Deteriorating water quality is one of the biggest threats to the Great Barrier Reef. Vital protection and recovery efforts are taking place in the catchments adjoining this national treasure's coastline.

Northern Australia is home to a diverse and unique range of waterbirds. Scientists have created four functional groups of waterbirds, helping decision makers better understand the potential impacts of water and agricultural development in the north.

We’ve used a novel ecosystem modelling approach to demonstrate how river flows are the lifeblood of marine ecosystems in the Gulf of Carpentaria.

A dam wall and water

A new national forecasting service is giving dam operators, river managers – even kayakers – a clearer picture of river and stream flows up to a week in advance. Paradoxically, uncertainty is a key to more reliable forecasts.

Management of the Lower Lakes system in South Australia has been informed by extensive science. Understanding the impacts of climate change and adaptation remain future challenges for the region and the Murray-Darling Basin as a whole.

A failure to grasp the details of the life of freshwater crocodiles in the places they live is likely to bedevil their conservation.

With many surface water storages, such as reservoirs, empty or critically low, groundwater (underground aquifers fed by rainfall and found in cracks or pores in rock) supplies are critical for many Australian communities and industries.

While knowledge of water availability is key to managing Murray-Darling Basin water resources, a commensurate understanding of ecosystem ecological response to flow regulation is also required to aid environmental management.

There’s an upside to the carbon-rich, black water that sometimes flows off the floodplains and into the rivers of the Murray–Darling Basin.
