Artificial reefs are utilised world-wide to create new, high quality habitat for marine life and enhance fishing opportunities. In NSW, the DPIRD artificial reefs program facilitates the building of large-scale offshore artificial reefs for recreational fishers to enjoy. These specially designed artificial reefs increase productivity of marine life and increase biodiversity in the marine environment. They also provide new habitat for a range of species, including iconic recreationally targeted fish such as kingfish and snapper.
In October 2023, artificial reefs were constructed off the Forster and Terrigal coasts. These are the latest of 11 offshore artificial reefs deployed across the State’s coastline since 2011, spanning from Merimbula to Tweed Heads. The reef at each location is comprised of two steel towers of around 50 tonnes in weight, rising 12 metres from the ocean floor with footprints of 16 x 16 metres.
The reefs are engineered to withstand enormous coastal storms and are designed to last many decades, ensuring that the benefits from today's investment can be enjoyed by future generations of recreational fishers. Purpose-built artificial reef designs like these are very effective thanks to their ability to divert currents and create eddies and upwellings. This concentrates plankton and small fish up into the water column while the structure is also used for protection and settlement. The reefs provide a cost-effective method to improve sustainable recreational fishing opportunities and drive economic growth through enhanced fishing tourism, while also providing significant ecological and productivity benefits.
