Coral Reefs

Coral reefs are known as the ‘rainforests’ of the sea because of their rich diversity of life. They cover less than 0.2% of the ocean floor, yet provide a home for around 25% of the oceans species. Coral reefs are formed when hundreds of hard coral colonies grow next to and on top of each other.

Beautiful coral reefs are found in Moreton Bay.Moreton Bay Marine Park is fortunate to have some of the most southern located reef-building corals on the East Coast of Australia. These coral reef communities manage to persist at the extreme limits of their tolerance. Because of the gradients in the Bay, many of the reefs are uniquely distinct from each other.


Threats in the past included coral mining of these reefs, a practice AMCS successfully helped to stop. Current threats to the coral communities include anchor and fishing tackle damage as well as indirect impacts such as pollutants and increased water turbidity from runoff.


  • Try and use natural cleaning products in your home (eg bi-carb soda and vinegar) to reduce nutrients and chemicals going into the bay.
  • Take care when anchoring your boat and try to avoid anchoring in coral rich areas
