Dive Site: Manta Bommie

About Manta Bommie

Manta Bommie is consistently ranked among Australia's top dive sites, located a short boat ride from Point Lookout on North Stradbroke Island. This popular outer-reef cleaning station is famed for its consistent presence of reef manta rays, making it a significant draw for divers and snorkelers. The topography consists of large rock and reef formations rising from the sandy seafloor, forming a 'bommie' that serves as a vital cleaning station for mantas and other pelagic species. Depths at the bommie range from 14 to 20 meters, with the pinnacle reaching 14 to 16 meters and its base extending to 18 to 20 meters, making it accessible for various diver levels. While manta rays are frequently spotted from October to April, the site also hosts a rich variety of marine life year-round. Divers can expect to encounter green and loggerhead turtles, eagle rays, leopard sharks, guitarfish, and diverse reef fish. Seasonal highlights include schooling eagle rays and cownose rays, alongside numerous macro subjects like nudibranchs and flatworms. Diving Manta Bommie typically involves a guided boat operation, approaching the site as a patient mid-depth dive where divers maintain position around the bommie. The experience centers on observing mantas and other large animals as they interact with the cleaning station, providing exceptional wide-angle photography opportunities.

Conditions & Currents

Manta Bommie is an outer-reef site, meaning it is more exposed and weather-sensitive compared to sheltered lagoon sites. Currents here can be moderate to strong, necessitating comfort with blue-water style entries and exposed boat pickups. Surge may also be present, especially in less settled conditions. Divers should be prepared to hold position around the cleaning station without crowding wildlife, emphasizing good buoyancy control and respectful interaction. Visibility averages around 20 meters but can fluctuate based on conditions. While thermoclines are not specifically mentioned, water temperatures vary seasonally, influencing exposure suit choice. This site is best enjoyed when outer-reef conditions are settled, and divers should consult local operators for daily conditions.

Dive profile & how the dive runs

Dives at Manta Bommie typically commence with a boat entry, usually a blue-water entry given its outer-reef location. The dive objective is to reach the bommie structure, which rises from a sandy base at 18-20 meters to a pinnacle at 14-16 meters. Divers then patiently hold position around the bommie, allowing manta rays and other large pelagic species to approach the cleaning station. The dive is usually conducted as a patient, mid-depth experience, focusing on observation rather than extensive swimming. The turn point is determined by air consumption or bottom time, with the safety stop conducted in the shallower water surrounding the bommie or during the ascent, before an exposed boat pickup.

Underwater photography

Manta Bommie is an exceptional site for wide-angle photography, especially to capture the majestic manta rays and the vibrant blue-water coral scenery. A wide-angle lens is essential for documenting the mantas and the extensive reef formations. Strobes are beneficial to bring out the colors of the corals and marine life, even in clear conditions. Focus on good buoyancy to maintain position around the cleaning station without disturbing the animals or kicking up sand. When photographing mantas, practice patience and respect; avoid chasing them or swimming onto the cleaning station, allowing them to approach naturally for the best shots.

Getting there & logistics

Manta Bommie is accessed via a short boat ride from Point Lookout on North Stradbroke Island, referred to locally as 'Straddie'. Getting to Straddie is straightforward, with a 25-minute ferry ride available from Cleveland, located south of Brisbane. Brisbane International Airport is approximately a 45-minute drive from Cleveland, providing convenient access for international and domestic travelers. Diving operations often run guided recreational boat dives almost daily from local dive centers, with options for standard two-dive trips or longer dives for technical divers. Manta Bommie is typically visited as a dedicated boat dive, often combined with other local sites.

Safety & environment

Diving at Manta Bommie requires adherence to local safety protocols due to its exposed outer-reef location and potential for moderate currents and surge. Divers should be comfortable with blue-water entries and exposed boat pickups. It's crucial to stay still around cleaning stations to avoid stressing marine life, particularly manta rays. The nearest recompression chamber and medical facilities would be located on mainland Brisbane, necessitating robust evacuation procedures in case of an emergency. Divers are strongly advised to have comprehensive dive insurance covering medical emergencies and evacuation. Always dive with a reputable operator and follow their briefings and guidelines, as Manta Bommie sits within protected Great Barrier Reef management zones, requiring low-impact behavior.
