The Great Barrier Reef is a vast area of enormous biological, including human, importance. In recent years the significance of the Great Barrier Reef has been growing because of the increased interest in global climate change and the role of the reef as a potential predictor of the impact of climate change, especially upon the marine environment. The Great Barrier Reef has also legally been important because of its status as a marine park and World Heritage site. To that end, the Great Barrier Reef has specifically been regulated by the Great Barrier Reef Marine Park Authority (‘GBRMPA‘) in accordance with the Great Barrier Reef Marine Park Act 1975 (Cth). Those parts of the reef within the Great Barrier Reef Marine Park (‘Marine Park’) have particular protections under the Act and activities within those parts ordinarily require permission from GBRMPA. Activities authorised by GBRMPA are exempt from the environmental assessment provisions of the Environment Protection and Biodiversity Conservation Act 1999 (Cth) (‘EPBC Act’), the Commonwealth’s principal environmental legislation.
