Significant episodes of coastal erosion are often associated with extreme weather events (coastal storms, surge and flooding) but also from tsunami, both because the waves and currents tend to have greater intensity and because the associated storm surge or tsunami inundation can allow waves and currents to attack landforms which are normally out of their reach. For example, last year construction began on a controversial 1.3-metre sea wall from Collaroy to South Narrabeen in Sydney's north, designed to prevent future erosion threatening beachfront homes.

Australia is estimated to have around 12,000 kilometres of sandy coastline at risk from potential sea level rises. The above results are from a worst-case scenario. The results for the highest greenhouse gas emission scenario are alarming, but reducing emissions lead to lower rates of coastal erosion. A member of the Wentworth Group of Concerned Scientists, Bruce Thom, said Bondi was ''very resilient'' because its sand remained inside the bay during storms and was not lost to the sea. But in the meantime, coastal land was particularly vulnerable to further storms because there was less sand to buffer it. The images dont surprise anyone with a passing local knowledge.
