Black Rock (Batemans Bay dive site)

Moderate risk: Ocean swells on exposed sections

Swells can create breaking waves over submerged rocky ridges, particularly at sites like Garden Bay and Pretty Point Bay during easterly winds.

Moderate risk: Jagged rock entry

Access to the Pot requires crossing jagged rocks which can be sharp and slippery; high tide is recommended for easier entry.

Moderate risk: Ocean swells

Exposed to ocean swells from the east; conditions can become unsafe quickly in easterly winds or rising swell.

Moderate risk: Boat traffic

Black Rock is a boat-accessed site near the Batemans Bay channel. Vessels may pass overhead — surface awareness and a dive flag are essential.

Moderate risk: Shallow caves and overhangs

A large cave under Black Rock houses wobbegong sharks and Port Jackson sharks. Entry can silt up easily and may present entanglement risk in confined spaces.

Low risk: Sharp rocks and urchins

Jagged rocky shorelines and abundant black-spined sea urchins in crevices require care when entering and exiting the water, especially at Guerilla Bay and Barlings Island.

Low risk: Strong currents and outgoing tides

Tidal movement through gutters and around headlands can create strong currents; the pot at Guerilla Bay and gutters in Mosquito Bay are affected.

Low risk: Tidal changes

The Pot is best snorkelled at high tide; at lower tides the water depth drops significantly and rock crossings become more hazardous.

Low risk: Outgoing tide current

A north-to-south current can develop on an outgoing tide, creating a drift-dive effect that may carry snorkellers away from the rock. Strongest during spring tides.

Low risk: Depth and vertical drop-offs

The reef drops steeply from the surface to 15–20 metres on the eastern and southern sides. Snorkellers should be confident in deep water and avoid sudden descents.
