The Wallabi Group in the Abrolhos Islands offers diverse underwater topography including reefs, walls, wrecks, and drift sites. Divers can explore depths ranging from 5 to 30 metres with visibility typically between 15 and 30 metres. The site is accessible only by boat, located 60 kilometres from the shore. Conditions feature moderate currents, though some areas experience stronger flows. Due to the presence of wreck sites, overhead environments, and sharp coral, intermediate skill levels are required. Divers should be prepared for boat traffic and potential entanglement hazards. Water temperatures remain stable between 21 and 24 degrees Celsius throughout the year, supported by the influence of the Leeuwin Current.

East Wallabi Island features a mix of reef and seagrass habitats suitable for beginner divers. The site ranges from shallow depths to 12 metres, with an average of 4 metres. Visibility typically spans 10 to 30 metres, though conditions vary with swell and wind. Access is possible by both shore and boat. Divers should remain aware of variable currents, surge near the reef, and local boat traffic. Species recorded around this area include baldchin groper, blue-barred parrotfish, various wrasses, elongate clam, western king wrasse, butterflyfish species, sea slugs, Clark's anemonefish, and sea stars. Humpback whales migrate through the region between June and November.

The Wallabi Group in the Abrolhos Islands offers a diverse underwater environment featuring reef, wreck, and drift diving. Depths range from 3 to 35 metres, with an average of 15 metres. The site is influenced by the Leeuwin Current, which typically flows at 1 knot, providing conditions suitable for drift diving. Visibility varies between 12 and 30 metres. Access is by boat only, and the site is best suited for intermediate divers due to strong currents and potential surge. Hazards include boat traffic from local fishing operations, sharp coral, and deep sections. Divers should use a surface marker buoy on all ascents and plan dives around the tidal cycle.

Morning Reef in the Wallabi Group offers shallow diving at a consistent depth of 6 metres. With visibility reaching 30 metres, the reef structure is clearly visible from the surface. The site is suitable for beginners, though divers must be prepared for moderate currents. Access is by boat only, and divers should remain aware of boat traffic when surfacing. Due to the presence of strong currents, it is recommended to hold onto the boat or a guide line before descending. Always use a surface marker buoy upon ascent. The site supports night diving and is serviced by local boat charters and guided tours.

The Batavia Shipwreck is a historic site located on the seaward side of Morning Reef in the Wallabi Group. Resting in shallow depths of 4 to 6 metres, the wreck is exposed to open ocean swell and wind, which can create significant surge and moderate currents. Due to these conditions, the site is suited for advanced divers who possess strong buoyancy control. Visibility typically ranges from 10 to 30 metres. Access is by boat only, and divers should remain cautious of sharp coral and boat traffic. Guided charters are recommended to assist with navigation and provide historical context for this exposed location.

Anemone Lump is a pinnacle reef in the Easter Group that rises from a 40-metre base to a shallow top at 8 metres. The site features vertical walls and plate corals that form extensive overhangs. Divers and snorkellers should be aware of moderate currents and visibility that can fluctuate up to 40 metres. Due to the depth range of 4 to 40 metres, this site is suited to intermediate divers with appropriate training. Boat access is required to reach the pinnacle. Lionfish are present at the site, so divers should exercise caution regarding hand placement near ledges and coral structures.
