This dive site, Lighthouse Bommie, is a beautiful, isolated coral pinnacle situated off Reef 10 within Australia's iconic Great Barrier Reef. This approximately 30-foot (9-meter) diameter bommie rises dramatically from a sandy bottom at 22 meters, culminating in a vibrant crest just 3 meters below the surface. Divers typically navigate by circling the bommie, ascending gradually to observe the ecosystem's changing colors and inhabitants. There is no specific historical record provided for the bommie itself, but its name suggests proximity to a navigational light.
The entire Lighthouse Bommie is a thriving hub of marine biodiversity, richly covered in stunning flora and fauna. Expect to encounter an array of colorful hard and soft corals, providing shelter for numerous species of reef fish. Towards the deeper sections of the bommie, observant divers may spot unique macro life, including the fascinating mantis shrimp. The excellent visibility and vibrant ecosystem create ideal conditions for appreciating the intricate details of smaller reef inhabitants and their environment.
The optimal time to visit Lighthouse Bommie is generally during the dry season, from May to October, when the weather is stable, and water clarity is at its best. Its shallow top at 3 meters makes it an exceptional spot for snorkelers to witness abundant marine life and vibrant corals. Freedivers will also find the full depth range up to 22 meters very appealing for breath-hold exploration. Scuba divers of all experience levels will enjoy this site, but should be mindful of potential mild to moderate currents, which can enhance drift experiences around the bommie.
