Watanabe Bommie is a pinnacle, wall, and reef site located 40 kilometres offshore in the Coral Sea. The topography features a wall that drops from 20 metres into significant depths, requiring careful monitoring of depth gauges. Divers experience mild currents and consistent visibility of 30 metres. The site is accessible only by boat. While the pinnacle offers a variety of reef habitats, divers should remain above 20 metres to keep the dive within manageable recreational limits. The environment supports a range of reef fish and invertebrates typical of the region. Due to the significant drop-offs, this site is best suited for experienced divers comfortable with deep water.

Herald Surprise is a wall and reef site in the Coral Sea, offering depths reaching 70 metres. The vertical wall structure is colonised by soft corals, sponges, and sea fans. Divers experience consistent visibility of 30 metres, though the remote, exposed location means conditions can be unpredictable. This site is suited for advanced divers capable of managing decompression dives and strong currents. Access is by boat only. Divers should carry a reef hook for use along deeper sections of the wall and confirm decompression gas availability with their operator before departure. The site supports a variety of reef fish and invertebrates typical of the region.

Rock Arch at Flinders Reef offers a complex topography featuring a dramatic wall, a cave system, and reef structures. Divers can explore depths ranging from 5 to 40 metres, with an average depth of 25 metres. The site is accessible only by boat and is suited for advanced divers due to the overhead cave environment and significant depth. Visibility is high, typically between 30 and 60 metres, though currents remain mild. The reef supports a variety of reef fish and invertebrates throughout the structure. Divers should carry a torch for the cave sections and monitor air consumption closely given the depth and overhead hazards.
