AQUATIC AGENDA
When Captain Cook visited, in the 1700s, what we now know as Sydney Harbour, he described abundant oyster reefs, tidal fringes lined with saltmarsh and mangroves, and sandy beaches. Today, more than two and a half centuries later, seawalls dominate the foreshore of the harbour, with oyster reefs long lost and forgotten. Compared to the habitats they have replaced, these seawalls typically support less biodiversity.
