First Nations water rights and participation have long sat alongside the Murray–Darling Basin Plan rather than within its core architecture. In the 2026 Basin Plan review, that positioning is under closer examination.
The Discussion Paper acknowledges that First Nations peoples have historically been excluded from water decision-making despite enduring cultural, spiritual, environmental, and economic connections to Basin rivers. The review frames participation not as an adjunct issue, but as a governance question with implications for how water is planned and managed.

What has been the role of First Nations in the Basin Plan to date?
Since the Basin Plan’s introduction in 2012, cultural values have been recognised in principle but not embedded structurally within diversion limits or entitlement frameworks. Cultural flows remain outside the primary allocation system, and representation in decision-making processes varies across jurisdictions.
While engagement has increased over time, the review recognises that consultation does not equate to shared authority. Water planning mechanisms have continued to operate within frameworks developed without recognising First Nations’ sovereignty or water ownership rights.
The Basin Outlook and associated documentation acknowledge that this exclusion has contributed to ongoing disparity.
How is the Basin Plan review addressing participation?
The Discussion Paper signals an intention to strengthen First Nations’ involvement in governance arrangements and review processes. This includes better integration of cultural knowledge into environmental planning, stronger representation in advisory structures and clearer pathways for input into SDL assessment and response development.
However, the review also highlights that many structural levers lie beyond the MDBA’s direct authority. Water entitlements and allocation systems remain primarily governed by state legislation, limiting the scope of Basin-level reform without intergovernmental agreement.
This raises a practical question: whether enhanced participation can occur without concurrent reform of allocation frameworks.
What are cultural flows, and how do they fit within current settings?
First Nations organisations define cultural flows as water entitlements that are legally owned and managed by First Nations to improve spiritual, cultural, environmental, and economic conditions. These differ from environmental water holdings, which are managed for ecological outcomes.
Under current Basin settings, cultural water access remains limited relative to overall entitlement pools. The review does not propose a specific volumetric pathway, but it acknowledges the need to consider how water recovery, allocation and planning mechanisms intersect with cultural objectives.
This places cultural water policy within the broader context of sustainable diversion limits, recovery settings and system constraints.
How does climate risk intersect with cultural objectives?
Climate change introduces an additional layer of complexity. Declining runoff, altered seasonality and reduced floodplain inundation affect not only ecological indicators but cultural practices tied to specific flow events and river conditions.
If environmental baselines shift, cultural access may also be constrained unless governance arrangements adapt accordingly. The review framework recognises that climate risk must be considered alongside equity and participation when assessing long-term water sustainability.
This moves the discussion from symbolic inclusion toward structural resilience.
What governance changes are realistically within reach?
The Sustainable Diversion Limit Assessment and Response Framework separates identification of risk from development of response options. In the context of First Nations participation, responses may include strengthened co-design mechanisms, clearer integration of cultural knowledge into planning instruments, and improved transparency in decision-making processes.
More substantive reform, such as reallocating entitlements or redesigning allocation hierarchies, would require coordinated action across Basin governments.
The review does not pre-empt those outcomes. It establishes participation as a central consideration in the next phase of Basin governance.
The evidence assembled so far indicates that First Nations participation in the Basin Plan review is no longer confined to consultation processes, but is increasingly framed as a structural question within long-term water governance.
