2021 $1 The Great Barrier Reef PNC

The Great Barrier Reef is arguably Australia’s most prized environmental treasure, inscribed on the UNESCO World Heritage List in 1981. This highly complex natural ecosystem covers 344,400 square kilometres and runs from near the tip of Queensland’s east coast to just north of Bundaberg at its south. It is the largest coral reef system in the world - a mosaic of more than 3,000 individual coral reefs and hundreds of continental islands and coral cays. While the reef itself is a living architecture of some 600 species of soft and hard corals, It Is also home to a great abundance of marine life.
