The Global Significance of the Fitzroy RiverThe Martuwarra Fitzroy River, which flows 700km through the Kimberley to King Sound, is considered the last stronghold for sawfish globally and is home to four of the world's five species. This untamed river ecosystem supports largetooth, dwarf, green and narrow sawfish, all protected under national environment laws. The river, its estuary and near-shore marine environment provide a critical habitat that represents what a relatively untouched sawfish population looks like on a global scale.The Water Extraction PlanA Western Australian government proposal aims to increase groundwater allocation from about 32GL to 75.7GL in the Fitzroy River catchment. While the draft water plan, now out for consultation, has proposed no additional surface water allocations and no dams on the river, environmental groups are particularly concerned about the increased groundwater extraction. The underground water stores feed several large pools and wetlands that act as crucial refuges for sawfish and other species during long dry periods.The Ecological ImpactEndangered largetooth sawfish, the largest and most imperilled species, are born at the river's mouth and spend several years inhabiting the river, its tributaries and deep aquifer-fed pools before heading out to sea. Adults can reach up to seven metres in size. Conservationists warn that sawfish won't survive without these refuge pools, which also provide life support for barramundi, a whole range of other fish, freshwater prawns and big trees and vegetation that sustain birds, possums, bats and insects.The Indigenous PerspectiveDr Anne Poelina, executive chair of the Martuwarra Fitzroy River Council, an alliance of elders and young leaders from traditional owners of the catchment, emphasized that water is precious and a life force. She stated that the lived experience of Aboriginal people on country is that the river is already stressed, and continued decline will affect people's lives and livelihoods as well as the environment, including access to clean drinking water and the rising cost of living. Poelina called for more time to gather information before any additional licences are granted.The Scientific ConcernDr Leonardo Guida from the Australian Marine Conservation Society described sawfish as "probably one of the most unique looking animals on the planet." Martin Pritchard from Environs Kimberley noted that the underground water stores that feed refuge pools are "absolutely critical in a landscape that's so hot and dry." Dr Ryan Vogwill, a hydrogeologist, explained that groundwater plays an "incredibly important" role supporting the high biodiversity and cultural values of the river ecosystem during dry periods when surface water isn't flowing.Future OutlookThe WA government's draft water plan requires applicants seeking a licence to demonstrate "sustainable groundwater use" and "protect water-dependent ecosystems and sites of ecological, cultural and social significance." However, conservationists remain concerned about the potential impacts, especially given the failure of a similar water allocation plan in the Pilbara where groundwater aquifers are in decline. The Fitzroy River has national and Aboriginal heritage list status for its outstanding cultural and natural values, making its protection a matter of significant environmental and cultural importance.
