Cairns Great Barrier Reef

Coral Spawning Night Dive & Snorkel - 2018 Dates to be determined

Once a year only, for a few nights in late spring or early summer, the Great Barrier Reef turns on a spectacular and sexy festival. On these nights many corals spawn in a mass synchronised event, unlike elsewhere in the animal kingdom and itshappening right here on the Great Barrier Reef! Tusa 6 provides fun and informative trips for certified divers to watch this phenomenal event and take place, and you can get involved!

What night will it happen?

Linked to the phases of the moon, the most common timing is 3 – 5 days after the full moon in late spring/early summer. There are many factors involved including minimal tidal movement, water temperature and light. Although there are no guarantees of the exact night of the coral spawning, experts can predict the spawning usually a month prior.

In 2017, we witnessed a split-spawning even between November & December. We ran 2 nights in November & 1 night in December and are excited to say we saw the coral spawn on both occasions. We’re looking forward to 2018 coral spawning events!
