The corals reefs of Australia and Papua New Guinea cover 19% of the world's total reef area and contain levels of biological diversity approaching the 'hot spots' of the Philippines and Indonesia;
Human pressures on these reefs are lower than in other parts of the world (particularly SE Asia). The reefs of eastern Australia, particularly the Great Barrier Reef (GBR), have a long history of research and monitoring and world leading management;
Fiji, New Caledonia, Vanuatu, Solomon Islands, Samoa and Tuvalu report monitoring data for this report, with data from a broad range of observers (scientists, students, dive guides and communities); Nauru has not conducted recent monitoring;
Status of coral reefs in the Polynesia Mana node is predominantly healthy. There are 6733 km2 of reefs scattered over 347 islands. Most (90%) are healthy, 5% have been destroyed or are at a critical stage and 5% are under threat;Reefs have been degraded around populated areas of Rarotonga (Cook Islands), Tahiti and Moorea (French Polynesia) and South Tarawa (Kiribati);Coral reefs support the livelihoods of Polynesian populations through subsistence fishing in all countries and through tourism and black pearl industries in French
Several urban areas and popular tourist destinations have suffered from pollution from the land, significant fishing pressure, recreational overuse, and alien species. Despite these pressures, many coral reefs in Hawai'i remain in fair to good condition, especially remote reefs; Most MPAs have proven to be highly effective in conserving biodiversity and fisheries
resources. MPA size, habitat quality, and level of protection are the most important success factors, but several MPAs are too small to have significant effects outside their boundaries;
