Pop singer Toni Childs is preparing to sing underwater to raise money for the Great Barrier Reef.
The underwater concert on the Great Barrier Reef will take place in July, using an underwater bubble helmet to sing underwater, and custom speakers that can play underwater.
Child's hopes to inspire people around the world to invest in restoring not only the Great Barrier Reef, but reef systems around the world.
Childs will be accompanied by a team of scientists and funds from the concert will go towards reef research.
