Zambi Wildlife Retreat

Zambi Wildlife Retreat is a private-tour zoo, located in Wallacia, New South Wales, Australia in the outskirts of western Sydney, that operates at the former site of the Bullens family property, and adopted some of the Bullen's former animals. The Zambi foundation was established by Silke Bader, Traci Griffiths and Donna Wilson in 2012. It's officially stated focuses is the re-homing captive wild animals such as lions, tigers, Sri Lankan leopard, dingos, wolfdogs, red panda, Mongolian wild horses (takhis), hamadryas baboons, crab-eating macaques, common marmosets, meerkats, hyacinth macaws, Hahn's macaws, blue-and-gold macaws, green-winged macaws, red-tailed black cockatoos, sun conures, koi carp, and until recently the last puma held in Australia.
Visiting is by pre-arranged appointment and donation and tours are said to offers feeding and interaction opportunities with some of the animals. In 2025, the Zambi team rescued three herds of Mongolian wild horses from the nearby abandoned Ferndale Estate at Mulgoa.
