Green Point is the sandstone headland that closes the northern end of Camp Cove and separates it from Lady Bay, and it gives the Camp Cove dive its structure and depth. Diving north from the beach along the reef edge, the sand at 3–4 m gives way to a rock shelf with quite large overhangs and even small caves at only 2.5–3 m, then a reef edge dropping to sand at 6–7 m, and off the point itself a field of boulders where the bottom 'drops dramatically' and depths of 15–19 m are possible for those who follow it out. The offshore reef can be crossed at its southern end back to the headland, so several routes are available for a 50–60 minute dive.

Fish life is better than the beach: luderick, sea pike, yellowtail, blackfish, velvetfish and blue groper around the boulders, seahorses in the kelp, blue-ringed octopus and cuttlefish in the crevices, and, memorably, a two-metre jewfish encountered in the boulder field. The overhangs shelter Port Jackson sharks in winter and morays at night. The bottom carries the same debris as Camp Cove – champagne bottles and lost valuables from a century of parties on the beach.

Visibility is the weakness: 4–5 m on an average day and 1–2 m after rain. The site is protected from all but northerly swell and is excellent in a southerly wind, which is when the eastern-suburbs schools bring their groups here. The one rule is the same as Camp Cove's and is stated emphatically by Michael McFadyen: 'never, repeat never, ascend from the reef', because boats cut the point constantly – return underwater to the beach.

Green Point suits Open Water divers ready for more than sand, Advanced students on their deep or navigation dives (the boulder field is the only place inside the harbour on this shore to reach 18 m from the beach), and night divers.

As for Camp Cove: Cliff Street, Watsons Bay, with the small car park at the end of Pacific Street (first left off Short Street) closest to Green Point, or the larger Cliff Street car park. Gear up, walk the short distance down to the beach and enter at its south-western end (or the pocket beach beside Green Point). Follow the reef edge north around the headland.

Return the same way or across the reef, and exit onto Camp Cove beach; 50–60 minutes is typical.

Inside South Head the ocean swell is broken; the eastern harbour shore dives are exposed only to wind chop and, in the case of Camp Cove and Green Point, to a north-westerly or northerly blow that puts a short sea onto the beaches. They are at their best in a southerly, which flattens them completely, and on the top of a flood tide when clean ocean water has come in through the Heads (visibility 5–10 m; 15 m on a rare winter day). After heavy rain the harbour is brown for days and the dives are not worth doing.

Boat and ferry traffic is intense on summer weekends and public holidays, when the bays fill with anchored craft; early mornings, weekdays and nights are the times to dive. Green Point is protected from everything except a northerly swell or wind, when the point becomes a wash zone; in a southerly it is excellent.

From the south-western end of Camp Cove follow the reef edge north at 3–4 m past the overhangs and small caves, round the Green Point headland and, in good visibility, jump boulder to boulder down the field to 15 m or more; in poor visibility keep to the reef edge at 6–7 m. Return along the reef or cross from the southern end of the offshore reef back to the headland. Surface only at the beach – never from the reef, because of boat traffic.

Abyss Scuba Diving, Dive 2000 and Frog Dive extend Camp Cove guided dives to Green Point for Open Water and Advanced groups; independent divers regularly.
