Parts of the Great Barrier Reef’s outer reefs can form a natural barrier to coastal recession, thus protecting urban centres.
Coral bleaching on the Great Barrier Reef could lead to increased vulnerability of Queensland coastal cities and towns, and not only through its impacts on the tourism industry.
Mud oysters played a largely unappreciated part in Australia’s history.
In colonial times Australia's waters were teeming with mud oysters that provided food, cement, and cleaned the oceans. Now a 20-hectare man-made reef aims to restore some of their former glory.
