Dugong survey reveals thriving population in far north Queensland

The 2023 Dugong Aerial Survey estimates nearly 7,000 dugongs in the region. This is almost double the numbers reported in central and southern Queensland.

The survey which is undertaken as part of NESP Project 3.10, has monitored dugong populations along Queensland’s coast every five years for the past 30 years. Over the past 17 years, the far northern dugong population has shown a 2% growth. This positive trend contrasts sharply with the troubling decline observed further south.

Dr Chris Cleguer, lead researcher from TropWATER, emphasised the significance of these findings. “It’s encouraging to see dugong populations thriving in the far north. These results are vital for guiding future conservation efforts,” he said. The report also identifies consistent dugong hotspots, particularly north of Cape Flattery and Cape Melville and in sheltered bays.

However, Dr Cleguer noted the need for more location-specific data on seagrass health, the main food source for dugongs. “Understanding seagrass health across Queensland, including offshore areas, is crucial for predicting changes in dugong populations,” he explained.

The project, which is jointly funded by the Marine and Coastal Hub along with the Australian Government’s Reef Trust and the Great Barrier Reef Foundation, underscores the importance of ongoing monitoring to inform conservation efforts and protect these iconic marine mammals.
