The majestic and elusive platypus, an iconic symbol of Australia's unique wildlife, faces an existential threat from the Queensland Labor Government's Pioneer-Burdekin Pumped Hydro Project. Despite assurances from Queensland Hydro (the government owned business tasked with the project) that they will relocate these precious creatures, the reality is far more dire. The plan to relocate hundreds of platypus is not only impractical but also fraught with high mortality rates, casting a dark shadow over the future of these remarkable animals.
The Grim Reality of Relocation
The Queensland Hydro proposal to relocate the platypus population from the inundation zones of the reservoirs might sound like a feasible solution. However, the numbers tell a different story. With over 12 kilometres of water courses within the footprint of Reservoir A alone, and considering there are three reservoirs in total, the scale of this task is monumental. Reservoir A encompasses more than 10 significantly sized water holes or dams, along with an intricate network of springs, creeks, rivulets, and smaller water holes.
The entire catchment area is fed by natural springs, with water bubbling up from holes in the ground and into larger water bodies. During rainfall events, the catchment drains through Pla Creek, but much of the area remains saturated with spring water. This complex and rich aquatic ecosystem flows directly into Eungella National Park, estimated to be home to over 1000 platypus.
High Mortality Rates in Relocation Efforts
The mortality rate associated with relocating platypus is alarmingly high. Research indicates that the stress of capture and transport, coupled with the challenges of adapting to new environments, can significantly impact the survival of these animals. A study published in The Journal of Mammalogy reveals that while relocation can sometimes aid in population management, it is not always successful due to the platypus's specific habitat requirements and the stress involved in the process. Additionally, research from the University of Canberra highlights the detrimental effects of genetic differentiation caused by dams, which can isolate populations and reduce genetic diversity, further increasing mortality rates (source: The Journal of Mammalogy; Australian Geographic).
The Impact on Eungella's Ecosystem
The disruption of over 12 kilometers of natural water courses and the destruction of intricate spring-fed systems will have cascading effects on the entire ecosystem. Eungella National Park, renowned for its biodiversity, will likely suffer severe ecological consequences. The platypus, being a keystone species, plays a crucial role in maintaining the health of aquatic habitats. Their decline will signify a broader environmental catastrophe, impacting numerous other species and the overall integrity of the ecosystem.
Eungella: The Platypus Capital of the World
Eungella is considered the platypus capital of the world, renowned as the best place to see platypus in the wild. The region’s pristine environment offers a unique and vital habitat for these extraordinary creatures. The Pioneer-Burdekin Pumped Hydro Project threatens to wipe out this platypus stronghold, destroying square kilometres of unique platypus habitat. The loss of such a significant habitat would be an irreplaceable blow to the conservation of the species and to the natural heritage of Eungella.
Documentation and Evidence
Save Eungella has meticulously documented the presence and importance of these natural springs and water systems. Evidence shows that the entire area within the footprint of Reservoir A is a thriving and dynamic aquatic environment. During rainfall events, the natural springs and water holes overflow, feeding into larger water bodies and sustaining the rich biodiversity of the region.

The Queensland Labor Government's Pioneer-Burdekin Pumped Hydro Project, under the guise of sustainable energy, threatens to decimate one of Australia's most cherished species. The platypus, an integral part of Eungella's natural heritage, faces a grim future if this project proceeds. It is imperative that we stand together to protect these incredible creatures and preserve the delicate balance of our ecosystems. Vote Labor last in the October state election.
