South of Narrabri, on Gamilaraay Country, the Pilliga spreads across more than half a million hectares of cypress, ironbark and pale sand, the biggest native forest west of the Great Dividing Range. For most of the last hundred years some of its smallest residents were missing, the diggers and burrowers that once turned its soil every night. Since 2018 they have been coming home. In a safe haven inside the Pilliga State Conservation Area, the Australian Wildlife Conservancy and the NSW National Parks and Wildlife Service released 60 greater bilbies in November 2018, and bilbies now live and breed across the whole of the haven. Bridled nailtail wallabies followed in 2019, 42 of them, and by 2025 the estimate stood at 385\. Brush tailed bettongs arrived in August 2022, 55 animals from two Western Australian sanctuaries. Plains mice and Shark Bay bandicoots came in 2023\. Western quolls are next on the list.

Small animals, big jobs. NSW National Parks calls them ecosystem engineers: every time a bilby or a bettong digs for dinner it loosens the soil, lets rain and seed sink in, and leaves a pocket of shelter for something else. Dr Vicki Stokes, senior wildlife ecologist with the Conservancy, said it was thrilling to see the bettongs bouncing around the Pilliga after such a long absence, and that one more secure population makes the whole species safer. Atticus Fleming, head of the NSW National Parks and Wildlife Service when the bettongs went in, called their return an historic step and great news for the Pilliga forest.

On 29 June 2026 the NSW Government signed on for another ten years, here and at two sister sites, Mallee Cliffs National Park with the Conservancy and Sturt National Park with the University of New South Wales Wild Deserts program. Across the three, 13 mammal species that had gone from the state are living wild again, five of them in the Pilliga. Penny Sharpe, NSW Minister for the Environment, put it simply: "Bilbies, Numbats and Shark Bay Bandicoots are back where they had disappeared from and they're thriving." Tim Allard, chief executive of the Australian Wildlife Conservancy, said the partnership had proven what lasting collaboration can deliver for conservation in Australia. It began in 2016 as a new way for a public parks service and a charity to share one job. Ten years on, it has a decade more to run, and a forest full of diggers to show for it.
