Going, going …. this iconic rock will soon be gone!

Published: June 24, 2015

Another of Australia’s iconic rock formations could be about to take a tumble.

A geotechnical assessment has revealed that Wedding Cake Rock at Bundeena south of Sydney is so unstable that it is likely to collapse in the next 10 years.

The news will come as a bit of a shock to the tens of thousands of people who have been photographed on the landmark in recent times. Images of young people doing dangerous looking stunts near the edge have become an Instagram sensation … and it was this craze that prompted the National Parks and Wildlife Service (NPWS) to fence off access a month or two ago..

However, the new study – which included a photographic survey of the underlying rock strata using a drone – found the rock was ‘precariously balancing on the edge of the cliff’.

“Usually when you get a geotechnical assessment, you’ll get a probability of something happening within the next thousand years,” said NPWS regional manager, Gary Dunnett. “To get one back telling you that collapse is likely within a decade is really unusual.”

If, and when, the smooth, white rock collapses, it will certainly not be the first iconic Australian landmark to disappear. In 1990, the famous London Bridge rock formation on Victoria’s Great Ocean Road instantly became London’s Arch after its middle section collapsed.

The NPWS is currently considering putting in a viewing platform at Wedding Cake Rock to allow visitors on the Royal National Park Coast Walk to safely view it.
