About Boarfish Reef

This is an extension of "Lonsdale Wall Reef", that was discovered in 1982 by a group of local divers after accidently drifting over this reef. As the name says, this reef is rich in Boarfish and has a large variety of different corals. The bottom consists of sand bommies and many rocks.

Dive Site Hazards

  • Bubble Trapping Under Overhangs — Rock overhangs can trap exhaled bubbles, reducing visibility and causing disorientation.

  • Reflected Surge Patterns — Surge reflecting off rock faces can create irregular and unpredictable water movement.

  • Current Funnel Effect — Narrow gaps between rocks can accelerate water flow unexpectedly.

  • Eddy Pull-Off Zones — Eddies behind structures can pull divers away from the main drift line.

  • Delayed Surface Pickup — Strong current can exceed surface tracking assumptions, delaying boat pickup.

  • Vertical Current Shear — Currents may vary by depth, causing vertical separation even when divers stay together.

  • Hidden Depth Variations — Complex reef topography can conceal depth changes, leading to unintended profile variations.

  • Distraction from Marine Activity — High fish activity can distract divers and delay depth or gas awareness.

  • Rapid Surge Direction Changes — Surge near reef structures can reverse direction quickly, pushing divers sideways into unexpected areas.

  • Unstable Visual Ascents — Relying on wall visuals can destabilise ascents.

  • Gradual Depth Creep — Lack of visual bottom reference can cause unnoticed descent.

  • Unsignalled Downcurrents — Downcurrents can form without visible indicators.
