New research reveals that creating more fox-free sanctuaries through public-private partnerships could be crucial for protecting the vulnerable Parma wallaby, particularly in the wake of devastating bushfires that have threatened their survival along Australia’s Great Dividing Range.

The contrast couldn’t be more striking: while Parma wallabies face extinction threats in their native Australia, they’re thriving to the point of overabundance in predator-free New Zealand. This paradox lies at the heart of new research from The Australian National University (ANU) that examines the complex challenges facing this distinctive marsupial.
The study, co-authored by ANU Professor George Wilson and Samaa Kalsia from Australian Wildlife Services, highlights the devastating impact of predation on Parma wallaby populations. “An attempt to reintroduce a population near Robertson in New South Wales was unsuccessful, with foxes killing more than 40 Parma wallabies within three months,” Wilson notes in the paper.
The research reveals a critical gap between conservation aspirations and reality. While the New South Wales government’s Saving Our Species program outlines conservation strategies, the researchers argue these plans fall short of addressing the immediate need for predator-free sanctuaries. The success of existing protected areas, such as the private enclosure at Mount Wilson, demonstrates the potential of this approach.
The Black Summer bushfires have added urgency to the situation, likely decimating significant portions of the Parma wallaby population and their habitat along the Great Dividing Range in northern New South Wales. While the NSW National Parks and Wildlife Service is constructing an enclosure at Ngambaa Nature Reserve, the researchers emphasize that more facilities are needed.
Kalsia highlights a fundamental challenge: “A lot of the threats to Parma wallabies outlined by the New South Wales government is actually indicative of a lack of knowledge or an insufficient understanding about the animals’ habitat and food requirements and the extent of the impact of predation by foxes, among other concerns.”
