Dive tips

  • Follow the local guide’s site- and tide-specific briefing.
  • Agree a maximum depth within certification limits; the published site range is 10–30 m.
  • Maintain neutral buoyancy and avoid contact with coral, artificial structures and the seabed.
  • Descend as a controlled team in blue water, maintain the planned maximum depth and reserve gas for an open-water ascent and safety stop.
  • Treat wildlife encounters as possible, never guaranteed, and give animals space.

Underwater photography

Wide-angle equipment suits the reef structure and larger marine life. Set exposure before entering current, keep the rig streamlined and secured, and prioritise depth, gas, buoyancy and buddy contact over the photograph.
