Concerns have been raised about ongoing erosion on the south bank of the Burdekin River, particularly near Home Hill, where experts believe the risk of a channel avulsion—a sudden shift in the river’s course—is at its highest. The erosion has reportedly damaged protective vegetation and riverbank stability, raising questions about the current approach to managing flood and flow-related risks in the Burdekin Delta.
A recent statement by Professor Eric Wolanski (Townsville), Chris Hopper (Townsville), and Chris Canavan (Home Hill) calls for more comprehensive and future-focused planning. The group argues that while the Burdekin River Trust’s $5 million commitment toward bank restoration is a step in the right direction, a more detailed understanding of the river’s physical dynamics is essential.
They suggest that a portion of the funding be used for a full topographic survey of the riverbed and banks, including the underwater terrain. This, they say, would allow for more accurate hydrodynamic modelling and ultimately lead to more reliable long-term solutions. “Waiting for a major flood to trigger significant damage isn’t a viable strategy,” the group noted in their joint statement.
One potential long-term measure put forward is dredging sand from the riverbed to redirect flow and relieve pressure from vulnerable sections of the bank. The group argues that this could be economically viable, as sand is a globally valuable commodity that could be sold to offset operational costs.
The concerns tie into wider research conducted by Wolanski and Hopper on how dams and climate change can accelerate channel avulsion and coastal erosion in river systems such as the Burdekin. Their 2022 paper, published in Ecohydrology & Hydrobiology, highlights the risks posed to Ramsar-listed wetlands in the Great Barrier Reef catchment.
With the region’s economy and community closely tied to the river, discussions about erosion management and flood mitigation are expected to continue among residents, scientists, and government agencies alike.
