Meet the site
Comboyuro Point, at the north-western tip of Moreton Island, is one of the deeper and more adventurous bay-side dives. marinelife.org.au describes it as a drift along a coffee-rock shelf running parallel to the island, with large boulders, walls, ledges and shallow caves, starting at around 35 m and rising to about 15 m as the shelf approaches the beach. Its position at the northern entrance to Moreton Bay means the water moves strongly with the tide, which brings nutrients and big fish but also makes the dive one for experienced drift divers. The boulders and ledges shelter grey nurse sharks, estuary cod and turtles, and schools of pelagic fish move along the shelf in the current. Wobbegongs rest in the shallow caves. Nigel Marsh groups Comboyuro with The Pines as a deeper coffee-rock alternative on the inner side of the island. The dive is normally run on the incoming tide, when clearer ocean water floods into the bay and the current carries divers from deep to shallow, finishing in a comfortable depth for the safety stop. Because the top of the dive is below 30 m, nitrox or careful gas planning is important, and divers need to be comfortable descending quickly in current and staying together. It is not a regular charter site, so most divers will see it on club trips or special charters. For those with the skills, it offers a genuine big-fish drift within the relative shelter of Moreton Bay. Nearby, the three Bulwer wrecks provide an easy shallow snorkel for non-divers.
