NATIONAL IRRIGATORS’ COUNCIL

POLICY PORTFOLIO - MURRAY DARLING BASIN PLAN

Advocating for the Australian irrigated agriculture industry

The Murray Darling Basin Plan

The Murray Darling Basin Plan became Commonwealth legislation in 2012.  It was enabled under the Water Act 2007.  The plan outlines the management of water resources in the Murray-Darling Basin, including water allocation, environmental water management, and water quality standards.

The Murray Darling Basin Plan has been amended twice since becoming law:

  • 2016: Amendments to reduce the Water Recovery targets for the Northern Basin, enable Sustainable Diversion Limit Adjustment Mechanism and the additional 450GL of environmental water to be achieved with neutral socio-economic outcomes. 
  • 2023: Restoring Our Rivers Bill amended key timelines for implementation, broadened the environmental objectives for the additional 450GL environmental water and enables other mechanisms of recovery without the need for neutral socio-economic outcomes, and removed limits on water purchases.

The National Irrigators Council is committed to finalising the Murray Darling Basin Plan without unnecessarily burdening our industries and communities. The remaining elements of the Murray Darling Basin Plan are shared responsibility of the Australian Government with Basin jurisdictions. We endeavour to monitor their progress to keep them accountable to their promises to achieve the Murray Darling Basin Plan and its outcomes while not leaving any community behind.

Snapshot of environmental outcomes

  • Over the 9-year period, 15,443 GL of Commonwealth environmental water was delivered to 56 ecosystem types representing 249,079 ha of lakes and wetlands, 187,486 ha of floodplain, 27,715 km of waterways and 23,768 ha of estuarine ecosystems - Flow-MER_22-23 Synthesis Report (CEWH).
  • The largest bird-breeding events in the decades in 2022-2023 were supported by natural flows and various forms of environmental water- DCCEEW.
  • Increased abundance in native fish and improved resilience of native fish - CEWH
  • Improved connectivity between the Lakes, Coorong and Murray Mouth with 10 years of continuous flow and increased barrage flows, the maintenance of lake levels and salinities within optimal ranges in SA Lower Lakes - Monitoring Report -CLLMM.
  • The export of at least 4.2 million tonnes of salt through the barrages at South Australia - Benefits of water for the environment (DCCEEW).


Water Recovery Progress

Water recovery towards the Murray Darling Basin Plan Sustainable Diversion Limits and compliance with those limits, is monitored by the Murray Darling Basin Authority.


As reported in the August Sustainable Diversion Limit Water Take Report the Basin Plan Sustainable Diversion Limits are being achieved with all water resource plan units compliant. 


The progress to-date means  that 1 in 3 litres of water for agriculture is now held by environmental water holders.  This is a total reduction in water availability meaning 72% of average river flows are for the environment and 28% to water users.

KEY MESSAGES

The National Irrigators' Council wants to see healthy rivers and wetlands because we are locals too and that is why we are committed to finalising the Murray Darling Basin Plan without unnecessarily burdening our industries and communities and ensuring clear environmental outcomes are achieved.

We  support Governments  focusing on delivering outcomes which benefit the environment, while ensuring local communities can thrive and our food and fibre growers can grow produce for Australians and the nations that rely on us.

We have just put in our submission for the third Water for Environment Special Account (WESA) review - take a look.

Our key recommendation: "The Independent Panel take a broad view to examine the policy settings and decision-making on the use of WESA funds to achieve enhanced environmental outcomes with consideration of socio-economic impact - to ensure WESA can be used transparently to target priority environmental investments. We encourage you to explore the option to amend the WESA to ensure it can be used transparently to target priority environmental investments such as community-supported constraints measures and investment in non-flow complementary measures as evidence within the 2025 Basin Plan Evaluation and Sustainable Rivers Audit."

Thank you to our members who have contributed to this piece of work, and taking the time to provide feedback. 

If there's one video those working in water must watch this year, it's this - Professor Forest Reinhardt from Harvard Business School talking to Andrew McConville at this years River Reflections Conference on water property rights (watch from 45 minutes into Day 1).

One of our favourites (1hr 18mins in) - in response to a question on what a future Basin Plan should look like: "If the subsequent versions of the Basin Plan, can make water more and more like a normal commodity... just as if you own a piece of land... I think that the more you can make water rights look like normal property rights, the more effective the system will be. I come from a country where we can't even get to the starting line of that kind of thing."


Today’s publication of the Murray Darling Basin Authority’s (MDBA) 2025 Basin Plan Evaluation and Sustainable Rivers Audit has found the health of the Basin has improved, advising that “water for the environment is essential, but on its own is likely not sufficient” [MDBA Overview]...  The National Irrigators’ Council has described many parts of the Evaluation as refreshing and a wakeup call needed to shape thinking in the Basin going forward and is calling for more quick thinking on how to determine and prioritise a package of strategic environmental investments in these complementary (non-flow) measures to inform next steps on the Basin Plan, given the Evaluation found this as a missing piece of the current Plan puzzle.  [...]

Basin communities fear socio-economic impact assessments soon to be released by the Murray-Darling Basin Authority (MDBA) will water down the true impact, overlooking community and industry-level data, in their Basin-scale assessment. “Basin Plan legislation requires 5-yeraly Evaluations, but at a Basin-scale”, said Zara Lowien, National Irrigators’ Council (NIC) CEO, “we know the most severe impacts are felt at a local community level, and within specific industries, but these impacts get smoothed out when the assessment zooms to the Basin-scale.”  [...]


NIC Members agreed to a specific Position Statement on the reliability of water access entitlements to provide a clear message to Governments on how decisions impact water property rights, as represented and agreed in the National Water Initiative.

This position statement was prepared in conjunction with our guiding principles.

Approved 17 July 2025.

14th May 2025, Canberra, ACT: The National Irrigators’ Council (NIC) congratulates Murray Watt on his appointment as the Minister for the Environment and Water, saying this is an opportunity for new leadership to put policy above politics and partnerships over partisanship. “Until recently, water management in Australia has had a long history of bipartisanship across politics.  We hope under new leadership... we can see a return to respectful and constructive water policy solutions, that can once again rise above politics,” said NIC CEO, Zara Lowien.
