Why does it matter to create marine sanctuary zone at Bongin Bongin Bay?
Because science tells us that sanctuaries work.
Just down the coast, Cabbage Tree Bay in Manly has been operating for more than two decades. It has provided marine life the opportunity to grow, breed and thrive.
Making Bongin Bongin Bay a marine reserve (a sanctuary) will help closing a big gap in NSW, helping Australia hit its goal of protecting 30% of coastal waters by 2030.
But local marine protection is about more than fish and reefs.
It is about community. It is about protecting the places where children first swim, put on a snorkel, where divers document incredible species, where families spend time by the water and where people come together because they love our saltwater lifestyle and clean neighbourhood.
With over 3,500 new homes being built in Mona Vale soon, around 9,500 new people will be moving in the next few years. More people means more dirty stormwater runoff, trash, trampling on rocks, and over-fishing in our bay. It’s about creating the local Blue Economy, where local businesses and community thrive.
Through eDNA testing, reef surveys and citizen science, we are continuing to discover more about the incredible Bay, cared for by First Nations for millenia. The more we learn, the clearer it becomes: we must act now.
Bongin Bongin Bay must become the marine sanctuary, to sustain our lifestyle, our local economy and this will not happen without giving the Bay status of a sanctuary.
