Australia Zoo is a 100-acre (40 ha) zoo located in the Australian state of Queensland on the Sunshine Coast near Beerwah/Glass House Mountains. It is a member of the Zoo and Aquarium Association (ZAA), and is owned by Terri Irwin, the widow of Steve Irwin, whose wildlife documentary series The Crocodile Hunter made the zoo a popular tourist attraction. The zoo is run by Director Wes Mannion.

Australia Zoo was opened by Bob and Lyn Irwin on 3 June 1970 under the name Beerwah Reptile Park. Their son Steve, had helped his parents since childhood to care for crocodiles and reptiles and to maintain the growing number of animals in the zoo. In 1982 the park was renamed to the Queensland Reptile and Fauna Park and the area was doubled with the purchase of another 4 acres (1.6 ha). Steve and Terri changed the name of their now growing wildlife park to Australia Zoo. As filming generated extra funds, Steve and Terri put all money raised from filming and merchandise into conservation and building new exhibits.

Australia ( /əˈstreɪljə/), officially the Commonwealth of Australia, is a country in the Southern Hemisphere comprising the mainland of the Australian continent as well as the island of Tasmania and numerous smaller islands in the Indian and Pacific Oceans. It is the world's sixth-largest country by total area. Neighbouring countries include Indonesia, East Timor and Papua New Guinea to the north; the Solomon Islands, Vanuatu and New Caledonia to the north-east; and New Zealand to the south-east.

For at least 40,000 years before European settlement in the late 18th century, Australia was inhabited by indigenous Australians, who belonged to one or more of roughly 250 language groups. After discovery by Dutch explorers in 1606, Australia's eastern half was claimed by Great Britain in 1770 and settled through penal transportation to the colony of New South Wales from 26 January 1788. The population grew steadily in subsequent decades; the continent was explored and an additional five self-governing Crown Colonies were established.

Stephen Robert "Steve" Irwin (22 February 1962 – 4 September 2006), nicknamed "The Crocodile Hunter", was an Australian wildlife expert, television personality, and conservationist. Irwin achieved worldwide fame from the television series The Crocodile Hunter, an internationally broadcast wildlife documentary series which he co-hosted with his wife Terri. Together, the couple also owned and operated Australia Zoo, founded by Irwin's parents in Beerwah, about 80 kilometres (50 mi) north of the Queensland state capital city of Brisbane. Irwin died on 4 September 2006 after being pierced in the chest by a stingray barb while filming an underwater documentary film titled Ocean's Deadliest. The Sea Shepherd Conservation Society ship MY Steve Irwin was named in his honour.

Irwin was born on his mother's birthday to Lyn and Bob Irwin in Essendon, a suburb of Melbourne, Victoria. He moved with his parents as a child to Queensland in 1970, where he attended Landsborough State School and Caloundra State High School. Irwin described his father as a wildlife expert interested in herpetology, while his mother Lyn was a wildlife rehabilitator. After moving to Queensland, Bob and Lyn Irwin started the small Queensland Reptile and Fauna Park, where Steve grew up around crocodiles and other reptiles.
