The Botanic Gardens and Parks Authority is a Western Australian State Government authority formed in 1999 to replace the 104-year-old Kings Park Board as part of new legislation governing the management of Kings Park and other designated lands such as Bold Park. Kings Park and Bold Park are two of Perth's largest reserves, incorporating the State's Botanic Garden and important urban bushland areas. The Authority's vision is to create and provide world-recognised botanic gardens & parks, and to inspire the conservation of biological diversity. The Authority conducts business from its head office in Kings Park on Fraser Avenue and from the Western Australian Ecology Centre located in Bold Park.
On 1 July 2017, the Botanic Gardens and Parks Authority was amalgamated with the functions and staff of the Department of Parks and Wildlife, Rottnest Island Authority and the Zoological Parks Authority to form the new Department of Biodiversity Conservation and Attractions.
