Cape Byron Marine Park extends from the Brunswick River to Lennox Head. Marine life includes many species of dolphins, seabirds, turtles, fish, seaweeds and invertebrates such as sponges, corals and anemones. Threatened marine species that occur in the Cape Byron Marine Park include little terns, grey nurse sharks and sea turtles. Humpback whales travel through the park on their annual migration. Sites within the marine park that have been identified as particularly culturally significant to Indigenous people include Julian Rocks, Cocked Hat Rocks, Cape Byron and the beaches around Broken Head.
