Tangalooma Wrecks consists of fifteen deliberately scuttled vessels located 100 metres off the western shore of Moreton Island. Sunk between 1963 and 1984 to create a breakwater, these structures sit in shallow depths ranging from 2 to 12 metres, with an average depth of 5 metres. The site is suitable for beginners, though strong tidal currents require careful planning. Divers and snorkellers can access the site by boat or from the shore. Due to heavy boat and jet ski traffic and the potential for strong currents, diving or snorkelling during slack tide is essential for safety. Guided tours and equipment rental are available locally.

Cherubs Cave at Flinders Reef is an advanced dive site defined by its overhead environment. The site features depths ranging from 14 to 30 metres, with an average of 25 metres. Divers must navigate moderate currents and surge, which can affect visibility, typically between 5 and 20 metres. Access is by boat only, and the site requires careful entry due to potential surf and boat traffic. A torch is essential for exploring the cave sections. Divers should maintain excellent buoyancy and remain aware of the overhead environment and sharp coral structures throughout the 45-minute dive.

Hendersons Rock is a reef and cave site located 4500 metres offshore at Flinders Reef. Divers can explore depths ranging from 12 to 24 metres, with an average depth of 22 metres. The site is suited for intermediate divers due to moderate currents, surge, and variable visibility. Entry is by boat only. Hazards include cold water, potential entanglement, and sharp coral. Divers should maintain high situational awareness when navigating the cave sections. Typical dives last approximately 45 minutes. Water temperatures fluctuate between 20C and 27C throughout the year, necessitating appropriate thermal protection during cooler months.

Gotham City at Flinders Reef is a deep-water site featuring a dramatic pinnacle, wall, and drop-off. The topography ranges from 22 to 37 metres, with an average depth of 30 metres. Due to the open ocean location and strong currents, this site is reserved for advanced divers. Visibility typically fluctuates between 10 and 20 metres. Divers should plan for boat access and consider diving during slack tide to manage the current. Species recorded around this area include wrasses, nudibranchs, and various reef fish. The site is suitable for night diving, with typical dive times around 45 minutes.

The Marietta Dal is an artificial reef wreck located at Flinders Reef, Australia. Resting at depths between 10 and 18 metres with an average of 14 metres, it serves as a manageable wreck dive for beginners. Access is by boat only, with the site situated 3218 metres from shore. Divers should be aware of moderate currents and potential hazards including sharp edges on the wreck structure and the risk of entanglement from fishing lines or debris. Visibility varies significantly, reaching up to 40 metres under optimal conditions. Water temperatures fluctuate between 20C and 27C throughout the year.

The SS Saint Paul is a deep wreck and wall site located 1000 metres off Flinders Reef. Resting at depths between 40 and 43 metres, the site features an overhead environment within the wreck structure. Divers should expect moderate currents and visibility ranging from 7 to 30 metres. Due to the significant depth and potential for nitrogen narcosis, this site is strictly for advanced divers. Boat access is required to reach the location. Divers must maintain precise buoyancy control and monitor air consumption closely throughout the dive. Conditions are most favourable between November and May.

The Cementco Wreck is a dedicated boat dive located at Flinders Reef, Australia. Resting at a depth of 25 metres, this artificial reef structure is suited for intermediate divers. The site features overhead environments that require careful planning and monitoring of nitrogen loading. Divers should be prepared for moderate currents and variable visibility. Species recorded around this area include various wrasses, nudibranchs, and anemonefish. Due to the depth and potential for overhead hazards, this site demands solid buoyancy control. Always check local conditions before departure, as visibility can fluctuate significantly. Boat traffic is a constant consideration at this location.

Pumicestone Passage near Moreton Island offers shallow shore diving and snorkelling within seagrass meadows and artificial reef structures. Depths range from 0 to 5 metres, with an average of 2 metres, making it suitable for beginners. The site is influenced by tidal currents, which can be strong in the channels, so timing dives around slack water is recommended. Visibility typically ranges from 7 to 16 metres. Divers and snorkellers should remain vigilant for boat traffic in this active area. The habitat supports a variety of regional reef fish and invertebrates common to these shallow, sandy, and seagrass-rich environments.
