Objective To determine whether natural and built assets on Victoria’s coastline are being protected against coastal erosion and inundation.
Issues Victoria’s natural and built coastal assets provide social, cultural, economic and environmental benefits for all Victorians. They support commercial uses such as ports, shipping, fishing and tourism, as well as providing other benefits such as storm protection, recreational opportunities, biodiversity, cultural and heritage values. The total economic value of coastal resources is estimated to be $18.3 billion annually.
However, impacts from inundation and erosion have the potential to be exacerbated as a result of sea-level rise and more frequent and extreme weather events. This is placing increased pressure on built and natural coastal assets. It has been estimated that in Victoria, the 1.1-metre sea-level rise expected under higher-end sea-level rise scenarios for 2100 would put between 31 000 and 48 000 residential buildings and $22 billion of coastal infrastructure at risk of damage or accelerated degradation. This figure does not include the cost associated with impacts on natural assets, such as beaches and tourism icons, like the Twelve Apostles.
This audit will examine the adequacy of individual agency risk-management approaches, the cost-effectiveness of these and statewide coordination in managing coastal assets.
Proposed agencies The Department of Environment, Land, Water and Planning (DELWP), Parks Victoria, VicRoads, East Gippsland Shire Council, Mornington Peninsula Shire Council, Gippsland Ports and the Great Ocean Road Coast Committee.
