WildArk has partnered with Aussie Ark, Re:wild and the Australian Reptile Park to rewild a 1500-hectare bush property in rural NSW, Australia. This is WildArk’s fourth biodiversity project and our most significant in Australia. Together with our partners we aim to rehabilitate the property and turn it into a thriving wildlife sanctuary and release zone for native endangered species.

Conservation organisations Aussie Ark, WildArk, Re:Wild and Australian Reptile Park have secured for protection 1,500 hectares of bush habitat in Upper Mongogarie New South Wales. The site is located approximately 30 kilometers from the world heritage listed Mallanganee National Park and 70 kilometers from the Richmond Range National Park. The soon to be sanctuary is located within one of the most bio-diverse regions in Australia, reflected by the diversity of vegetation communities which support a range of mammals, birds, reptiles, frogs and invertebrates.
Plans for the property named Mongo Valley Wildlife Sanctuary, include the creation of a feral-free sanctuary fit to host the return of a suite of endangered Australian wildlife. The wildlife refuge will be modelled off Aussie Ark’s successful Wildlife Sanctuary creation model started in the Barrington Tops of New South Wales.
The sanctuary is to be modelled off of the successful Barrington Wildlife Sanctuary in the Barrington Tops region of New South Wales. The Barrington Wildlife Sanctuary has already proven successful, hosting the return of both the Eastern Quoll and Tasmanian Devil – both species have been extinct on the mainland for some time. Since their return the organisation has reported successful wild breeding of both species, proving just how well the model of protected sanctuaries work.
Teams from Aussie Ark, WildArk and the Australian Reptile Park have been busy visiting the site when possible to conduct wildlife surveys, start weed management programs and begin planning for the construction of the feral predator proof fence.

Aussie Ark, NSW’s largest independently owned and operated conservation organisation, houses seven keystone species once native to the Barrington Tops. Our vision is to create robust insurance populations of threatened Australian mammals like the Tasmanian Devil, Eastern Quoll, and Long-Nosed Potoroo, suitable for release into predator-free sanctuaries and eventual reintroduction to the wild.
