Coastal homes still popular despite threat of rising sea levels
Tuesday, August 12th, 2008We’re being told that sea levels are on the rise, but that hasn’t slowed down the Aussie love affair with seaside homes. I’ve mentioned before that I thought house prices under threat” href=”http://www.realestatedaily.com.au/2008/06/30/beach-and-canal-house-prices-under-threat/” target=”_self”>low-lying coastal homes could drop in value in a big way if sea levels start rising, but people are still willing to spend a lot of money on a seaside property.
Down in Sydney the suburb of Narrabeen is deemed the one most likely to see the effects of rising sea levels:
“… a sea level rise of just 20 centimetres combined with a one-in-50 year storm would erode the dunes at the famous Sydney surf beach and push the shoreline back by more than 100 metres, according to a confidential draft United Nations report leaked to the Herald.”

Yet last month a property in Narrabeen sold for over $4 million, a rise of 20% since 2005. At the moment the threat of an ocean-generated disaster seems to be generations away, although oceanographer Dr John Hunter, from the Antarctic Climate & Ecosystems Cooperative Research Centre in Hobart suggests that it might be closer than we think. Although there is talk of sea level rises of as little as 18cm - which sounds pretty small - the fact is that for every 1cm rise in sea level the beach will retreat by 1 metre, and that’s massive.
