Collaroy Storm-damaged Homes secured by Anchor Security
It’s been over 50 years since the Narrabeen community has been impacted by water in this way.
The Anchor Security team responded within hours, and has been working around the clock since with a deployment of half a dozen officers security staff across an area of 1.2kms.
On Saturday, professor Ian Turner, director of the UNSW Water Research Laboratory, was at the scene.
He had this to say to Business Insider: “Turner estimates that 450,000 cubic metres of sand was stripped from the beach — that’s 150 cubic metres of sand for every one metre across the beach, gone, and the equivalent of 180 Olympic swimming pools, or roughly two shiploads from the world’s largest LNG carriers.”
While dangerous conditions prevented researchers getting detailed data, they have been able to get an idea of the extent of the damage.
Here’s a look at the data recorded in recent days.
B. is a reading from June 6, which shows the beach width at 90 metres.
Anchor Security asks that the public respects the signposts that are being deployed by Northern Beaches Council, after many sightseers disregarded the danger signs being posted in unstable areas and crossed barriers and moved fencing to take selfies.
