“After carefully considering all the information necessary for me to make my final decision, including the recent comments on my proposed decision by the proponent, the Queensland Coordinator-General and the relevant federal ministers, I have concluded that the Traveston Crossing Dam cannot go ahead without unacceptable impacts on matters of national environmental significance,” Garrett said. “As I stated when I made my proposed decision on this project, all of my decisions under the national environment law are based primarily on science, and the science is very clear about the adverse impacts this project would have on the nationally protected Australian lungfish, Mary River turtle and Mary River cod.”
The minister pointed out that independent expert advice, and the advice from his department, showed the Traveston Dam proposal would lead to serious and irreversible consequences for these species and most likely, would lead to their further decline.
“The Australian environment is under pressure on numerous fronts, and much of our unique wildlife is suffering under the impact of threats including invasive species, habitat loss and the effects of climate change. We’re working hard to respond to these and other threats, and sometimes this requires tough decisions to be made,” he added. “In this context, I want to make clear that in making my final decision on this matter I had regard to the overriding objects of the Environment Protection and Biodiversity Conservation Act 1999, including the protection of the environment, the conservation of biodiversity, and the promotion of ecologically sustainable development and the need to consider the precautionary principle in making my decision.”
Garrett said dams could play a valuable role in terms of water supply, when well located and carefully designed. The Hinze Dam and the new dam at Wyaralong were approved over the past two years.
“For the Traveston Dam proposal, however, the species’ breeding and their ability to maintain their population numbers would be seriously affected by the flooding of their habitat and by the fragmentation of significant populations, and I was not satisfied that adequate measures were proposed to mitigate these impacts.
“While I acknowledge that the proponent did a great deal of work trying to devise measures to mitigate the impact of the dam on threatened species, and the Coordinator-General proposed some 1,200 conditions of approval, the reality is that the effectiveness of the measures being proposed was highly uncertain, a number of these measures couldn’t be tested until the dam was operational and the impacts were already being felt.
Throughout the assessment process a range of measures were suggested to protect the Mary River environment and the threatened species that rely upon it. Garrett said he believed there are practical measures that should be implemented to protect the species including rehabilitation of riparian corridors, improved cattle fencing around sensitive habitat, and finalisation of a recovery plan for the Australian lungfish, and that these measures should still be undertaken despite the proposal not proceeding.
“I believe that it’s critical that both local and state government work together to tackle the threats to these species and secure their future. My department is currently examining the possibility of pursuing a regional recovery plan for the area,” he said. “In making my decision I also carefully considered relevant economic and social matters. Independent analysis of this proposal cast serious doubt over its economic merits. I also had regard to the significant concerns raised by the communities in the Mary Valley that would be most directly affected by the dam.
Garrett said that he was well aware of the need for long-term water security for South East Queensland but noted that the Coordinator-General's report identified that the water to be provided by the proposed dam was unlikely to be required prior to 2026, and that there are a number of alternative water supply options available to the Queensland Government.
The Traveston Dam proposal was assessed by the Australian Government because it had the potential to impact on nationally listed threatened species, migratory species, the Great Sandy Strait Ramsar wetland, and the World Heritage values of Fraser Island.
The dam had been proposed by Queensland Water Infrastructure Pty and had been scheduled for completion by 2016/2017, It would have been located on the Mary River supplying up to 70,000 megalitres per year.
In early October, the first stage of the dam had been approved by Queensland’s Co-ordinator General, dependent on a number of environmental conditions. In a statement released at that time, Queensland Premier Anna Bligh said the dam was the best and cheapest water supply option, and would create 770 construction jobs for the region
