Black Head Reef sits off Blackhead Beach, a surf beach a short distance south of Forster proper, and offers a dual-access option not shared by most of the area's other dive sites: a genuine shore-dive possibility from the headland rocks in calm conditions, alongside the more commonly used boat access for a slightly more complete look at the reef in typical depths of six to eighteen metres. This flexibility makes it a useful site for independent divers without a charter booking, or for a quick, low-commitment dive squeezed in around other activities in the Forster area, though as with any ocean-exposed shore entry it demands genuinely calm conditions and some local knowledge of the safest entry and exit points on the rock platform. Marine life reflects the general Forster-area mix of temperate reef fish and invertebrates, without the specific big-drawcard species (grey nurse sharks, resident turtles) more strongly associated with the purpose-named Latitude Rock or Bennetts Head Bommie sites, though sightings of both are certainly possible given the site's proximity to the broader shark and turtle habitat along this stretch of coast.

Black Head Reef is best thought of as a solid, flexible option rather than a headline destination — useful precisely because it does not require a boat booking, and a reasonable fallback for days when swell rules out the more exposed offshore pinnacles but a protected pocket of the Blackhead headland remains diveable. Checking recent conditions with Forster Dive Centre before planning a shore attempt here is a sensible precaution given the exposed nature of any ocean rock entry.

Blackhead Beach is reached via Blackhead Road south of Forster; park at the beach reserve and carry gear to a rock entry point on the headland for a calm-day shore dive, or join a Forster Dive Centre boat trip departing Tuncurry, a short run of about 15-20 minutes to the site.

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.

Enter from the Blackhead rock platform on a calm day or from a boat mooring, working the reef at 6-18 m for typical Forster-area reef fish and invertebrates, staying within sight of the entry point if diving from shore.
