The Gulf of Carpentaria Marine Park protects a submerged world of steep-sided undersea pinnacles and ancient coral reefs that rise from the shallow seafloor (15–70 m deep). Unlike fringing reefs, these are isolated shoals and patch reefs teeming with large plate corals, soft corals, dense sponge gardens, and abundant fish. The park's remote, near-pristine coastal zone and proximity to the Wellesley Islands make it a vital feeding ground for turtles, seabirds, and sea snakes. This is wild, open-water snorkeling — a true expedition for those seeking untouched reef ecosystems.
