Great Barrier Reef Marine Park: Established in 1975 for Conservation and Sustainable Use

The Great Barrier Reef Marine Park, established in 1975 under the Great Barrier Reef Marine Park Act, is a pioneering multiple-use marine protected area covering 344,400 km² (133,000 sq mi) off Queensland, Australia. Its creation responded to growing threats: oil drilling proposals, crown-of-thorns starfish outbreaks, and unregulated tourism.

Protection Goals

• Biodiversity Conservation: Safeguard the world's largest coral reef system—2,900+ reefs, 900+ islands, 1,500+ fish species, 400+ coral species, 4,000+ mollusk species, 6 turtle species, dugongs, whales, dolphins.
• Ecological Processes: Protect connectivity between reefs, seagrass meadows, mangroves, and estuaries.
• Cultural Heritage: Recognize Traditional Owners' (70+ Aboriginal and Torres Strait Islander groups) sea country rights and knowledge.
• Sustainable Use: Allow compatible activities (tourism, fishing, research, shipping) under zoning.

Zoning & Management

The park uses a zoning plan (updated 2004):

• Marine National Park (Green) Zones: No-take (33% of area)—highest protection.
• Conservation Park (Yellow): Limited extractive use.
• Habitat Protection (Dark Blue): No trawling.
• General Use (Light Blue): Most activities allowed with permits.

Managed by the Great Barrier Reef Marine Park Authority (GBRMPA) with Australian/Queensland governments and Traditional Owners. UNESCO World Heritage since 1981. Climate change (bleaching), water quality, and coastal development remain existential threats.
