Nearest land under MARPOL

You must be a specific distance from the nearest land before a discharge at sea can be made.

Some discharge standards under MARPOL require you to be a specified distance from the nearest land before you can make a discharge at sea. For Australia the nearest land boundary runs outside of the Great Barrier Reef (GBR), which means higher discharge standards generally apply within the GBR area.
