of hunting,” he suggested. Austin’s “few rabbits” quickly multiplied to become millions, which destroyed crops and pasture and contributed to the extinction or major decline of several native animal and plant species.
Hunting, trapping and poisoning failed to contain the pests. Western Australia constructed 3,200 kilometres of wire mesh barriers – the Nos. 1, 2 and 3 Rabbit Proof Fences – but by the time they were completed in 1907, rabbits had already got round, over, under or through them.
