Little Seal Rock sits alongside its larger neighbour off Sugarloaf Point and offers a more approachable, shallower alternative within the same grey nurse shark critical habitat area — its maximum depth of around 20 metres and complex rock reef structure make it well suited to a full circumnavigation of the island in a single dive, something the deeper, more spread-out Big Seal Rock doesn't as easily allow. Local operators also dive it as a 'quadrant' site, focusing on one section of the island's structure at a time (12-20 metres) for a more detailed look at a smaller area, an approach that suits repeat visitors wanting to build a complete picture of the island's marine life across several dives. Grey nurse sharks are a regular sighting here, generally in smaller numbers than the well-known Eastern Gutter aggregation at Big Seal Rock but still a reliable feature of most dives, and bull rays are a particular signature species at this site, often seen resting on the sand or cruising along the reef edge.

Schooling fish move around the complex, current-swept rock structure in good numbers, taking advantage of the nutrients stirred up by the moderate current typical of this exposed headland. Little Seal Rock's combination of manageable depth, genuine structural complexity and reliable marine life makes it an excellent complement to a Big Seal Rock dive on the same trip, and its shallower profile means it is also a reasonable option for divers not quite ready for the full depth range of its larger neighbour.

Boats for the Seal Rocks sites either run the longer distance down from Forster/Tuncurry (about 45-60 minutes) or launch locally from the small boat ramp at Seal Rocks village itself, near Sugarloaf Point, cutting the run to Big and Little Seal Rock down to 10-20 minutes. Seal Rocks is a small, remote settlement reached via Lakes Way/Mungo Brush Road through Myall Lakes National Park; there is no dedicated dive shop in the village itself, so most Seal Rocks charter diving is booked through Forster Dive Centre, with divers sometimes meeting the boat locally rather than travelling from Forster.

Seal Rocks sits on an exposed headland with Sugarloaf Point taking the full force of easterly and south-easterly swell — trips are cancelled in anything beyond about 1.5 m swell, and the site is often diveable when more sheltered locations further north are blown out, or vice versa, so conditions should always be checked specifically for Seal Rocks rather than assumed from Forster. Visibility is typically 15-30 m and can be excellent in settled autumn and winter weather; it drops after the Myall Lakes and Wallis Lake systems discharge following heavy rain. Grey nurse sharks are present at almost any time of year here, with numbers varying seasonally, and the wrecks (Satara, Catterthun) require calm, low-current conditions for safe deep/technical diving.

Descend onto the reef and either work a single quadrant of the island's structure (12-20 m) for a detailed look, or, on a calmer day, plan a full circumnavigation of the island under 20 m, watching for grey nurse sharks, bull rays and the schooling fish that move around the complex rock structure.
