“We really didn’t want to build a wall,” says Bob Orth.

But Orth is one of 10 residents of Collaroy, on Sydney’s northern beaches, who have each paid $300,000 to do just that.

And not just any wall. Construction began in December on a seven-metre-high sheer concrete structure below the residents’ properties, which overlook a beach that has become notorious for dramatic erosion every time there is a big storm.
