Little Rock is one of the minor named formations within the broader Seal Rocks reef system, appearing in local dive centre listings alongside the much better documented Big Seal Rock, Little Seal Rock and Statis Rock. As with several of the area's smaller features, detailed independent description of its exact topography and marine life beyond its name and general location is limited, suggesting it functions as a variation site used by Forster Dive Centre to spread diver traffic or add variety for repeat visitors rather than a site with its own dedicated marketing. Its position within the general Seal Rocks reef complex means it likely shares much of the same underlying character — rock and gutter structure supporting temperate reef fish and invertebrates, with grey nurse sharks a genuine possibility given their movement throughout the broader area.

This kind of lightly documented, locally known formation is typical of the Seal Rocks area, which operators describe as containing hundreds if not thousands of individual reef patches beyond the handful of named, heavily dived sites. Visiting divers with a specific interest in Little Rock, or planning a longer Seal Rocks stay wanting to see beyond the main attractions, should ask Forster Dive Centre directly for current, first-hand detail on what the site currently offers and how it compares with its better-known neighbours, since confidence in the specific figures given here is necessarily lower than for the primary Seal Rocks dives. As with the area's other minor formations, on-the-day local knowledge from the boat crew will be far more useful than any general description.

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 sits on an exposed headland — trips are cancelled beyond about 1.5 m swell. Visibility is typically 15-30 m in settled weather.

Descend onto the formation and work its structure at 8-20 m, watching for general Seal Rocks reef fauna and the possibility of grey nurse sharks moving between the main aggregation sites nearby.
