Rabbit cull transforms Australian island into haven for endangered petrels
The eradication of rabbits from Cabbage Tree Island in 1997 proved transformative for Australia's Gould's petrel population, which surged to over 800 breeding pairs within three years. The conservation success has prompted expansion of breeding programmes to additional islands.

A landmark wildlife management intervention on Cabbage Tree Island off the Australian coast demonstrated the dramatic impact of habitat restoration on endangered species recovery. Following the elimination of rabbits in 1997, conservationists documented a remarkable resurgence in the Gould's petrel population, a seabird species that had faced severe breeding difficulties due to rabbit-related habitat degradation.
By 2000, just three years after the rabbit eradication programme concluded, the island supported approximately 800 breeding pairs of the petrels. The population growth exceeded expectations, with annual breeding producing more than 400 chicks. The recovery underscored how invasive species management could directly reverse population declines in threatened wildlife.
Recognising the success of the Cabbage Tree Island restoration, conservation authorities moved to establish a second breeding colony on Boondelbah Island. This expansion strategy aimed to reduce the species' vulnerability to island-specific environmental shocks and genetic bottlenecks associated with small, isolated populations.
The initiative highlighted the interconnected nature of ecosystem health and species recovery, demonstrating that targeted removal of invasive predators could yield substantial benefits for native fauna. Ongoing protective measures remain essential to sustaining the petrel populations as conservation efforts continue across the region's islands.
