The federal government's new funding aims to spread the net wide in investigating possible ways to protect the Great Barrier Reef's corals. Winning this battle will require a wide range of weapons.
Some reefs are strong sources of coral larvae.
A new study identifies dozens of individual reefs on the Great Barrier Reef that are especially important for coral larvae dispersal and which could help the entire ecosystem bounce back.
Hundreds of thousands of crown-of-thorns starfish have invaded North Queensland, devastating reefs.
New research has uncovered a whole new way to combat the devastating crown-of-thorns starfish, by decoding the pheromones that they use to communicate.
The Great Barrier Reef’s health has declined in recent years.

Banning fishing helps fish, but it also helps reef recover from cyclones, disease, and coral bleaching.

To fix pollution on the Great Barrier Reef, some farming practices will have to change.
The land may be dry, but Western Australia’s waters are full of life.
The Great Barrier Reef might get all the attention, but what about our western coral reefs? Warmer waters and human impacts mean these reefs are in trouble.
Nutrient runoff is one of the major contributors to crown-of-thorns outbreaks.

Despite 15 years of concerted action by the Australian and Queensland governments the health of the reef is not improving and in fact may be continuing to deteriorate.
During an outbreak, crown-of-thorns starfish can number in the millions and decimate coral reefs.
