Located in Lithgow on the edge of the Greater Blue Mountains World Heritage Area, the 200 acre Secret Creek Santuary was established in 2003 with the creation of the Eastern Quoll breeding facility. Secret Creek is part of a national breeding program under the Eastern Quoll Management Group.
The next step in developing Secret Creek as a conservation reserve was to construct a ten acre feral-proof fence to exclude foxes, cats, wild dogs and rabbits from the area, creating a safe bushland environment. Within this sanctuary many breeding conservation programs have been established to secure the future of threatened native species; these include pure-breed Dingos, Long-nosed Potoroos and Rufous Bettongs, endangered Spotted-tailed Quolls, Brush-tailed Rock-wallabies, Red-necked Pademelons and Coastal Emus.
Secret Creek Sanctuary is the keystone of AEFI's wildlife conservation programs. Many of the species that are currently being bred at Secret Creek will eventually be reintroducted into their natural habitats.
