Bush Blitz is a pioneering biodiversity discovery and knowledge program based on a cross-sector partnership of government, non-government organisations, industry and science (major partners are the Australian Government, BHP Billiton's Sustainable Communicates and Earthwatch). It involves a continent-wide multi-disciplinary survey program and a range of follow up taxonomic and educational programs aimed at better management, conservation and awareness of Australian fauna and flora. Some 29 Bush Blitz expeditions have been undertaken, including six across northern Australia which have included fish as a target group (2012–2015). These surveys occurred on large, remote and often very rugged areas of the central deserts (Henbury Station), Top End (Fish River Station, Wongalara Sanctuary, Judbarra-Gregory National Park), East Kimberley (Karunjie and Durack River stations) and Cape York (Olkola Country), across a combined area of some 3.7 million hectares! Freshwater fish diversity in Australia increases dramatically in the tropical north, and results to date indicate that there is still much to be documented in terms of the species baseline. The surveys recorded areas of significant fish biodiversity, identified several unique forms that may represent new species, uncovered important information on narrow range endemic species, collected high quality morphological and DNA material to contribute to broad systematic reviews of the Australian fish fauna, and developed imagery to help promote fishes and aquatic habitats. Indigenous rangers work alongside researchers in the field sharing knowledge and expertise. Information from surveys is provided back to land managers and traditional owners to assist with property management and feeds into public data portals such as the Atlas of Living Australia. School teachers also work alongside researchers teaching live back to their classrooms via Skype and online blogs as part of the Bush Blitz TeachLive program. Partnerships and engagement are a key part of the success of Bush Blitz.
