Heron Island

• Dive within your limits: Many sites are shallow, but currents can build when tides run. Treat drift dives and exposed reef edges as a step up.
• Surface signaling is not optional: Carry an SMB and whistle. If you separate from the group, signal early.
• Follow the 24-hour no-fly rule: Do not scuba dive within 24 hours of a helicopter or onward airline flight.
• Night dive requirements: Expect experience minimums and an orientation dive before booking a night dive.
• Channel caution: Snorkelers are advised to avoid the channel during daytime boat operations. Divers should also surface with awareness of boat lanes and current.

Heron Island is far offshore, so medical response is coordinated with on-island staff and mainland services.

• On-island support: Dive staff are trained in diving first aid, and the resort can coordinate urgent response.
• Evacuation reality: Serious issues may require evacuation to the mainland by boat or helicopter, depending on weather.
• Before you go: If you have any medical conditions, medications, or are unsure about fitness to dive under Australian standards (AS 4005.1), arrange a dive medical on the mainland before traveling.

Heron Island sits inside the Great Barrier Reef Marine Park and adjacent protected areas.

• Look, do not touch: Avoid touching coral, turtles, rays, or any marine life. Do not chase animals for photos.
• Buoyancy and fin control: Most reef damage comes from fins. Stay off the bottom, especially in shallow coral gardens.
• Reef-safe sunscreen: Choose products without reef-harmful ingredients and use physical sun protection (rash guards, hats) first.
• Use moorings and follow zoning: Boat operators select sites with moorings and appropriate zones. Respect no-anchoring and no-take rules.
• Turtle and seabird etiquette: Keep beaches dark during hatchling season and follow any ranger or resort guidance around nesting areas.
