The Bolwarra/V-Wall shore dive at Nambucca Heads is a low-key, rarely dived option along the rock training wall that channels the Nambucca River out to sea — a site known to locals more for the colourful hand-painted rocks that line the walking track above the water than for its underwater profile. As a dive site it is modest: a shallow rock face dropping to around ten metres at most, subject to the tidal push and pull of the river mouth and to reduced visibility whenever the river is running with rain-darkened, tannin-stained fresh water sitting over the seawater. On a calm day with a making tide, though, it offers an easy, current-manageable shore dive along a structure that supports typical mid-north-coast estuarine-influenced reef life, without needing a boat or any real planning.

This is very much a local, opportunistic dive rather than a destination in its own right, and it sees little traffic from visiting divers who are, understandably, drawn to Fish Rock and the other boat sites further south. It is best thought of as a convenient training or exploratory dive for anyone staying in Nambucca Heads who wants to get in the water without travelling to South West Rocks, or as a curiosity dive tied to the well-known V-Wall art walk above. Divers should treat the tidal current with respect, since river-mouth training walls can generate a surprisingly strong outflow on a big tide, and should not expect the clarity or marine-life density of the area's better-known sites.

From Nambucca Heads township, follow signs to the Nambucca Headland/V-Wall and park at the reserve beside the river mouth training wall. Carry gear a short distance over sand or rock to enter alongside the wall, timing the dive around the tide — an outgoing river current can run past the wall mouth, so slack or a making tide is preferred for an easier, clearer dive.

A river-mouth site affected by tidal flow and river outflow — visibility is often reduced by tannin-stained fresh water and sediment, especially after rain, and improves on a making tide with settled weather. Best dived on the smaller half of the tide to minimise current along the wall.

Enter beside the training wall at low or slack tide and follow the rock face out toward the river mouth, staying shallow (under 10 m) and turning back well before any noticeable outgoing current builds; this is a casual, low-key dive rather than one with a set circuit.

No dedicated Nambucca dive operator; dived independently by local and passing divers, sometimes with guidance from South West Rocks or Coffs Harbour operators.
