The founder of SECORE, an international coral reef conservation non-profit organisation, Dirk Petersen said in 2016 30 percent of coral in the Great Barrier Reef, off north-eastern Australia, died from coral bleaching.
Dr Petersen said with the rapid decline, existing technology for restoring coral was slow and labour intensive.
However, he said the new method could pave the way for large-scale coral reef restoration.
