Victoria's Coastline Faces Climate Threat
11 Oct
Summary
- Coastal defenses in Victoria are aging and vulnerable to climate impacts.
- A flood study and adaptation plan is underway for Riverview Caravan Park.
- Multiple coastal communities across Victoria are experiencing erosion and flooding.
Coastal communities in Victoria are facing escalating threats from climate change, including erosion, sea level rise, and stormwater flooding. The Riverview Family Caravan Park in Ocean Grove, a popular holiday destination, is protected by an aging levee that is showing signs of wear. A recent report identified this levee as a hotspot for coastal inundation, with projections indicating it could be fully submerged by 2100 under current sea level rise scenarios.
To address these vulnerabilities, the Department of Energy, Environment and Climate Action has secured $250,000 in federal funding to conduct a flood study and develop an adaptation plan for the Riverview Caravan Park levee. This initiative aims to inform the design of crucial flood mitigation infrastructure. Separately, the City of Greater Geelong has mapped flood risks in its suburbs, revealing extensive stormwater flooding concerns, and is urging state government support for infrastructure upgrades.
Similar challenges are being experienced statewide. The Mornington Peninsula Shire is seeking funds to restore its Portsea front beach due to erosion, exploring options like a new seawall or elevated boardwalk. Inverloch, on the Bass Coast, has undergone extensive beach renourishment to protect its coastline, though other areas within the shire also remain under threat.
