Coastal Homes Under Threat

By Ironbark Homes

Australia is an island continent with 80 percent of its 22 million people living on the coast, but combating rising sea levels causes disagreement amongst stakeholders.

Australian authorities are split on adopting a policy of retreat or defend against rising seas.

Those opposed to defending the coast argue seawalls and breakwaters often see the beach lost to a stone structure, prevent the shoreline from naturally adapting to changing ocean conditions, and move the problem further along the coast.

In Sydney, there is little chance of retreat given the high coastal population. A sea level rise of just 20 cms would see some beachs recede by 110 meters (361 feet) causing hundreds of millions of dollars in damages.

Sand pumping may help some homes, but in other places the local council has a policy of buying threatened homes, bulldozing them and building protective sand dunes.
