Marley Point North is the northern companion to Marley Point, about 5 km south of Port Hacking on the Royal National Park coast, and McFadyen rates it an excellent dive. The reef is narrow here, which dictates how and when it can be dived: the boat anchors in 10–12 m close to shore and must hang away from the rock platform, so only north-west to westerly winds will do, and anything from the north-east to south-east rules it out. In practice it is a winter site.

From the anchor, the reef runs north-east to sand at about 18 m, with deeper sandy areas dropping to over 21 m and the reef edge at about 20 m. Closer in, the rock platform extends underwater at 8–10 m and is cut by swim-throughs and gullies, before curving west back towards the anchorage. The sand holds Port Jackson sharks, rays, angelsharks and possibly stargazers.

On the reef are one-spot pullers, black reef leatherjackets, several species of wrasse and bream, while the shallows swarm with yellowtail, seapike, pomfret, luderick and silver sweep, with large silver drummer and even kingfish. Sponges decorate the deeper sections. Visibility is usually better than the Sydney average.

The combination of a sand-edge route and a shallow return through swim-throughs makes for a varied, relaxed dive with plenty of no-decompression time. There is no charter, so it is a private-boat or St George Scuba Club dive. It suits Open Water divers with boat experience on the right winter day, and it pairs naturally with Marley Point.

Boat only. Launch in Port Hacking (Gunnamatta Bay, Lilli Pilli or Bundeena), run out through the entrance and south along the Royal National Park cliffs about 5 km – 15–20 minutes. McFadyen's GPS for the southern part of the site is 34° 06.7397' S 151° 09.1499' E.

Anchor close to shore in 10–12 m, and only in north-west to westerly winds so that the boat hangs away from the rock platform – the reef is narrow here.

The site needs north-west to westerly winds so the boat hangs away from the rock platform; any wind from north-east to south-east rules it out, and swell from those directions makes the close-in anchorage dangerous. It is essentially a winter site on calm westerly days. Visibility is typically better than Sydney average – McFadyen considers 12 m below average here.

A strong north-easter makes the trip back to Port Hacking rough.

Head north-east from the anchor to the sand at about 18 m, follow the sand edge north for about 20 minutes, then come back through the shallows over the rock platform (8–10 m) with its swim-throughs and gullies as it curves west towards the anchor. Explore the deeper reef afterwards if gas allows.

No regular charter – private boat or dive-club (St George Scuba Club) only; no charter boat currently operates out of Port Hacking.
