Beneath the waves, along the southern coastline of Australia, there is a reef that many people still do not know about.
It is called the Great Southern Reef.

The water here is cold, so unlike tropical reefs made of corals, the Great Southern Reef is built from rocky reefs covered in kelp. Kelp is a type of brown seaweed that forms large underwater forests, which are home to many marine creatures such as fish, molluscs and crustaceans.
