Bennetts Head Bommie is a compact, isolated rock formation off the Forster headland of the same name, running roughly 80 metres in length and rising from the surrounding sand to within eight to ten metres of the surface — shallow enough to make it one of the most relaxed and photography-friendly dives in the Forster rotation. A small cave on the bommie's ocean-facing side gives divers a bit of overhead-environment interest without any real technical demand, easily explored ('noodled around', as local divers describe it) rather than requiring specialist training. Visibility here is regularly excellent, often reaching 30 metres, a product of the site's position away from any river or lake outflow and its relatively exposed, well-flushed location.

The bommie supports a genuinely broad marine life list for its size: shovelnose and bull rays and turtles are seen on the surrounding sand, while the rock itself holds red morwong, eastern blue groper, luderick, surgeonfish, leatherjackets, old wife and boarfish among the reef fish, and a strong population of moray eels, cuttlefish, nudibranchs, shrimp, lobsters and hermit crabs among the invertebrates, all set against a backdrop of anemones, kelp and soft corals. This combination of shallow depth, long possible bottom times, reliable visibility and dense small-scale marine life makes Bennetts Head Bommie one of Forster's best all-round dives for underwater photography and for divers who prefer an unhurried, detail-focused dive over a big-animal chase, and it works well as either a stand-alone outing or a relaxed second dive after a deeper morning at The Pinnacle.

Boats depart from Forster Dive Centre's base at Tuncurry (30 Manning Lane) or the Forster/Tuncurry boat ramp on Wallis Lake, running out through the lake entrance to the open sites. Forster-side sites (Latitude Rock, The Pinnacle, Bennetts Head Bommie) are 10-25 minutes away; Seal Rocks sites are a longer run of roughly 45-60 minutes further south, or reached by launching a boat directly from the Seal Rocks/Sugarloaf Point boat ramp for a much shorter trip.

Forster and Seal Rocks sit on an open, exposed stretch of coast with limited shelter — trips are cancelled in significant easterly swell or strong wind, and operators generally want under 1.5-2 m swell to run safely, especially for the Seal Rocks sites given the longer, more exposed run. Visibility is typically best in autumn and winter (15-30 m) and can drop after East Coast Lows or heavy rain from the Wallis Lake/Myall Lakes catchments. Grey nurse sharks are present through most of the year with the largest aggregations typically reported over the cooler months.

Descend the mooring onto the bommie's shallow top at 8-10 m and circumnavigate its roughly 80 m length, ducking into the small cave on the ocean-facing side, and taking time over the resident invertebrate life given the shallow depth allows an extended bottom time.
