Coral spawning, Great Barrier Reef

RESOLUTION: Learn more about Australia’s unique environment

Get out on the Great Barrier Reef and witness one of the world’s greatest wonders – the planet’s largest synchronised coral spawning event (it’s like a gigantic underwater snowstorm). Once a year, corals release eggs and sperm into the water at the same time. Your best chance of seeing it is by taking a live-aboard dive boat (prodive.com.au) from Cairns, booking around the predicted date. Rather stay on land? The best spot is Lady Elliot Island. ladyelliot.com.au
