Tourism operators and local Reef industry worked through the night during the most remarkable spawning event on the planet, learning cutting-edge coral restoration techniques to help boost healthy coral numbers.

The annual coral spawning event, triggered by the November full moon, sees the Great Barrier Reef’s magnificent corals burst into life in an underwater ‘snowstorm’ by releasing trillions of eggs and sperm into the water in a mass breeding phenomenon, which Sir David Attenborough describes as “one of the greatest of all natural spectacles”.

“None of the Reef’s residents would be here without one truly extraordinary event,” the esteemed documentary-maker and conservationist commented.

“It occurs just once a year and is one of the greatest of all natural spectacles. It wasn’t until the 1980s that scientists discovered it, here on the Great Barrier Reef.
