Mobula Wall is a drift dive located on the Far Northern Outer Reefs in Australia. The site features a wall structure that descends from the shallows to a base depth of 40 metres. Divers can expect visibility between 10 and 30 metres. The site is suitable for intermediate divers who are comfortable managing buoyancy and monitoring depth, as mild currents can shift and potentially carry divers deeper than intended. Access is by boat only. The habitat supports a variety of reef fish and invertebrates typical of the region. Divers should be aware of boat traffic and sharp coral when entering or exiting the water.

Cathedral Wall is a remote reef site in the Far Northern Outer Reefs, characterised by a steep wall that drops from 30 metres into deep water. The topography features substantial sea fans attached to the reef face. Divers can expect moderate currents, making this a suitable location for drift diving. Visibility ranges from 15 to 40 metres. Due to the depth and remote location, this site is intended for advanced divers only. A surface marker buoy is essential for safety. Water temperatures fluctuate between 25C and 29C throughout the year. The site supports a variety of reef fish and invertebrates typical of the region.

Southern Small Detached Reef is a technical diving destination in the Far Northern Outer Reefs, characterised by a dramatic wall that drops from 3 metres to 100 metres. The site features shallow reef tops leading to a sheer vertical face. Visibility ranges from 10 to 40 metres, requiring careful depth management to avoid drifting deeper than planned. Currents are generally mild, though they can strengthen near the wall. Access is by boat only, and the site is suited to intermediate divers with strong buoyancy control and awareness. Divers should monitor air supply and ascent rates closely due to the significant depth profile.

Star Reef is a boat-access wall and drift dive located in the Far Northern Outer Reefs. The site features a wall structure that descends from 25 to 50 metres, making it suitable for divers of varying experience levels. Beginners should remain in the shallower sections of the wall, ideally no deeper than 18 metres, to avoid the significant depths found at the base. Conditions are generally mild, though visibility can fluctuate between 10 and 30 metres. Divers will encounter crinoids, which are frequently found anchored to the rocky surfaces of the reef. Due to the depth and drift nature of the site, careful buoyancy control is required.
