Great Barrier Reef
GREAT BARRIER REEF, a vast coral reef extending for 1200 m. along the north-east coast of Australia (q.v.). The channel within it is protected from heavy seas by the reef, and is a valuable route of communication for coasting steamers. The reef itself is also traversed by a number of navigable passages.
