Summary
The Daly River catchment is one of the four nodes in the Water Security for Northern Australia program. The region includes the Daly River and its tributaries, along with the Katherine, Flora, King and Douglas rivers. These rivers and waterways sustain diverse environmentally and culturally significant ecosystems as well as important agricultural production in mango and broad-acre crops.
Projects
Water Security for Northern Australia program: Implementation phase
The Water Security for Northern Australia Program is a collaborative partnership between the CRCNA and the Northern Australia Universities Alliance (NAUA), delivering targeted research to support sustainable water resource development across northern Australia. Building on the co-design project that identified key challenges affecting water security, agricultural development and equitable water use across four focal nodes: the Gilbert catchment in north Queensland, Lower Fitzroy catchment in central Queensland, the Daly catchment in the Northern Territory, and the Ord River Irrigation Area in Western Australia. Through stakeholder-led co-design, 15 priority research projects were identified to address region-specific and cross-cutting challenges related to water availability, environmental management, agricultural productivity, supply chains and Indigenous access to water resources. These projects are grouped into four interconnected work packages spanning cross-regional research, water quality and environmental outcomes, water availability, cropping systems and alternative economic opportunities. The program is generating practical knowledge to improve water planning, development assessment and environmental management, while identifying opportunities to increase the economic value of water use across northern Australia. Research outcomes are intended to support more informed decision-making, reduce uncertainty and monitoring costs, improve water use efficiency, strengthen supply chain understanding and expand opportunities for Indigenous participation and benefit. Beyond the research itself, the program is building stronger connections between universities, industry, government, Traditional Owners and regional communities. This collaborative approach is helping to strengthen research capability, improve communication between stakeholder groups and support more effective, less contested water resource decision-making across northern Australia.

Water Security for Northern Australia program: Daly River catchment (NT)
The Daly River catchment is one of four focal nodes within the Water Security for Northern Australia (WSNA) program, which is investigating how water resources can support sustainable economic development while protecting culturally and environmentally significant ecosystems across northern Australia. The Daly River region supports important agricultural industries, including mangoes and broadacre crops, and contains one of the Northern Territory’s most significant river systems. This project brings together hydrology, climate science, ecology, agriculture and social science research to better understand the interactions between groundwater, surface water, ecosystems and agricultural development in the Daly River catchment. Research activities include modelling future climate impacts on water resources, improving understanding of the Oolloo Dolostone aquifer and spring systems, assessing the impacts of wet season water extraction on floodplains and ecosystems, and exploring opportunities and barriers for agricultural diversification and sustainable crop production. The project is also working closely with Traditional Owners, government and industry stakeholders to inform future water allocation and management decisions that balance environmental, cultural and economic outcomes. Through improved understanding of water systems, climate risks and agricultural practices, the research aims to support resilient farming systems, biodiversity conservation and long-term water security across the Daly River catchment.

Background: This Water Security for Northern Australia (WSNA) program is being delivered through a partnership between the CRCNA and the Northern Australia Universities Alliance. The WSNA program will develop and implement a series of research projects which address problematic issues which are constraining sustainable water resource utilisation in four key precincts or focal nodes across Northern Australia. These focal nodes are (Gilbert catchment (QLD), Daly River (NT), Ord River Irrigation Area (WA) and Lower Fitzroy catchment (QLD)). These focal nodes were selected by the CRCNA based on prior assessments and consultation indicating they are likely locations of further water resource development pressure. In order to develop such a series of research projects, it was first required that the relevant stakeholders in each focal node be engaged in a co-design process. The four focal nodes were developed through a 5-month engagement phase and now report to regional stakeholder advisory groups: Co-design phase of the Water Security for Northern Australia.
