Problems with the Murray-Darling Basin plan just keep mounting and the NSW Northern Rivers needs to make sure these problems don't become ours


When it comes to the Murray-Darling Basin river systems there is never any really good news - we go from reports of town water shortages, pictures of permanently dry river beds and allegations of widespread water theft to the possibility of a fundamental legal error in the master plan circa 2012.

The Guardian, 2 May 2018:

One of Australia’s foremost lawyers has issued an extraordinary warning that the Murray-Darling basin plan is likely to be unlawful because the authority overseeing it made a fundamental legal error when it set the original 2,750-gigalitre water recovery target in 2012.

Bret Walker QC, who chairs the South Australian royal commission into the Murray-Darling basin plan, issued the warning in a second issues paper. He also spelled out the far-reaching implications of the plan being unlawful.

Not only does it mean that the original water recovery target of 2,750GL was likely to have been set too low to deliver the environmental goal of the Water Act and could be challenged in court, but it also means that amendments to the plan now being debated by the Senate are likely to be invalid as well.

These include a plan to trim 70GL from the northern basin water recovery targets and a suite of projects, known as the sustainable diversion limit adjustment projects, which would be funded in lieu of recovering 605GL in the southern basin.

Both are being strongly criticised by scientists and environmentalists because they believe that they further undercut the environmental outcomes of the plan. 
The Murray-Darling Basin Authority (MDBA) says it has relied on the best available science in recommending the changes.

The new uncertainty over the validity of the amendments will make it difficult for crossbenchers to support them as the Coalition government has urged.

Walker has provided a roadmap for environmental groups or an individual affected to challenge the plan in court.

At the heart of his advice is his view that the Water Act directs the MDBA to ensure environmental outcomes are achieved when it set the environmentally sustainable level of take (ESLT) from the river system. This is the flipside of setting the water recovery target.

But instead of considering the environmental outcomes only, the MDBA applied a triple bottom line approach, giving equal weight to social and economic impacts of water recovery.

“The MDBA also appears to have approached the word ‘compromise’ in the definition of ESLT in a manner involving compromise between environmental, social and economic outcomes rather than in relation to the concept of ‘endangering’ or ‘putting in danger’ environmental criteria such as key environmental assets, and key ecosystem functions,” the SA royal commission said.

 “The commissioner is inclined to take the view that this approach to the word ‘compromise’ in s4 of the Water Act is not maintainable, or alternatively that he is presently unable to see how it is maintainable,” the paper says.

“There is also evidence that recovering an amount of water for the environment of 2,750GL does not, as a matter of fact, represent an ESLT in accordance with the definition of that term under the Water Act.”

Walker pointed to numerous reports, including a 2011 CSIRO report which said modelling based on a 2,800GL recovery target “does not meet several of the specified hydrological and ecological targets”.

There is also evidence that the MDBA received legal advice on more than one occasion, consistent with the commissioner’s concerns.

The issue of water sustainability in the Murray-Darling Basin affects not just those living in the basin and the economies of the four states this large river system runs through – it also affects the bottom line of the national economy and those east coast regions which will be pressured to dam and divert water to the Basin if its rivers continue to collapse.

One such region is the Northern Rivers of New South Wales and in particular the Clarence River catchment area and the Clarence Valley Local Government Area.

Almost every year for the past two decades there have been calls to dam and divert the Clarence River – either north into south-east Queensland or west over the ranges into the NSW section of the Murray Darling Basin.

The latest call came last month on 18 April from Toowoomba Regional Council in south-east Queensland:



The response came on 24 April via NBN News and it was a firm NO:

However, because communities in the Murray-Darling Basin have for generations refused to face the fact that they are living beyond the limits of long-term water sustainability and successive federal governments have mismanaged water policy and policy implementation, such calls will continue.

These calls for water from other catchments to be piped into the Basin or into SE Queensland are not based on scientific evidence or sound economic principles. 

They are based on an emotional response to fact that politicians and local communities looking at environmental degradation and water shortages on a daily basis are still afraid to admit that they no longer have the amount of river and groundwater needed to maintain their way of life and, are wanting some form of primitive magic to occur.

The Clarence River system is the most attractive first option for those would-be water raiders, but experience has shown the Northern Rivers region that once a formal investigation is announced all our major rivers on the NSW North Coast become vulnerable as the terms of reference are wide.

The next National General Assembly of Local Government (NGA) runs from 7-20 June 2018.

If Toowoombah Regional Council’s motion is placed on the assembly agenda it is highly likely that a number of councils in the Murray-Darling Basin will announce their support of the proposal.

Northern Rivers communities need to watch this NGA closely.
