Palm Beach, or better known as ‘Palmy’ to the locals, is one of the most vulnerable Gold Coast beaches to the threat of coastal erosion. After years of investigating an appropriate solution, the City has developed the Palm Beach Shoreline Project; which is a two phase plan to provide ongoing coastal protection of the beach and beachfront infrastructure. Phase 1 consisted of beach nourishment. This was completed in September 2017.
For Phase two, the City will be constructing an artificial reef from May to October 2019. The artificial reef will be positioned approximately 270 metres offshore from Nineteenth Avenue in Palm Beach between the beach and the existing natural reef; and will be constructed out of rock boulders. This innovative underwater structure is required to enhance the ability of Palm Beach to withstand the threat of coastal erosion.
The artificial reef will work by influencing the surrounding currents and waves to act in a way that creates a build-up of sand around the structure. And for all you surfers out there, never fear, surf amenity has been considered in the design process – thanks to the requirements in the City’s Surf Management Plan.
Much research has gone into the design of the artificial reef including computer modelling, wave tank testing and real-life coastal data capture including wave data, aerial photography and analysis of over 50 years survey data to see how the beach behaves not just above the water line but underneath the water too!

What’s the latest… August 2018 update
After a lengthy search, the City has selected a marine construction expert to build the artificial reef. Following Council endorsement in late August 2018, the construction of the artificial reef will commence in May 2019.
