Cohunu Koala Park, Wildlife refuge and zoo in Byford, Australia.

Cohunu Koala Park occupies 14 hectares of bushland at 103 Nettleton Road, Byford, south of Perth. Its koala colony numbers over 25 animals from both the northern and southern subspecies. The grounds also hold wombats, kangaroos, wallabies, quokkas, echidnas, dingoes, emus, cockatoos, freshwater crocodiles and bobtails, alongside lifelike dinosaur replicas.

Lucille and Nardino Sorbello began establishing Cohunu Wildlife Sanctuary in 1972 on about 16 hectares at 322 Mills Road East, Martin, near Gosnells, and it opened to visitors in mid-1975. Four koalas arrived from South Australia in 1982, founding the colony, and the site was renamed Cohunu Koala Park in September 1991. In 2009 the park moved to 103 Nettleton Road, Byford.

The name Cohunu comes from the initial syllables of Cooinda, Hunter and Nardino, the family members of founders Lucille and Nardino Sorbello. Visitors can hold and be photographed with a koala between 10 am and 4 pm for an extra charge, and may touch and hand-feed other animals such as kangaroos and wallabies. The colony holds over 25 koalas of both the northern and southern subspecies.
