Hayden's Rock is a modestly documented reef and rock formation near Forster that appears in local site listings without the detailed write-up given to the area's headline dives. As with several similarly under-documented sites in this cluster, it likely serves as a secondary option in Forster Dive Centre's rotation — useful for varying a multi-dive itinerary, for club dives, or for divers who have already done the main sites and want to see more of what the area offers, rather than being actively promoted to first-time visitors. The name suggests a personal association, common on this coast where many minor sites carry the names of local divers, fishermen or boat owners who first identified or frequented them.

Depths and topography can reasonably be assumed to sit within the same general range as the area's other inshore reef sites, given the shared geology and depth profile of the Forster nearshore zone, but specific published detail on marine life, exact coordinates or a set dive route was not found in the sources consulted for this report. Treat the details above as a starting point rather than a guarantee of what any particular dive will show.

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 onto the rock formation and work its structure at 10-20 m in typical Forster reef style, exploring ledges and crevices for resident fish and invertebrates.
