Anemone Flat sits on the sheltered western side of South Solitary Island near the Boulder Walls, a shallow patch of reef in 6 to 14 m thickly carpeted with sea anemones and the resident clownfish that make their home among them — a smaller-scale but easily accessible echo of the far more extensive anemone beds found at Elbow Cave on North Solitary Island further north. Because the site rarely exceeds 14 m, it allows unusually long, relaxed bottom times and is regularly used by Jetty Dive Centre as an easy second or third dive once the day's grey nurse shark objectives at Manta Arch or Shark Gutters have been met. Several clownfish species share the anemone beds here, giving photographers plenty of subject variety within a small area, while surrounding sections of reef support the usual dense South Solitary Island fish population: blue groper, resident wrasse, small schooling reef fish and the crayfish and nudibranchs typical of the island's boulder terrain.

Turtles are commonly seen resting nearby, taking advantage of the same shelter that makes the site comfortable for divers. Anemone Flat's shallow depth and negligible current make it one of the more forgiving sites at South Solitary Island, suitable for less experienced divers and for extending a day's bottom time after a deeper morning dive, and its combination of colour and ease has made it a regular request among Jetty Dive Centre's repeat customers. It is not marketed with the same fanfare as Manta Arch, but for unhurried macro photography and a relaxed finish to a day at the islands, it is one of the more consistently enjoyable dives in the group.

Jetty Dive Centre departs from the public floating pontoon wharf in Coffs Harbour boat harbour, opposite the Attitude Burgers building. It is roughly a 30-40 minute run out to South Solitary Island, 8 km offshore.

South Solitary Island sits in open water 8 km off Coffs Harbour; trips need under about 1.5-2 m swell. Visibility here is usually the best in the marine park given the distance from any river mouth. Winter (May-Oct) is the peak grey nurse shark season; summer (Nov-Apr) brings tropical fish, manta rays and leopard sharks.

Descend onto the shallow flat at 6-8 m, spend an unhurried dive working through the anemone beds looking for the different clownfish species present, and extend the safety stop given the shallow average depth.

Jetty Dive Centre includes Anemone Flat as a shallow, easy option on the sheltered western side of South Solitary Island, often for a second or third dive of the day.
