Successive Commonwealth governments • Exmouth over the past 20 years have committed to the 3 creation of a network of marine sanctuaries around Australia. This network of marine sanctuaries will meet the needs of our unique marine life as well as our international obligations to marine conservation. With more sea than land under our government’s care, it’s an important responsibility. 1 The opportunity exists now to deliver on this long-standing commitment. The Marine Bioregional Planning Process can deliver a world class network of large marine sanctuaries to protect the spectacular north west from oil and gas, fishing and trawling impacts – securing • Kalbarri its future for generations to come. Wild Blue Yonder has been prepared by an alliance of 13 conservation groups to highlight the extraordinary underwater values of this remote and spectacular region, and to encourage their protection.

Nutrients feed continuous coastal current in the world. Currents are microorganisms such as plankton, which in turn are food for larger creatures like fish, sharks, dolphins and whales. The effects of these nutrient booms can hang around for months, creating a tropical feeding frenzy up the food chain. A haven for rare species The north west is home to many nationally protected species in danger of becoming extinct. These include the spectacular whale shark – the world’s largest fish – and 17 species of seahorse and pipefish. Other protected species include 21 species of dolphins and whales, as well as 80 seabird species that visit the area. One third of all types of seasnakes in our oceans, 20% of the world’s sharks, and six of the seven turtle species in the world are found in our north west waters. The north west shelf has one of the largest breeding populations of hawksbill turtles in the world, as well as significant rookeries for green, loggerhead and flatback turtles. The Kimberley coast is the nursery for the largest humpback whale population in the world and Shark Bay is home to the largest remaining population of dugong in the world. Ancient coral reefs Formed 210 million years ago in the late Triassic Period, the reefs of the north west are four times older than the Great Barrier Reef. Unlike the Great Barrier Reef, they include different types of reef – based on coralline algae in the north and hard corals in the survival of coral reefs as ocean warming forces tropical south. species from the coral triangle to move south.

Science supports sanctuaries The evidence tells us marine sanctuaries work Marine sanctuaries (called Marine National Parks by the Federal Government) fully protect both marine life and their homes from extractive industries like mining and fishing. A network of marine sanctuaries around Australia would ensure that our special places and unique marine life are preserved for all Australians to enjoy in the future. Across the world, research provides compelling arguments for the benefits of marine sanctuaries. Marine sanctuaries protect our marine life. The main reason we need marine sanctuaries is to restore and protect biodiversity. There is evidence from all over the world that marine sanctuaries have powerful, positive impacts. For example, a global analysis of coral reefs in sanctuaries showed that reefs in protected areas maintained their coral cover while coral cover declined on unprotected reefs. Marine sanctuaries allow fished populations to recover. In addition to being essential to protect biodiversity, marine sanctuaries can be a very useful juveniles, eggs and larvae from within sanctuaries. complement to fisheries management.
