The Murray Darling Basin Plan
The Murray Darling Basin Plan "the 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 Plan has been amended twice since becoming law:
2017/18: 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 Plan is scheduled for review by the Murray Darling Basin Authority in 2026.
'Moving Forwards:Our
Review into the Murray Darling Basin Plan' is
a series of comprehensive papers by National Irrigators' Council based on the key themes identified by the MDBA in their Early Insights
Paper and aims to start a conversation on how to enable improvements in the Basin Plan and enhance environmental outcomes with the
water already held for environmental purposes.
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-

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 enforcing compliance with current Sustainable Diversion Limits - as the core component of the
Murray Darling Basin Plan.
Future Basin Plan implementation must focus on moving beyond ’just add water’. Governments must optimise
outcomes through being smarter and more strategic with environmental water; investing in complementary measures (such as invasive species
control, fish passageways, habitat restoration, fish screening, riparian land management); and a paradigm shift of working together.

The MDBA have opened registrations for a series of webinars to support their consultation approach on the Basin Plan Review. The initial topics being how to make a submission, Menindee and SDL assessments. The webinars will be recorded and start from Monday next
week.

NIC report reviewed the Federal Government’s purchases and found most have low environmental utility and cannot directly contribute to
today’s environmental priorities in the Basin – despite costing taxpayers billions.“These additional water buybacks go beyond what was
required to ‘bridge the gap’ to get Sustainable Diversion Limits in place for the Basin Plan,” said NIC CEO Zara Lowien “most of this
additional water will not be able to be used as intended and unlikely to contribute to desired environmental outcomes”. [...]
There have been several concerns raised regarding the Federal Government’s decision to purchase additional water from farmers that go beyond
the water recovery required to ‘bridge the gap’ to reduce water usage to Sustainable Diversion Limits (SDLs), in the Murray-Darling Basin
Plan. The concerns relate to the effectiveness or need for additional water acquisition, with questions on how the Government’s actions are
contributing to policy outcomes, meeting value for taxpayers’ money, and consider the growing evidence that signals alternatives approach to
‘just adding water’ are needed to enhance environmental outcomes around the Basin.
This Report by NIC, provides a preliminary assessment of the Federal Government purchases of additional water under “the 450 GL” program of
the Plan. [...]
