They have always dreamed of diving Great Barrier Reef since they earned their diving certification in the 1970s.

Corals are marine animals with a symbiotic relationship with algae, which gives corals their color.

In 2015, the Australian and Queensland governments released a grand framework for protecting and managing the reef until 2050. He said climate change, plastic pollution and over-fishing were all contributing to the demise of coral reefs.

Almost three million people visit the Great Barrier Reef each year. "Just this week we announced a world leading research project which will mix warmer surface water with cooler waters from the deep in an effort to reduce the impacts of thermal stress on the Great Barrier Reef to mitigate coral bleaching events. They're getting ready to travel to Australia this month to dive off the reef. This does kill the coral but it … The longer the bleaching, the more likely the coral will die. "This is on the back of announcement last week of a trial on the Great Barrier to identify highly resilient reefs and pilot 're-seeding' to restore coral.".
