What not to do at the Great Barrier Reef?
What not to do at the Great Barrier Reef? Take care when diving and snorkelling Be aware of where your fins are and avoid touching anything with them. Don't rest or stand on coral. If you must stand up, make sure it is on sand or use rest stations. Observe animals rather than handling them directly, and avoid blocking the path of free swimming animals.
When not to visit the Great Barrier Reef?
The Great Barrier Reef is also prone to thunderstorms and the occasional cyclone. If you want reliably good underwater visibility, summer might not be the best time as rain and storms can cause the water to become murky. It's not all bad though.
What should you do if you accidentally step on coral while snorkeling?
Flush the wound with a half-strength solution of hydrogen peroxide in water. Rinse again with water. Apply a thin layer of antiseptic ointment, and cover the wound with a dry, sterile and non-adherent dressing. If you have no ointment or dressing, you can leave the wound open.
