Shire of Murray and Bindjareb Rangers complete riverbank restoration to protect Cooleenup Island from erosion

Restoration works have finished at Coolenup Island in an effort to protect the area for future generations.

The Shire of Murray commissioned the riverbank restoration at the South Yunderup waterway to stabilise shorelines and prevent ongoing erosion.

Cooleenup Island’s riverbank had sharp scarping, which is when the water erodes a slope into the shore.

To address this, shire staff joined with the Bindjareb Rangers and engineering consultants Syrinx to install brushwall that acts as a temporary barrier when laid across the sand.

The team also installed native rush and sedge seedlings, which will eventually join together and bind sand to further strengthen the riverbank behind the brush — allowing for long-term protection from erosion.

Brushwall works to prevent erosion by collecting sediment as water passes through. This, combined with planting native seedlings, reinforces the riverbanks.

Shire president David Bolt said it was part of the shire’s commitment to ensure Murray’s ecosystem was managed sustainably for the benefit of current and future generations.

“The areas selected for treatment are at a higher risk of erosion due to boat wash and tidal influences, making this restoration particularly critical,” he said.

“Brushwall is soft engineering alternative that allows us to sustainably manage and preserve rivers and waterways.

“The Bindjareb Rangers prepared the brushwall ahead of time and our team supported with installation.”

More restoration works are planned for Yunderup Island this month.
