Largest open-range zoo

The world's largest open-range zoo is Monarto Zoological Park (aka Monarto Zoo), whose total area spans more than 1,500 hectares. It is located in Monarto, approximately 70 km from the centre of South Australia's capital city, Adelaide, and is administered by the Zoological Society of South Australia. It contains several major habitat zones, including African plains, North African arid terrain, Asian grasslands, and Asian steppes, but is also heavily involved in conservation projects for many endangered native Australian species. It was created in 1983, and formally opened to the public in October 1993.

Monarto Zoo began life as a purpose-breeding centre that was closed to the general public until 1993, and houses more than 50 species of animal, including many non-native African and Asian species. Indeed, it is home to the largest giraffe herd in Australia, as well as to one of the largest lion prides there. Among the endangered native and non-native species that the zoo is breeding and conserving are the greater rabbit-eared bandicoot or bilby, Tasmanian devil, tammar, yellow-footed rock wallaby, scimitar-horned oryx, Cape hunting dog, southern white rhinoceros, and addax, and it has one of the most successful giraffe breeding programmes in the whole of Oceania.
