Climate change bringing sea-level rise to Victoria’s low-lying towns and suburbs

Rising sea, erosion to wreak havoc in low-lying suburbs: report, The Age , By Benjamin Preiss and Adam Carey

June 23, 2019Rising seas are threatening to encroach on low-lying parts of Melbourne within 20 years, causing flooding and erosion in suburbs including St Kilda, Point Cook, Mordialloc, Seaford and Frankston.

Other places at risk include areas around Queenscliff and Barwon Heads on the Bellarine Peninsula; the south-west Victorian towns of Port Fairy and Portland; and Tooradin, Lang Lang and Seaspray in the state’s south-east.

A report tabled in Victoria’s Parliament last week examines the myriad threats to the state’s fragile coastline, painting an alarming picture of damage to the environment and suburban Melbourne if no action is taken.

The Victorian Environmental Assessment Council report cites a 20-centimetre sea-level rise by 2040 and between 40 centimetres and one metre by century’s end.

Sea-level rise will lead to more frequent inundation of low-lying areas, loss of coastal habitat, cliff, beach and foreshore erosion,” the report says.

“Climate change will also put pressure on ageing coastal infrastructure and ultimately impact on feasibility of living in or developing some coastal locations.”

Increasing storm intensity, coupled with rising seas, will cause extensive erosion of the Victorian coastline by 2040, the report says.

“The most extensive area vulnerable to erosion by 2040 is the Gippsland coast,” it says. “Other coasts at risk include west of Portland, beaches in Port Phillip Bay between Mordialloc and Frankston, and the coast between Cape Paterson and Cape Liptrap in South Gippsland.”

Coastal erosion has already had a dramatic impact on the foreshore at Inverloch, which has receded 33 metres since 2012…….
