1970–1992

Australia Zoo was opened by Bob and Lyn Irwin on 3 June 1970 under the name Beerwah Reptile Park. Bob is a world-renowned herpetologist, who is regarded as a pioneer in the keeping and breeding of reptiles, while Lyn was one of the first to care for and rehabilitate sick and injured wildlife in southeast Queensland.^[3][7] Bob and Lyn passed on their love and respect for wildlife to their three children: Joy, Steve, and Mandy. Steve had helped Bob and Lyn 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 the Queensland Reptile and Fauna Park and the area was doubled with the purchase of another 4 acres (1.6 ha). In 1987, the Crocodile Environmental Park was opened in an effort to aid saltwater crocodile protection. By the 1990s the Crocodile Environmental Park had become very popular and was seen as unique for its display of crocodile feeding within the park.^[3][8] The area was mainly used to house adult saltwater crocodiles that had been captured and relocated from the wild.

1992–2006

The 1990s brought many changes: Bob and Lyn retired and moved to Rosedale, Queensland, while Steve and Terri changed the name of their now growing wildlife park to Australia Zoo.^[9] As filming generated extra funds, Steve and Terri put all money raised from filming and merchandise into conservation and building new exhibits. Their philosophy was that the zoo animals came first, the zoo team came second, and the zoo visitors came third. The zoo also expanded with the creation of a management team and hiring around 50 staff.^[8] Australia Zoo won the Australian Tourism Awards for 2003–2004 in the category Major Tourist Attraction.^[10] In 2004, the Australian Animal Hospital was opened next to the zoo to help with animal care and rehabilitation. The facility was built in an old avocado packing shed, and was dedicated to Lyn. The facility had a single operating room, and with a staff of 20 full-time workers and 80 volunteers, it cared for up to 6,000 animals per year.^[11][12] Steve Irwin died in 2006, the same year Australia Zoo Retail won the Tourism Retailing Award from Qantas Australian Tourism Awards.^[13]

2007–present

In 2007, the zoo and the Government of Queensland made a land deal involving giving a parcel of land from the Beerwah State Forest to Australia Zoo in return for land near Peachester State Forest which was transferred to the government for forestry. The swap permitted the development of an open-range safari attraction, allowing the zoo to expand to a world-class standard.^[14] In 2008, a new $5 million animal hospital, claimed to be the largest wildlife hospital in the world, opened next to the packing shed. The new 1,300-square-metre (14,000 sq ft) facility is built of mud brick and hay. It contains two operating theatres with viewing areas for student veterinarians, two treatment rooms, intensive care units for mammals, birds, and reptiles, a X-ray room, and public areas including a drop-off area, pharmacy, nursery, and waiting room. A conference room in the building will be rented out to help generate operating funds.^[11][12]

On 15 March 2008 the Brisbane-based newspaper, The Sunday Mail, claimed there are plans to sell Australia Zoo to Animal Planet and create a $100-million Disney-style wildlife theme park. Terri has publicly announced that she has no plans to sell the zoo, but is looking to expand the park. Despite rumours that she intended to return to the United States, Terri denied the claims and became an Australian citizen on 20 November 2009.^[15]

During the 2019–20 Australian bushfire season, the Wildlife Hospital associated with the zoo treated its 90,000th injured animal.^[16]

The Crocoseum

The 'Mount Franklin Crocoseum' stadium at the zoo has a seating capacity of 5,000. It is used mostly for animal shows. At the time of its construction, it was the first in the world where snake, bird and crocodile shows were conducted. Australia Zoo calls this the 'Australia Zoo Wildlife Warriors Show'. This is also where the zoo presents concerts, such as the Summer Down Under series.

Africa

On 17 September 2011, the zoo opened its African Safari exhibit, a multi-species replica of the Serengeti ecosystem, showcasing giraffes, plains zebra and southern white rhinos' interacting as they would in the wild. Also on display are cheetahs, but not in the area where the other animals are. There is also an exhibit for meerkats next to the big savanna who share their exhibit with wandering helmeted guineafowls. This area of the zoo includes Queensland bottle trees reflecting the native African baobab tree and mock kopjes as seen in southern Africa.

Tiger Temple

Opened in April 2005, this exhibit houses Sumatran tigers (and previously also Bengal tigers). The exhibit was built to resemble the Angkor Wat temple in Cambodia. It is enclosed on two sides by glass, and includes an underwater viewing area.

Elephantasia

Elephantasia is a 12-acre (4.9 ha)^[19] Asian themed exhibit that opened in 2006 and is the largest elephant enclosure in Australia. It includes a wading pool with a fountain, and tropical gardens with shaded areas for the zoo's elephants. In October 2019 Australia Zoo imported four female Sumatran elephants. The elephants are on display in Elephantasia as of December 2021.

Aviary at the Australia Zoo

Rainforest Aviary

The Rainforest Aviary is an outdoor walk-through aviary housing about 150 birds, most of which are native to Australia. Adjacent to the Rainforest Aviary is the Birds of Prey aviary, which holds various species of raptors and other predatory birds. Following the birth of Bindi Irwin's daughter the Rainforest Aviary was renamed Grace's Bird Garden.

Bindi's Island

Opened beside the Africa exhibit in December 2014 and named after Steve's daughter, Bindi's Island is a three-story "treehouse" built around a replica fig tree. It offers panoramic views of Australia Zoo, including the adjacent lemur island.

Robert's Reptile House

The zoo's indoor reptile exhibits which showcase twenty different species of reptiles (and three species of frogs) in sixteen different terrariums.

Other Exhibits

Further exhibit zones include Crocodile Environmental Park, Roo Heaven, Wetlands and others.

Crikey! Cafe

Visitors can eat at the open air upper story "Crikey! Cafe" (which seats up to 1,500), at the Dingo Diner, or at several food vending stands around the zoo.

Transport

To get around the zoo, visitors can take Steve's Safari Shuttle, a 'modified trailered bus' that operates on a bitumen (asphalt) roadway circuit. Visitors can also hire a caddie with guide to drive around the zoo for the day.

Playgrounds

The zoo includes multiple shaded playgrounds as well as a jumping pillow and water splash park.

Wildlife Warriors

Wildlife Warriors runs a rescue operation and care station for any native wildlife which may be injured in accidents outside the zoo.^[22]

This effort is now supported by the 1,300-square-metre (14,000 sq ft) Australia Zoo Wildlife Hospital next to the zoo, which can care for up to 10,000 animals per year, with two operating theatres, two treatment rooms, intensive care units for mammals, birds, and reptiles, and an X-ray room, and was designed by WD Architects.^[12] The hospital is named in honour of Steve Irwin's mother Lynn Irwin, who died in a car accident in 2000.

Steve Irwin Wildlife Reserve

This 135,000-hectare (330,000-acre) property was acquired with the assistance of the Australian government as part of the National Reserve System Programme. It is located on the Cape York Peninsula in Queensland, and contains spring fed wetlands that provide a water source to threatened habitat and the Wenlock River.^[23]

Iron Bark Station (Blackbutt)

Australia Zoo purchased the 3,500 acres (1,400 ha) Iron Bark Station located at Blackbutt, Queensland in 1994. It is part of the great dividing Range, where the East coast meets the dry West. An additional 325 acres (132 ha) was purchased in 1994 to save a dwindling koala population, with fewer than 12 koalas left in the area. Management immediately commenced reforestation, including 44,000 eucalypt trees for koalas. In 1998, another 325 acres (132 ha) was purchased. In 1999, a 5 acres (2.0 ha) release facility was established to rehabilitate native marsupials the area. Another 1,000 acres (400 ha) was purchased in 1999 with funds from the Lynn Irwin Memorial fund (now Wildlife Warriors Worldwide), and another 1,800 acres (730 ha) was added in 2002. In 2007, Bob Irwin became full-time manager of the station.^[24]

Mourachan (St. George)

This conservation area was developed to protect endangered species, such as the woma python and yakka skink. It consists of 117,174 acres, in which various habitat types have been created, by Australia Zoo and the Australia Zoo Wildlife Warriors.

It is a place where endangered species can reestablish populations, and as of 2015, Terri purchased an additional 33,000 acres of land to expand this conservation habitat.
