Curtin Artificial Reef, located off Moreton Island, consists of purpose-built structures resting at depths between 12 and 30 metres. This site is primarily a boat dive, though it can be accessed via drift diving due to strong tidal currents. Divers should plan their visit for slack water, approximately 30 minutes on either side of high tide, to manage the challenging conditions. Visibility typically ranges from 6 to 10 metres. Hazards include potential entanglement in discarded fishing tackle, boat traffic, and the presence of stonefish, demon stingers, and leaf scorpionfish on the wrecks. Species recorded around this area include wobbegongs, sea turtles, various butterflyfish, and wrasses.

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.

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.

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.

North East Reef at Mud Island is a shallow site ranging from 0 to 5 metres in depth. As an inner bay location, conditions are tidal, and a moderate current is common. Visibility fluctuates between 1 and 11 metres, making timing essential for the best experience. The site is accessible only by boat, and snorkelers must remain vigilant due to regular boat traffic in the area. The reef environment supports a variety of reef fish and invertebrates typical of the region. Always deploy a surface marker buoy before ascending to ensure visibility to passing vessels. The island is known for high mosquito activity.
