Yacaaba Head forms the northern arm of the Port Stephens entrance, facing Tomaree Head across the harbour mouth from the Hawks Nest side, and its fringing rocky reef offers a less-dived alternative to the well-established sites clustered around Nelson Bay on the southern shore. The headland is a well-known bushwalking destination with a track to its summit, but the underwater side of Yacaaba sees comparatively little dedicated dive traffic, reflecting both its greater distance from the main Nelson Bay dive centres and its more exposed, tidally-influenced position right at the harbour mouth. Marine life follows the general Port Stephens temperate pattern, with the reef supporting typical fish and invertebrate species in a moderate depth range broadly comparable to the area's other headland sites.

Because the site sits at the confluence of ocean swell and the tidal flow in and out of Port Stephens, conditions here can be more variable and changeable than at the sheltered inner-harbour sites like Fly Point, and a calm day with a favourable tide is needed for either the shore-entry option or a comfortable boat dive. Yacaaba Head is best regarded as an occasional variation for local divers and operators looking to explore beyond the standard Nelson Bay rotation, rather than a site with the established reputation or documentation of Fly Point, Halifax Park or the Broughton Island group, and visiting divers should treat any specific details here as indicative rather than confirmed. Anyone drawn to it mainly for the walk to the summit should treat a dive here as a pleasant bonus rather than the main reason for the trip.

Yacaaba Head is reached via Winda Woppa Road from Hawks Nest, with a walking track leading to the headland. A rock entry is possible on very calm days for experienced divers, though most diving here is by boat from Nelson Bay, crossing the harbour entrance to the northern side, a run of around 20-30 minutes.

Yacaaba Head sits at the harbour entrance and experiences tidal flow in addition to ocean swell exposure — best dived on a calm day around slack tide; conditions can change quickly given the site's exposed position opposite Tomaree Head.

Enter from the headland rocks on a very calm day or from a boat mooring off the point, working the fringing reef at 6-20 m for typical Port Stephens temperate reef species, being mindful of tidal flow given the site's position at the harbour entrance.

Occasionally included by Nelson Bay operators as an alternative to the more heavily dived southern-side sites; more commonly dived by private boat.
