The Southern Cross University Coral Reef Research Group was established in 2002 and our research includes international research projects on coral reproduction, coral growth and palaeo-environmental changes, effects of pollution on corals, coral bleaching impacts on reefs, and long-term monitoring of coral reef communities.

Corals are foundation species that are essential for coral reef formation, and coral reproduction is a critically important phase of the coral life cycle. Our coral reproduction research includes ongoing projects on the mass coral spawning phenomenon on the Great Barrier Reef and related research on coral spawning at subtropical reefs along Australia's east coast, and international research with colleagues in French Polynesia, New Caledonia, the Maldives and other reef regions.

Professor Peter Harrison is currently leading research teams in the Philippines and the Great Barrier Reef to study coral restoration using millions of coral larvae that settle on reef areas to create new coral populations.

Our research has also demonstrated that essential sexual reproduction processes in corals can be impaired or blocked by a wide range of pollutants and other forms of stress on corals, including: oil pollution, trace metals, elevated nutrients, temperature stress, low salinity and sub-lethal coral bleaching.

Coral bleaching refers to the loss of symbiotic microalgae (zooxanthellae) and their photosynthetic pigments, and bleaching occurs when corals become stressed by extreme temperature and light conditions, by many forms of pollution, and other changes to their natural environment. Our research includes determining the impacts of bleaching on coral survival and reproduction on the Great Barrier Reef and subtropical reefs including Lord Howe Island, where we recorded the first major coral bleaching event in 2010.

Our researchers have monitored the structure and health of coral communities at many reef regions including the Great Barrier Reef, Lord Howe Island, Solitary Islands and other subtropical reefs, French Polynesia, Kuwait, and the Maldives. This monitoring research is providing important information on the resilience of reef communities and their capacity to survive and recover in our increasingly changing world.
