Marine parks
How each part of a Commonwealth marine park is managed today, in the official Australian Marine Parks zone colours.
Areas the Australian Government has proposed to add to the marine park network.
Managed by state governments, inside 3 nautical miles.
Pressures on dolphins
Where shipping, oil and gas, and coastal pollution overlap with dolphin habitat. Darker red means more pressures stacked in one place.
Places where busy vessel routes cross areas dolphins use. Brighter red means a higher risk of collision.
Individual ship tracks recorded in 2020. Busier corridors show as denser bundles of lines.
Darker areas are where ocean conditions are most degraded, based on water chemistry, oxygen, and food-web productivity.
Factories, refineries, mines and waste facilities that report pollutant releases to the National Pollutant Inventory. Coastal sites can discharge into dolphin habitat.
Lethal shark control equipment that also catches dolphins.
